    Nanotechnology is enabling the development of a new generation of devices which are able to sense, process and communicate, while being in the scale of tens to hundreds of cubic nanometers. Such small, imperceptible devices enhance not only current applications but enable entirely new paradigms. This paper introduces the concept of nano-cameras, which are built upon nanoscale photodetectors, lenses and electronic circuitry. The state-of-the-art in nanoscale photodetectors and lenses is presented and the expected performance of nano-cameras is numerically evaluated through simulation studies. Finally, the open challenges towards integrating nano-cameras in practical applications and ultimately building the Internet of Multimedia Nano-Things are discussed.

    In-band full duplex power line communications (IBFD-PLC) is an attractive technology that can not only boost the communication throughput, but also help solving networking and security related issues. This paper is focused on the architectural design of IBFD-PLC modems and proposes the adoption of an adaptive analog hybrid to complement the existing technical solutions. Technical details on how to implement such hybrid are presented and its performance in terms of self-interference suppression is assessed. The results show that the proposed hybrid allows to reduce the amount of self-interference around 10 dB more than the solution already presented in the literature.

    With innovation in network design, a strong rise in the specific performance for the end-to-end communication (capacity, latency, connectivity, etc) is expected. This paper tackles the possibility of using an artificial-intelligence-based algorithm to encompass smart routing in a network with a relatively low computation cost. The AI aspect of our method lies in the adaptability of the proposed algorithm: with the need of users and network characteristics changing in time and space, a smart, dynamic approach is required. The application of this AI is done in the specific framework of powerline communication (PLC) used as a front-hauling solution for different communication technologies. Training of the AI processor is done with synthetic data. A huge dataset is generated by using the transmission-line theory based approach to compute the capacity of a powerline link and its behavior with respect to topological information, such as disposition of nodes, their mutual distance and their overall density on the geographical territory. From this bottom-up-generated data, it is eventually possible to infer the capacity of each link in a network from its topological information, which is the only input the AI processor needs.

    In recent times, massive antenna array technologyhas captured significant attention among wirelesscommunication researchers. This is a field with strong potentialto increase rates of data transfer; mitigate interferenceand serve a large number of users simultaneously. Tocontribute further to this emerging technology, this paperpresents an approach for the line-of-sight (LoS) based directionof arrival (DoA) estimation using the electromagnetic(EM) lens-focusing antenna concept. The EM lens focusesthe received signal energy as a function of the angle of arrival(AoA) to a small subset/area of the antenna array. This isadvantageous, as it helps to reduce both hardware implementation(RF chains) and the complexity of signal processingin the large number of antennas system. Furthermore, thisfocusing capability of the EM lens provides additional interferencerejection gain which leads to estimate the DoA ofuser terminals precisely. Hence, in this work, subsets basedantenna selection approach and subspace-based high resolutionDoA estimation algorithms have been considered incombination with the EM lens assisted massive antenna system.In simulations where the DoA is estimated with the EMlens, the results are comparable with conventional methods ofDoA estimation without an EM lens, despite the significantlyreduced overall system complexity.

    Existing Power Line Communications (PLC) channel models consider just the conducted propagation of signals through power lines. However, the natural conformation of power line networks causes a relevant part of the high frequency signals traveling through them to be radiated instead of being conducted. This causes not only deterioration of the signal integrity but also electromagnetic interference (EMI) with devices positioned next to power line cables. This paper describes a bottom-up channel model that includes such radiation effects. With this aim, the physical causes of radiation in power lines are analyzed and their effect on the signal propagation is used to propose a novel power line cable model. Since most of the radiation is caused by common-mode signals, the paper presents a method to describe the propagation of such signals along a power line network and to account for possible mode conversions. Comparisons with lab measurements are finally presented to demonstrate the validity of the model.

    This paper presents an analysis of the noise in multi-conductor power grid networks. This is relevant in multiple-input multiple-output (MIMO) power line communications. In particular, we consider in-building networks and the narrow band spectrum 3–500 kHz. The noise is acquired between the Live and Protective-Earth and between the Neutral and Protective-Earth conductor pairs in a number of outlets. The results show a prominent impulsive time variant behavior. More interestingly, the noise signals in the two conductor pairs are not only correlated, but statistically dependent and in many cases identical. This suggests a form of determinism of the noise signals that can be exploited by spatial noise canceling techniques, one of which is presented in this paper.

    One of the most important tools for the development of the smart grid is simulation. Therefore, analyzing, designing, modeling, and simulating the smart grid will allow to explore future scenarios and support decision making for the grid's development. In this paper, we compare two open source simulation tools for the smart grid, GridLAB-Distribution (GridLAB-D) and Renewable Alternative Power systems Simulation (RAPSim). The comparison is based on the implementation of two case studies related to a power flow problem and the integration of renewable energy resources to the grid. Results show that even for very simple case studies, specific properties such as weather simulation or load modeling are influencing the results in a way that they are not reproducible with a different simulator.

    This article studies how to dimension and control at the system level a fleet of autonomous aerial vehicles delivering goods from depots to customers. Customer requests (jobs) arrive according to a space-time stochastic process.We compute a lower bound for the infrastructure expenditure required to achieve a certain expected delivery time. It is shown that job assignment policies can exhibit a tipping point behavior: One vehicle makes the difference between almost optimal delivery time and instability. This phenomenon calls for careful dimensioning of the system.We thus demonstrate the trade-off between financial costs and service quality. We propose a policy that assigns each incoming job to the vehicle that will do the job faster than other ones, seeking to minimize the overall workload in the system in the long term. This policy is scalable with the number of depots and vehicles, performs optimal in low load, and works well up to high loads. Simulations suggest that it stabilizes the system for any load if the number of vehicles per depot is sufficient.

    This paper presents a novel realistic trajectory generation method for quadrotor helicopters that minimizes the fifth derivative of location with respect to time (crackle) so that smooth trajectories are obtained in typical flight scenarios. The trajectories are implemented with higher order polynomials that grant smoothness in the motor thrust. In order to tune the parameters of the polynomials in the search space, a multi-objective optimization method called particle swarm optimization (PSO) is used. The proposed technique satisfies the constraints imposed by the configuration of the quadrotor helicopter. Other particular constraints can be introduced such as: obstacle avoidance, speed limitation, attitude constraints and actuator torque limitations due to the practical feasibility of the trajectories. Furthermore, a novel adaptive evolutionary feedback controller (EFC) is described and it is used to follow these trajectories. The solution to the control problem is also obtained using PSO. Several numerical results are presented to assess the performance of the proposed trajectory generation and control methods.

    Power distribution grids are exploited by power line communication (PLC) technology to convey high-frequency data signals. The natural conformation of such power line networks causes a relevant part of the high-frequency signals traveling through them to be radiated instead of being conducted. This causes not only electromagnetic interference with devices positioned next to power line cables, but also a consistent deterioration of the signal integrity. Since existing PLC channel models do not take into account losses due to radiation phenomenon, this paper responds to the need of developing accurate network simulators. A thorough analysis is herein presented about the conducted and radiated effects on the signal integrity, digging into differential mode to common mode signal conversion due to network imbalances. The outcome of this work allows each network element to be described by a mixed-mode transmission matrix.

    Our research investigates the concept of interference prediction as an unprecedented approach for interference management and medium access in wireless networks. This paper is a first step in this direction: it proposes and evaluates a simple interference prediction technique that is based on low-complexity learning. Nodes predict the interference situation they expect to experience in the near future and select the most favorable time slot to start the transmission of a multislot message. The performance gain is evaluated in a small-scale fading environment in terms of link outage and delay against random slot selection. Simulation results show that interference prediction is a promising building block for wireless systems. Additional studies are needed to explore advanced techniques and assess their feasibility.

    This paper presents the performance analysis of hybrid rat race coupler, widely used in radio frequency (RF)/wireless communication systems to couple the power in the desired way. The hybrid ring coupler consists of 4 ports, two for the input signals and two for the output signals, where sum and difference patterns of the applied two signals can be obtained at two output ports and usually called sum and difference ports. In this work, the couplers have been designed and simulated at central frequencies (fo) of 2.4 and 10 GHz using different types of substrates such as RT Duroid 5880 and FR4. Furthermore, the coupler has been used for direction finding (angle-of-arrival estimation) application, where we combine the designed hybrid rat race coupler with a simple two antenna elements array (at fo=10GHz and RT Duroid =2.2) and fabricate the circuit in order to validate the performance of the coupler by measuring the direction of arrival (DoA) from and ports. The obtained results show that good performance can be achieved with the designs considered in this paper.

    Nowadays Power Line Communications (PLC) is an established and consolidated technology for communication in smart grids. Although there is always space for enhancements, the power line channel has been widely investigated and a considerable amount of scientific research has led the development of very performing communication solutions. For this reason, in the last years the research efforts about PLC have started moving from pure wired communications to other applications. One of these is using the power line modems (PLM) as network sensors. This means that PLM can not only be used for data transmission, but also to actively monitor the network and provide valuable information about its state and possible anomalies.Some recent papers [1], [2], [3], [4] have shown that continuously monitoring the power line channel response can be used to detect and localize a fault, but also to monitor the cable degradation. In particular, [1] focuses on single-ended measurements, i.e. measuring the echo channel response of a single modem. On the other side, [3], [4] focus on double-ended measurements, i.e. measuring the channel response between two communicating modems. Other techniques based either on single-ended or double-ended measurement have demonstrated that PLM can be used to identify and track the topology of a power line network[5], [6], [7], [8].In this paper, we introduce the possibility of exploiting at the same time both single-ended and double-ended measurements for all the aforementioned diagnostic tasks. This possibility is given by the in-band full duplex (IBFD) technology, which has recently been introduced for PLC. With this technology, PLM modems can at the same time sense the echo response of the transmitted signal and measure the channel response of a signal coming from a far end [9]. The fusion of this double information enhances the diagnostic capability of each communicating node, merging both the advantages of single-ended and double-ended measurements. In fact, single-ended measurements allow good diagnostics of the network part that is close to the transmitting PLM over a radial area, while their efficacy decreases for diagnostic operations in distant network parts.Conversely, double-ended measurements provide the best results for diagnostics in or around the main path connecting the two modems involved, while their performance decreases elsewhere. With IBFD is hence possible not only to sense the electrical properties of a power line network in a radial area around the transmitting PLM, but also to enhance the sensing capability in one direction, based on the position of the second modem. Considering finally many PLM branched to the same network, the sensing capability can be enhanced in different directions at different times, increasing the self diagnostic capabilities of the network.

For this reason, in the last years the research efforts about PLC have started moving from pure wired communications to other applications. One of these is using the power line modems (PLM) as network sensors. This means that PLM can not only be used for data transmission, but also to actively monitor the network and provide valuable information about its state and possible anomalies.Some recent papers [1], [2], [3], [4] have shown that continuously monitoring the power line channel response can be used to detect and localize a fault, but also to monitor the cable degradation. In particular, [1] focuses on single-ended measurements, i.e. measuring the echo channel response of a single modem. On the other side, [3], [4] focus on double-ended measurements, i.e. measuring the channel response between two communicating modems. Other techniques based either on single-ended or double-ended measurement have demonstrated that PLM can be used to identify and track the topology of a power line network[5], [6], [7], [8].In this paper, we introduce the possibility of exploiting at the same time both single-ended and double-ended measurements for all the aforementioned diagnostic tasks. This possibility is given by the in-band full duplex (IBFD) technology, which has recently been introduced for PLC. With this technology, PLM modems can at the same time sense the echo response of the transmitted signal and measure the channel response of a signal coming from a far end [9]. The fusion of this double information enhances the diagnostic capability of each communicating node, merging both the advantages of single-ended and double-ended measurements. In fact, single-ended measurements allow good diagnostics of the network part that is close to the transmitting PLM over a radial area, while their efficacy decreases for diagnostic operations in distant network parts.Conversely, double-ended measurements provide the best results for diagnostics in or around the main path connecting the two modems involved, while their performance decreases elsewhere. With IBFD is hence possible not only to sense the electrical properties of a power line network in a radial area around the transmitting PLM, but also to enhance the sensing capability in one direction, based on the position of the second modem. Considering finally many PLM branched to the same network, the sensing capability can be enhanced in different directions at different times, increasing the self diagnostic capabilities of the network.},

    Power distribution grids are exploited by Power Line Communication (PLC) technology to convey information in the context of Smart Grids and In-Home environments [1]. Their feature of using the existing cable infrastructure has the advantage for utilities of being proprietary and for residential users of granting wider range and possibly higher coverage compared to wireless technologies. On the other hand, the structure of such power line networks causes a relevant part of the high frequency signals traveling through them to be radiated instead of being conducted. This induce not only electromagnetic interference (EMI) with devices located next to power line cables, but also a consistent deterioration of the signal integrity.Although this phenomenon is known by the PLC community since its foundation, only few research papers deal with it [2], [3]. Since existing PLC channel models do not take into account losses due to radiation phenomena, this paper responds to the need of developing accurate network simulators.

    Smart microgrids are a possibility to reduce complexity by performing local optimization of power production, consumption and storage. We do not envision smart microgrids to be island solutions but rather to be integrated into a larger network of microgrids that form the future energy grid. Operating and controlling a smart microgrid involves optimization for using locally generated energy and to provide feedback to the user when and how to use devices. This chapter shows how these issues can be addressed starting with measuring and modeling energy consumption patterns by collecting an energy consumption dataset at device level. The open dataset allows to extract typical usage patterns and subsequently to model test scenarios for energy management algorithms. Section 3 discusses means for analyzing measured data and for providing detailed feedback about energy consumption to increase customers’ energy awareness. Section 4 shows how renewable energy sources can be integrated in a smart microgrid and how energy production can be accurately predicted. Section 5 introduces a self-organizing local energy system that autonomously coordinates production and consumption via an agent-based energy auction system. The final section discusses how the proposed methods contribute to sustainable growth and gives an outlook to future research.

    In this paper, we propose a low complexity based direction finding approach in an electromagnetic (EM) lens assisted massive antenna system. The EM lens provide the advantage of focusing the received signal energy on a small area/subset of the antennas array at the base station (BS). Thus,by taking the advantage of this focusing ability, we propose a complexity reduced sum and difference pattern technique to find the direction of arrival (DoA) of the received radio frequency (RF) signals. The proposed technique is simple and implemented in RF.

    Nowadays, the population of connected cellular devices around the world is growing exponentially. In order to provide high-quality and seamless coverage, small-cell networks are being employed by telecommunication operators to increase spatial fragmentation and the reuse of cellular frequencies [1]. The downside of this practice lies in the necessity for an additional step in the network's hierarchy, namely the back-haul section needed between the small cells and the Radio Access Network's (RAN) hub, located in the macro-cell's antenna.Supporting the customers traffic requirements, reliability, easy deployment and maintenance and not exploiting end-user spectrum to avoid interference are basic ground rules to keep in mind when designing this back-haul section. Naturally, specific needs pertain to different application scenarios, which is the reason why there is no unique method to design an infrastructure apt to transfer data from small-cells to the RAN's hub. Both wired and wireless solutions are currently employed for this application, although neither of them offer the universally optimal solution, as there is a trade of between installation/maintenance costs, data rate capabilities and environmental factors to consider. The power-line infrastructure offers an interesting asset for this application because of its wide-spread reach of devices.

    LTE is the most recent standard for the mobile cellular communication. To achieve high speed communications, multi-carrier modulations have been adopted both for the downlink and the uplink. In the LTE downlink, OFDMA (the multi-user version of OFDM) has been chosen. The LTE uplink uses instead SC-FDMA modulation, an OFDM alternative. In this work, the use of CB-FMT, jointly with SC-FDMA, is analyzed in the high mobility scenario. Numerical results show that CB-FMT outperforms SC-FDMA in several cases. Thus, an adaptive implementation architecture that allows to flexibly choose the modulation scheme is proposed to maximize the achievable rate. Furthermore, for compliance with existing LTE parameters, frequency domain zero padded CB-FMT is proposed, and the problem of designing optimal capacity wise waveforms is considered.

    In this work, we propose a distributed cubatureinformation filter based multi-object tracking method with aninformation weighted selection for unmanned aerial vehicle (UAV)networks. In an UAV network, multiple UAVs can observemultiple objects in the region of interest. Further, the UAVs canexchange the objects local information among themselves andfuse them together to obtain the global state of the objects. Asthe number of UAVs in the network increases, the informationexchange among the UAVs suffers from scalability, bandwidthand energy limitations. Thus, it is usually desirable to allow onlya desired number of UAVs with highly relevant information toparticipate in the information exchange. In our approach, theinnovation vector within the information filtering framework isused to calculate the amount of information associated witheach UAV. Further, a threshold based selection mechanism isproposed to facilitate the UAVs to take independent decisions onwhether to participate in the information exchange or not. In theproposed method, the UAVs take the decision to participate in theinformation exchange based on the information associated with adynamic subset of objects known as priory objects while keepingthe total number of information exchanges in the network to adesired number (on average).

    The reliability and quality of electrical power networks are affected by the occurrence of electrical faults. In this paper, we propose a novel method to identify the occurrence of faults in distribution networks, based on impedance measurements performed at the central distribution office. The measurements can be performed using PLC modems that belong to the energy metering infrastructure. The fault is detected by means of continuous impedance monitoring and afterwards its distance from the central office is estimated using the same measurement traces, without requiring additional information. Different type of faults are tested, and the effect of the measurement bandwidth and the electrical noise on the measurement is also assessed.

    The theory of pulse-coupled oscillators provides a framework to formulate and develop self-organizing synchronization strategies for wireless communications and mobile computing. These strategies show low complexity and are adaptive to changes in the network. Even though several protocols have been proposed and theoretical insight was gained there is no proof that guarantees synchronization of the oscillator phases in general dynamic coupling topologies under technological constraints. Here, we introduce a family of coupling strategies for pulse-coupled oscillators and prove that synchronization emerges for systems with arbitrary connected and dynamic topologies, individually changing signal propagation and processing delays, and stochastic pulse emission. It is shown by simulations how unreliable links or intentionally incomplete communication between oscillators can improve synchronization performance.

    In this paper, the effects of impedance matching in the PLC systems in terms of capacity are investigated. Two different matching methods at the transmitter port are introduced. Since the punctual impedance matching is a difficult task for the electronics, firstly we illustrate an algorithm useful to measure the input PLC channel impedance at both the transmitter and the receiver sides. This is of fundamental importance for the matching operations. Once the input impedances are retrieved, we compare the achievable system capacity obtainable with the transmitter impedance optimized applying the considered matching criteria. Furthermore, the channel capacity loss with simplified and more implementable transmitter impedance profiles are investigated.

    This paper discusses the issue of energy-efficiency in power line communication (PLC) systems and introduces decode-and-forward (DF) energy-harvesting based relaying. The performance of the proposed system is analyzed in terms of the energy efficiency for which accurate analytical expressions are derived. To highlight the achievable gains, we also evaluate the performance of both the conventional DF relaying and the direct-link systems. The presented simulated results clearly demonstrate the correctness of our analysis as well as the advantage of the proposed system over the conventional relaying and direct-link approaches. Additionally, it is shown that the proposed scheme will become more energy efficient as the harvested noise energy becomes larger.

    This paper considers Electromagnetic Compatibility (EMC) aspects in the context of Power Line Communication (PLC) systems. It offers a complete overview of both narrow band PLC and broad band PLC EMC norms. How to interpret and translate such norms and measurement procedures into typical constraints used by designers of communication systems,is discussed. In particular, the constraints to the modulated signal spectrum are considered and the ability of pulse shaped OFDM (PS-OFDM), used in most of the PLC standards as IEEE P1901 and P1901.2, to fulfill them is analyzed. In addition, aiming to improve the spectrum management ability, a novel scheme named Pulse Shaped Cyclic Block Filtered Multitone modulation (PSCB-FMT)is introduced and compared to PS-OFDM. It is shown that, PS-CB-FMT offers better ability to fulfill the norms which translates in higher system capacity.

    This article compares measures for quantifying the level of inhomogeneity of a given spatial point pattern. Comparisons are based on two main metrics: first, we evaluate the performance of the measures on both certain stochastic point processes and on very specific point patterns designed to expose potential weaknesses of the inhomogeneity measures. Second, we evaluate the computational complexity of the measures. Results show that choosing a measure is a tradeoff between accurate assessment of inhomogeneity and computational complexity. The only exception is the proposed extended wrap-around measure, which is performing well in terms of both metrics.

    The knowledge of the topology of a wired network is often of fundamental importance. For instance, in the context of power line communications networks it is helpful to implement data routing strategies, while in power distribution networks and smart microgrids it is required for grid monitoring and for power flow management. In this paper, we use the transmission line theory to shed new light and to show how the topological properties of a wired network can be found exploiting admittance measurements at the nodes. An analytic proof is reported to show that the derivation of the topology can be done in complex networks under certain assumptions. We also analyze the effect of the network background noise on admittance measurements. In this respect, we propose a topology derivation algorithm that works in the presence of noise. We finally analyze the performance of the algorithm in a setup that is typical of power line distribution networks.

    Out-of-Band (OOB) emissions are a drawback that affect the OFDM scheme. To mitigate the issue, time domain pulse shaping (PS) has been introduced in the known Pulse Shaped OFDM (PS-OFDM) scheme. This paper extends the PS idea to the Cyclic Block Filtered Multitone (CB-FMT) modulation scheme. CB-FMT represents a filtered multitone modulation scheme where, however, the filter bank uses cyclic convolutions instead of linear convolutions. However, while PS-OFDM starts from OFDM that has sinc-like sub-channel frequency responses, Pulse Shaped CB-FMT (PS-CB-FMT) deploys well frequency localized sub-channel pulses. Therefore, PS-CB-FMT has a more confined spectrum which is of particular importance in applications that have to offer agile spectrum usage to fulfill norms and coexistence with other systems. One of these applications is Power Line Communication (PLC) which is subject to strict EMC regulations. In this context, we show that PS-CB-FMT is capable to fulfill the spectral masks much more efficiently than PS-OFDM adopted in all relevant PLC standards. In turn, this provides improved capacity performance.

    In this paper, a novel switched hardware approach to angle of arrival (AoA) estimation in radio systems that signal using quadrature amplitude modulations (QAM) is presented. The proposed algorithm, namely constellation statistical pattern identification and overlap (CSP-IDO), is based on the comparison of the probability density functions of successive signal snapshots from antennas (asynchronous approach). Contrariwise, other AoA techniques such as differential methods, beamforming and root-MUSIC are designed to acquire in parallel signals from the antennas (synchronous approach). CSP-IDO allows a significantly reduced hardware usage with respect to synchronous methods, without deteriorating precision. The proposed algorithm used with a time switched antenna approach leads to better performance in terms of overall hardware complexity, power consumption and possibly costs. Furthermore, CSP-IDO is robust to transmitter hardware impairments with respect to synchronous methods.

    The aim of this paper is to provide a realistic stochastic trajectory generation method for unmanned aerial vehicles that offers a tool for the emulation of trajectories in typical flight scenarios. Three scenarios are defined in this paper. The trajectories for these scenarios are implemented with quintic B-splines that grant smoothness in the second-order derivatives of Euler angles and accelerations. In order to tune the parameters of the quintic B-spline in the search space, a multi-objective optimization method called particle swarm optimization (PSO) is used. The proposed technique satisfies the constraints imposed by the configuration of the unmanned aerial vehicle (UAV). Further particular constraints can be introduced such as: obstacle avoidance, speed limitation, and actuator torque limitations due to the practical feasibility of the trajectories. Finally, the standard rapidly-exploring random tree (RRT*) algorithm, the standard (A*) algorithm and the genetic algorithm (GA) are simulated to make a comparison with the proposed algorithm in terms of execution time and effectiveness in finding the minimum length trajectory.

    Although powerlines have not been designed for data transmission, recent technical developments in Power Line Communication (PLC) have pushed the offered capacity much higher than expected, making PLC an interesting technology for last mile connections like the back-hauling considered in this work. On the other hand, cellular traffic is doubling every year, and this growth trend is not expected to end soon. Small cells have been advocated as a solution to fragment the network and increase the local capacity; in addition, new generation of mobile communication is likely to employ high frequency bands that will cover smaller areas, hence, an increase in cell density is expected. This will increase the challenge for the realization of a cost effective high performance back-haul to bridge the small cell network with the core network. Nowadays, the back-haul portion of the network is either wireless or high speed wireline (ADSL, optical fiber). This paper introduces the idea of employing PLC to support back-hauling for small radio cells. To assess the backhaul requirements and the performance of the integrated radio-PLC network, a topology model is proposed to describe both the small radio cell network layout and the power delivery grid used to both power and “data” connect the base stations. Then, a parametric cell traffic model is considered to measure the overall traffic to be transported through the PLC network and determine whether (under the power grid topology constraints) the PLC back-haul can meet the traffic demands.

    The integration of renewable energy sources increases the complexity in maintaining the power grid. In particular, the highly dynamic nature of generation and consumption demands for a better utilization of energy resources, which seen the cost of storage infrastructure, can only be achieved through demand-response. Accordingly, the availability of energy and potential overload situations can be reflected using a price signal. The effectiveness of this mechanism arises from the flexibility of device operation, which is nevertheless heavily reliant on the exchange of information between the grid and its consumers. In this paper, we investigate the capability of an interactive energy management system to timely inform users on energy usage, in order to promote an optimal use of local resources. In particular, we analyze data being collected in several households in Italy and Austria to gain insights into usage behavior and drive the design of more effective systems. The outcome is the formulation of energy efficiency policies for residential buildings, as well as the design of an energy management system, consisting of hardware measurement units and a management software. The Mjölnir framework, which we release for open use, provides a platform where various feedback concepts can be implemented and assessed. This includes widgets displaying disaggregated and aggregated consumption information, as well as daily production and tailored advices. The formulated policies were implemented as an advisor widget able to autonomously analyze usage and provide tailored energy feedback. The advisor is estimated leading to a potential of 34% of savings using measurement data from the GREEND dataset.

    This paper proposes a synthetic statistical top-down MIMO power line communications channel model based on a pure phenomenological approach. The basic idea consists of directly synthesizing the experimental channel statistical properties to obtain an extremely compact model that requires a small set of parameters. The model is derived from the analysis of the in-home 2 × 3 MIMO PLC channel data set obtained by the ETSI Specialist Task Force 410 measurement campaign in the band 1.8–100 MHz. The challenge of modeling the channel statistical correlation, exhibited among the frequencies and between the MIMO modes, in compact form is tackled and it is shown that a small set of parameters can be used to reconstruct such a correlation behavior. The model is validated and compared to the measured channels, showing a good agreement in terms of average channel gain, root-mean-square delay spread, coherence bandwidth, and channel capacity distribution.

    Direction of arrival (DoA) estimation in the massive antenna systems with reduced hardware and signal processing complexity is a challenging task. To address the issue, this paper presents an approach to estimate the DoA in a large number of antennas system combined with an electromagnetic (EM) lens. An EM lens has the ability to focus the received signal energy as a function of the angle of arrival (AoA) to a small subset/area of the antenna array at the base station (BS). Thus, it helps to estimate the DoA efficiently while minimizing the number of radio frequency (RF) chains and the associated signal processing costs. Moreover, by defining a cluster over a group of closely spaced subsets, the computational efforts of the DoA estimation algorithm can be further reduced.

    To analyse user behaviour and energy consumption data in contemporary and future households, we need to monitor electrical appliance features as well as ambient appliance features.For this purpose, a distributed measurement system is required, which measures the entire power consumption of the household, the power consumption of selected household appliances, and the effect of these appliances on their environment.In this paper we present a distributed measurement system that records and monitors electrical household appliances. Our low-cost measurement system integrates the YaY smart meter, a set of smart plugs, and several networked ambient sensors.In conjunction with energy advisor tools the presented measurement system provides an efficient low-cost alternative to commercial energy monitoring systems by surpassing them with machine learning techniques, appliance identification methods, and applications based on load disaggregation.

    Power distribution networks have peculiar characteristics that make sensing and control challenging. The topological structure is complex and often variable; different type of faults are common and often cause undetectable damage to the network; the power cables of aerial and especially those of buried lines are subject to aging that eventually causes degradation in power and signal distribution. In this paper, we show different techniques to monitor all these characteristics by leveraging the recently investigated in-band full duplex power line technology.As an explanatory example, we show simulation results about monitoring of the cable aging phenomenon. We also present a technique that can be used to precisely localize the detected faults or cable imperfections.

    A major aspect in power line distribution networks is the constant monitoring of the network properties. With the advent of the smart grid concept, distributed monitoring has started complementing the information of the central stations. In this paper, power line communications modems deployed throughout the network provide a tool to monitor high-frequency components of the signals traveling through a power line network. We propose, therefore, to use them not only as communication devices but also as network sensors. Besides classical voltage measurements, these sensors can be designed to monitor high-frequency impedances, which provide useful information about the power line network, as for instance status of the topology, cable degradation, and occurrence of faults. In this paper, we provide a technical analysis of different voltage and impedance measurement techniques that can be integrated into power line modems. We assess the accuracy of the techniques under analysis in the presence of network noise, and we discuss the statistical characteristics of the measurement noise. We finally compare the performances of the examined techniques when applied to the fault detection problem in distribution networks, in order to establish which technique gives more accurate results

    Communication systems utilise correlation filters to detect waveforms. In a broader sense, these filters examine the amount of resemblance between a template pattern and the input pattern. In the domain of smart grids, many applications require the detection of active electrical appliances, their condition as well as their current state of operation.Furthermore, the identification of power eaters, the recognition of ageing effects, and the forecast of required maintenance represent important challenges in (home) energy management systems.In this paper, we examine the applicability of correlation filters as a possible solution to meet such challenges. First, we introduce the concept of predictability to power consumption patterns of electrical appliances.Second, we present our concept and the implementation of correlation filters for this kind of application. The correlation filters utilise a particular consumption pattern of an electrical appliance to detect the respective appliance in energy readings from smart meters and smart plugs.Lastly, we assess the performance of the correlation filters on the real-world energy consumption dataset GREEND, which provides readings from smart meter data as well as appliance-level measurement equipment. As the results approve, the correlation filters show a good performance for appliances with predictable consumption patterns such as refrigerators, dishwashers, or washing machines. Thus, we propose that future work should evaluate the applicability of correlation filters in appliance diagnosis systems.

    A fine-grained and real-time energy data provided by the smart meters is one of the main facilitators for achieving improved energy efficiency in future smart grids. Further disaggregating the information provided by smart meters into energy consumption of individual appliances, often referred as appliance load disaggregation (ALD), can provide valuable information.In this paper, we propose a non-intrusive ALD based on the maximum a-posterior particle filter (MAP-PF). The proposed non-intrusive ALD allows to identify state of an appliance by utilizing the probabilistic appliance models and the aggregatedpower of the household, measured by a single smart meter. A combination of multi-state appliances modeled by hidden Markov models and the corresponding aggregated power is modeled by a factorial hidden Markov model (FHMM). The FHMM models the household as a finite state machine with discrete states. Theproposed MAP-PF based ALD uses the principles of particle filter to infer the maximum probable state of the household and subsequently, the state of each appliance at a given time under the Viterbi framework. Furthermore, we evaluated the proposed method using a simulated and well known real-world data sets incomparison with the PF based ALD. In our simulation results, the proposed method achieves similar or higher estimation accuracy with significantly less computational complexity compared to the PF based ALD method

    This article analyzes two classes of job selection policies that control how a network of autonomous aerial vehicles delivers goods from depots to customers. Customer requests(jobs) occur according to a spatio-temporal stochastic process not known by the system. If job selection uses a policy in which the first job (FJ) is served first, the system may collapse to instability by removing just one vehicle. Policies that serve the nearest job (NJ) first show such threshold behavior only in some settings and can be implemented in a distributed manner. The timing of job selection has significant impact on delivery time and stability for NJ while it has no impact for FJ. Based on these findings we introduce a methodological approach for decision making support to set up and operate such a system, taking into account the trade-off between monetary cost and service quality.In particular, we compute a lower bound for the infrastructure expenditure required to achieve a certain expected delivery time.The approach includes three time horizons: long-term decisions on the number of depots to deploy in the service area, midterm decisions on the number of vehicles to use, and short-term decisions on the policy to operate the vehicles.

    This paper presents a design for a low-cost research robot based on the small size of the Hexbug Spider toy. Our basic modification replaces the robot head with a 3D-printed adapter, consisting of two parts to provide space for sensors, a larger battery, and a printed circuit board (PCB) with Arduino microcontroller, Wi-Fi module, and motor controller. We address the assembling process of such a robot and the programming using Arduino studio. The presented prototype costs less than 70 Euro, and is suitable for swarm robotic experiments and educational purposes.

    The structured compressed sensing based framework for the estimation of NarrowBand Interference (NBI) in power line communication is proposed, which facilitates in-home interconnection and prevents the wired consumer electronics devices from contamination of NBI. To recover the NBI accurately, the Structured Compressed Sensing (SCS) theory is introduced, and the method of SCS based Temporal Differential Measuring (SCS-TDM) is proposed, which fully exploits the temporal correlation of NBI. By exploiting the repeated training sequences, the NBI measurements matrix is acquired. With the exploitation of the prior partial support information, a more effective greedy algorithm, structured prior aided sparsity adaptive matching pursuit, is proposed. The performance of the proposed algorithm is theoretically guaranteed, and simulation results validate that the proposed method significantly outperforms existing counterparts.

    In this paper, we consider the identification of a smart grid network topology by means of admittance measurements performed at the network nodes. We show how the application of the transmission line theory allows the identification of the node-to-node connections. Thereby, a topology identification algorithm is presented. The identification error due to the network noise is reduced by performing repeated measurements, either at different time instants or over a set of frequencies, at each network node. The information is then fused by means of the total least square regression technique, which is also compared to a simpler estimator. A thorough analysis of the results is then presented, which shows good reliability of the proposed algorithm.

    Most, if not all, existing studies on power line communication (PLC) systems as well as industrial PLC standards are based on orthogonal multiple access schemes, such as orthogonal frequency-division multiplexing and code-division multiple access. In this paper, we propose non-orthogonal multiple access (NOMA) for decode-and-forward cooperative relaying PLC systems to achieve higher throughput and improve user fairness. To quantitatively characterize the proposed system performance, we also study conventional cooperative relaying (CCR) PLC systems. We evaluate the performance of the two systems in terms of the average capacity. In this respect, accurate analytical expressions for the average capacity are derived and validated with Monte Carlo simulations. The impact of several system parameters, such as the branching, impulsive noise probability, cable lengths, the power allocation coefficients, and input signal-to-noise ratio, is investigated. The results reveal that the performance of the proposed NOMA-PLC scheme is superior compared with that of the CCR-PLC system. It is also shown that the NOMA-PLC system can be more effective in reducing electromagnetic compatibility associated with PLC and that increasing the network branches can considerably degrade the performance. Moreover, optimizing the power allocation coefficients is found to be of utmost importance to maximize the performance of the proposed system.

We apply a dynamic stochastic model inserted into a Kalman filter formulation to track the clock evolution of oscillators and achieve synchrony to a central time reference. Indoor and outdoor experiments performed with commercially available wireless sensor platforms over several days serve as a proof of concept and show the synchronization accuracy under stable and varying temperature conditions.

    Cyber-Physical Systems (CPS) find applications in a number of large-scale, safety-critical domains e.g. transportation, smart cities, etc. As a matter of fact, the increasing interactions amongst different CPS are starting to generate unpredictable behaviors and emerging properties, often leading to unforeseen and/or undesired results. Rather than being an unwanted byproduct, these interactions could, however, become an advantage if they were explicitly managed, and accounted, since the early design stages. The CPSwarm project, presented in this paper, aims at tackling these kinds of challenges by easing development and integration of complex herds of heterogeneous CPS. Thanks to CPSwarm, systems designed through a combination of existing and emerging tools, will collaborate on the basis of local policies and exhibit a collective behavior capable of solving complex, real-world, problems. Three real-world use cases will demonstrate the validity of foundational assumptions of the presented approach as well as the viability of the developed tools and methodologies.

    The orthogonal design of a cyclic block filtered multititone modulation (CB-FMT) system is addressed. CB-FMT is a filter bank modulation scheme that uses frequency confined prototype pulses, similarly to FMT. Differently from FMT, where the linear convolution is used, the cyclic convolution is exploited in CB-FMT. This allows to efficiently implement the system via a concatenation of discrete Fourier transforms. The necessary and sufficient orthogonality conditions are derived in time domain and frequency domain. Then, these conditions are expressed in matrix form, and the prototype pulse coefficients are parameterized with hyper-spherical coordinates. The effect of a linear time-variant transmission medium is discussed.In such a scenario, the optimal filter bank orthogonal design is considered with the objective of maximizing either the in-band-to-out-band sub-channel energy ratio or the achievable rate. Numerical results and comparisons show the performance improvements attainable with several designed optimal pulses also with respect to the use of the baseline root-raised-cosine pulse.

    The two major sources of disturbances for an efficient and reliable data transmission through power lines, known as power line communication (PLC), are impulsive noise (IN) and narrow band interference (NBI). In this paper, we propose an algorithm to cancel the IN and NBI simultaneously for an OFDM based PLC system. The proposed method exploits the duality of the problem, where the IN is sparse in the time domain and the NBI is sparse in the frequency domain. By virtue of this duality, we use multiple signal characterization (MUSIC) algorithm to estimate both the IN support (in time domain) and the frequency of NBI (in frequency domain). Furthermore, the minimum mean square error (MMSE) estimator is used to estimate the amplitude and phase of IN samples at the determined locations and the least square (LS) estimator is used to estimate the amplitude and phase of the NBI. Finally, the estimated IN and NBI are canceled out from the received signal, providing noise mitigated samples for demodulation. The performance of the proposed scheme is verified via numerical simulations.

    This paper proposes a novel algorithm for user localization using the angle of arrival (AoA) concept. We propose to combine the electromagnetic (EM) lens with the massive multiple-input multiple-output (MIMO) antenna array at the base station (BS). EM lens have the advantage of focusing the signal power on a subset of antennas as a function of the AoA. Thus, the provide an opportunity to estimate the location of user more efficiently with reduced number of radio frequency (RF) chains and computational costs. The obtained numerical results have shown that the EM lens based massive MIMO is capable of providing better AoA estimation.

    Unmanned Aerial Vehicles (UAVs) localization has become crucial in recent years, mainly for navigation or self-positioning and for UAV based security monitoring and surveillance. In this paper, azimuth and elevation radio positioning of UAVs are considered. The localization is based on multiple differential phase-of-arrival measures exploiting a 3-Axial Uniform Linear Array of antennas. An ad hoc particle filtering algorithm is applied to improve the positioning performance using a dynamic motion model. A novel adaptive algorithm, namely, Particles Swarm Adaptive Scattering (PSAS), is proposed to increment the algorithm stability and precision. To assess performance a Confined Area Random Aerial Trajectory Emulator (CARATE) algorithm has been developed to generate actual paths of flying UAVs. The algorithm performance is compared with the baseline method and with the average trajectory Cramér Rao lower bound to show the effectiveness of the proposed algorithm.

    Designing distributed protocols with limited requirements for exchange of feedback information between the nodes is a key element in the development of cognitive and self-organizing ad hoc networks. We argue that the Minority Game (MG) and its variations can constitute useful tools towards this direction. In particular, the MG formulation is well suited for addressing a variety of resource allocation problems in self-organizing wireless networks. In this paper we illustrate the employment of MGs by presenting a paradigm of an MG-based model for dynamic channel allocation.

    The days where swarms of Unmanned Aerial Vehicles (UAVs) will occupy our skies are fast approaching due to the introduction of cost-efficient and reliable small aerial vehicles and the increasing demand for use of such vehicles in a plethora of civil applications. Governments and industry alike have been heavily investing in the development of UAVs. As such it is important to understand the characteristics of networks with UAVs to enable the incorporation of multiple, coordinated aerial vehicles into the air traffic in a reliable and safe manner. To this end, this survey reports the characteristics and requirements of UAV networks for envisioned civil applications over the period 2000-2015 from a communications and networking viewpoint. We survey and quantify quality-of-service (QoS) requirements, network-relevant mission parameters, data requirements and the minimum data to be transmitted over the network. Furthermore, we elaborate on general networking related requirements such as connectivity, adaptability, safety, privacy, security, and scalability. We also report experimental results from many projects and investigate the suitability of existing communication technologies for supporting reliable aerial networking.

    In this work, we propose a multi-camera object tracking method with surprisal observations based on the cubature information filter in visual sensor networks. In multi-camera object tracking approaches, multiple cameras observe an object and exchange the object’s local information with each other to compute the global state of the object. The information exchange among the cameras suffers from certain bandwidth and energy constraints. Thus, allowing only a desired number of cameras with most informative observations to participate in the information exchange is an efficient way to meet the stringent requirements of bandwidth and energy. In this paper, the concept of surprisal is used to calculate the amount of information associated with the observations of each camera. Furthermore, a surprisal selection mechanism is proposed to facilitate the cameras to take independent decision on whether their observations are informative or not. If the observations are informative, the cameras calculate the local information vector and matrix based on the cubature information filter and transmit them to the fusion center. These cameras are called as surprisal cameras. The fusion center computes the global state of the object by fusing the local information from the surprisal cameras. Moreover, the proposed scheme also ensures that on average only a desired number of cameras participate in the information exchange. The proposed method shows a significant improvement in tracking accuracy over the multi-camera object tracking with randomly selected or fixed cameras for the same number of average transmissions to the fusion center.

    We present an algorithm for autonomous network calibration of visual sensor networks, which become more and more pervasive since they can be found in various everyday life environments. The proposed algorithm works in a fully decentralized way and minimizes usage of cost-intensive vision algorithms. To achieve network calibration, our approach relies on jointly detected objects and geometric relations between camera nodes. Distances and angles are the only information required to be exchanged between nodes. The process works iteratively until cameras have determined the relative position and orientation of their neighbors. Preliminary results are demonstrated using our visual sensor network simulator.

The proposed algorithm works in a fully decentralized way and minimizes usage of cost-intensive vision algorithms. To achieve network calibration, our approach relies on jointly detected objects and geometric relations between camera nodes. Distances and angles are the only information required to be exchanged between nodes. The process works iteratively until cameras have determined the relative position and orientation of their neighbors. Preliminary results are demonstrated using our visual sensor network simulator.},

    Power-line communications (PLC) have enabled many smart grid applications over the past years. Secure communications over such channels, however, remains a crucial aspect for the successful realization of smart grids. Many techniques have been proposed in the literature to achieve this and the most recent of which is the adoption of physical layer security for PLC systems. Unlike the existing work, in this paper, we investigate physical layer security of cooperative relaying PLC systems with artificial noise in the presence of an eavesdropper. The system performance is evaluated in terms of the ergodic secrecy capacity. In light of this, we derive a mathematical expression for the ergodic secrecy capacity and validate it with Monte Carlo simulations. Results reveal that the proposed system can significantly enhance the security of PLC systems.

    We present a wireless sensor network, deployed andtested for real aircraft applications. By employing IEEE802.15.4-2011 UWB compliant transceivers, with a timeslotted channel access protocol, characteristics of indoorpropagation are studied. A test setup in an aircraft’s emptypassenger cabin is presented and wireless channel featuresare analysed. Specifically, coherence time and shadowingare determined, which constitute the fundamental step forretrieving a generalized channel model.

    In this paper, we investigate the energy efficiency performance of Multiple-Input-Multiple-Output (MIMO) relay-assisted Power Line Communication (PLC) networks. We consider a half-duplex Decode and Forward (DF) relay system and compare its performance for both uniform time allocation and optimized time allocation strategies. Based on realistic MIMO PLC channels, obtained from the European Telecommunications Standards Institute (ETSI) Specialist Task Force (STF) 410 field measurement campaign that was performed in six European countries, we show that depending on the idle power consumption of MIMO PLC modems in the relay network, possible energy saving gain can be obtained by using DF MIMO PLC relays.

This is of fundamental importance since a good model represents a quick evaluation tool for new standards or devices, allowing a considerable saving in time and costs. The aim of this paper is to discuss a novel top-down MIMO PLC synthetic channel model, able to numerically emulate a real PLC environment. First, the most common channel modeling strategies are briefly described, highlighting strengths and weaknesses. Afterwards, the basic model approach is described considering the SISO scenario. The implementation strategy is then extended to the MIMO case. The validity of the proposed model is proved making a comparison between the simulated channels and channels obtained with measurements in terms of both performance and statistical metrics. The focus is on the broadband frequency spectrum.

    This paper analyzes the reciprocity, symmetry and port decoupling effect in real home PLC networks. The reciprocity has an impact on the fact that the input and output ports of a PLC link are decoupled, and the study on the symmetry can explain the reason for the decoupling effect. The analysis of experimental data in the band 2-100 MHz shows that the PLC channel is reciprocal and that the input-output ports are largely decoupled. In turn, the port decoupling property implies that impedance matching at the transmitter and receiver ports can be implemented independently one from the other. That is, the choice of the receiver impedance does not have effect on the choice of the transmitter impedance and vice versa, in home broad band PLC systems.

    Sensors have an essential role in the currently emerging Internet of Things (IoT) whereby these resource constrained nodes sense the environment, process the sensed data and forward it to a central entity. As some of this data might be sensitive in nature, it is crucial to ensure certain security guarantees on the sensed data such as integrity, confidentiality, and authenticity. Certain cryptographic primitives offer these security properties based on the assumption that each node is capable of generating and storing its secret key securely. Existing solutions for secure key storage are based on secure non-volatile memory. Physically Unclonable Functions (PUFs) are lightweight hardware security primitives that bind a unique key to each device and provide resistance against key compromise attacks as the key exists in form of hardware manufacturing variations, which are difficult to read as compared to memory based alternative solutions. Therefore, in this work we present a PUF-based lightweight, secure key generation and storage framework for resource constrained sensor nodes. Our implementation of a ring oscillator (RO) PUF based key generation scheme shows that the PUF based key generation consumes only a small part of a typical visual sensor node’s resources.

    We propose and prove a theorem that allows the calculation of a class of functionals on Poisson point processes that have the form of expected values of sum–products of functions. In proving the theorem, we present a variant of the Campbell–Mecke theorem from stochastic geometry. We proceed to apply our result in the calculation of expected values involving interference in wireless Poisson networks. Based on this, we derive outage probabilities for transmissions in a Poisson network with Nakagami fading. Our results extend the stochastic geometry toolbox used for the mathematical analysis of interference-limited wireless networks.

    The convergence and precision of synchronization algorithms based on the theory of pulse-coupled oscillators is evaluated on programmable radios. Measurements in different wireless topologies show that such algorithms reach precisions in the low microsecond range. Based on the observation that phase rate deviation among radios is a limiting factor for the achievable precision, we propose a distributed algorithm for automatic phase rate equalization and show by experiments that an improved precision below one microsecond is possible in the given setups. It is also experimentally demonstrated that the stochastic nature of coupling is a key ingredient for convergence to synchrony. The proposed scheme can be applied in wireless systems for distributed synchronization of transmission slots, or sleep cycles.

    Multicast video streaming over IEEE 802.11 is unreliable due to the lack of feedback from receivers. High data rates and variable link conditions require feedback from the receivers for link estimation to improve reliability and rate adaptation accordingly. In this paper, we validate on a test platform an application-layer rate-adaptive video multicast streaming framework using an 802.11 ad-hoc network applicable for mobile senders and receivers. Experimental results serve as a proof of concept and show the performance in terms of goodput, delay, packet loss, and received video quality.

    This article introduces a framework to computedecision making policies (mission planning) for a UAV-baseddelivery system serving impatient customers. Customers arriveon a finite number of locations L separated by arbitrary butfixed distances and eventually leave if not served. Policies seekto minimize the average net cost (maximize the average netrevenue), i.e. loss from customers’ abandonment deprived ofthe revenue from successful services. We introduce a novelmodel for the stochastic and dynamic pickup and deliveryproblem based on semi-Markov decision processes, and showthe dependence of the optimal average net cost on the minimumdistance between locations δ. Furthermore, we propose afeature-based state aggregation method to overcome the curseof dimensionality due to the exact modeling. The selection ofrelevant features is based on their correlation with the optimalperformance. We show that the distance to the nearest pickuplocation dominates on other features for almost all δ. Based onthis observation, we introduce the policy nearest neighbor ornone, a policy with computational complexity O(L 3 ) in manycases of interest. We show that this policy performs considerablybetter that the nearest neighbor (greedy) policy, and reachesthe optimum for some δ.

    The employment of power lines for communications (PLC) has been theorized almost a century ago; although the physicalmedium is not meant for data transmission, recent technical developments pushed the capacity boundary much higher thanexpected, allowing to consider PLC for new applications as the one considered in this contribution, i.e., as a solution for smallcell back/front-hauling. In principle, back-hauling for cellular networks via PLC is very attractive given how pervasive thepower line infrastructure is. Telecom operators are looking for solutions that can handle the traffic increase which is doublingevery year. This calls for improvements of both cellular systems and front-hauling technologies that have to bridge the radionetwork with the core network. Small cells are currently advocated as the solution to spatially fragment the network and offerhigh capacity in densely populated areas; this is also due to the availability of spectrum at high frequency (mmWave links)which inherently offers large bandwidth but forces the cells to become smaller due to the short distance coverage. Therefore,it appears that mobile operators may eventually have to deploy an order of magnitude more (small) cells compared to existingnetworks having macro cells. This translates in a high density cellular network that poses more challenges for the back-haul.

    Power Line Communications (PLC) have been extensively deployed both for in-home high speed networking and for smart grid operation management. In this latter context, PLC are used as a mean of controlling and monitoring the power flow of the grid. They enable the exange of information among devices as meters as well as monitoring/control devices and switches. A fundamental requirement is the knowledge of the network topology, which might not be complete or might not properly track the topological changes due to, for instance, the commutation of power switches. In this work, we present a novel method to derive the topology of a distribution network that exploits the capability of PLC modems to measure the network admittance, and we report the most significant results.

    This paper focuses on MIMO Power Line Communication (PLC) to provide increased performance. In MIMO PLC,appropriate coupling methods are necessary in order to enable the effective injection of the signal through the PLCchannel [1]. In the literature, different kind of couplers are proposed [2],[3]. In this paper, we want to characterize inan analytic way strengths and weaknesses of each coupler design (topology) from an electrical circuit perspective. Wedwell on the description and analysis of the three main and common configurations used for the MIMO couplers: star (S),triangle (∆) and T. For each configuration, we study different connection formats for the input generators and output loads:star, triangle and T. Furthermore, we consider MIMO 2×3, 2×4, 3×3, 3×4 architectures, where the fourth received signal isreferred to as common mode signal.The purpose in this study is to clearly define the equations that describe the output signals as a function of the inputsignals and the impedances present in the circuit. This is achieved analyzing the transfer function of the circuit under survey.A model is presented to be able to identify how much the nonidealities of components, such as, uncoupling/protectiondevices and filters, affect the coupling and cross coupling between signals. All these components add, inside the transmissionchain, undesired effects in the signal of interest. Our aim is to define a procedure that, knowing the characteristics of thesenonideal components, allows us to compensate this effects working on circuit parts and signals.Moreover, the effect of the line impedance variation on the coupled voltage is investigated. This is an important aspectsince the line impedance may have a time variant behavior as a result of network loads that are time variant [4]. In particular,we consider the impedance mismatch problem [5] under a source load constraint with distinct coupler topologies: star,triangle and T.Finally, a comparison of the best combination of TX-RX coupler configurations is carried out.

    Abstract:Impedance matching plays an important role in a power-line-communication system. We investigate the effect on the signal-to-noise ratio at the receiver and on the system capacity of three different impedance matching criteria at the transmitter, assuming broad-band communication. We show that optimal impedance matching shall maximize the amplitude of the signal voltage at the channel input port. Since the line impedance exhibits highly frequency-dependent behavior, simplified impedance matching criteria are also proposed.

    This article deals with power line communication (PLC) in the context of invehicle data networks. This technology can provide high-speed data connectivity via the exploitation of the existing power network, with clear potential benefits in terms of cost and weight reduction. The focus is on two scenarios: an electric car (EC) and a cruise ship. An overview of the wiring infrastructure and the network topology in these two scenarios is provided. The main findings reported in the literature related to the channel characteristics are reported. Noise is also assessed with emphasis on the EC context. New results from the statistical analysis of measurements made in a compact EC and in a large cruise ship are also shown. The channel characteristics are analyzed in terms of average channel gain (ACG), delay spread (DS), coherence bandwidth (CB), and achievable transmission rate. Finally, an overall comparison is made, highlighting similarities and differences while taking into account the conventional combustion engine car and the largely investigated in-home scenario.

    With the emergence of the internet of things (IoT) and participatory sensing (PS) paradigms trustworthiness of remotely sensed data has become a vital research question. In this work, we present the design of a trusted sensor, which uses physically unclonable functions (PUFs) as anchor to ensure integrity, authenticity and non-repudiation guarantees on the sensed data. We propose trusted sensors for mobile devices to address the problem of potential manipulation of mobile sensors' readings by exploiting vulnerabilities of mobile device OS in participatory sensing for IoT applications. Preliminary results from our implementation of trusted visual sensor node show that the proposed security solution can be realized without consuming significant amount of resources of the sensor node.

    This work explores the benefits in terms of energy efficiency that can be provided by device-to-device (D2D) communications in cellular systems. Analyzing a large cellular network using stochastic geometry, considering Nakagami fading and realistic system parameters, we explore the reduction that can be achieved in network power consumption, and the impact this reduction has on the performance of cellular users. When the network is not fully loaded, switching some cellular users into D2D mode results in a significant reduction of the network power consumption while the overall network throughput is maintained. Furthermore, it is observed that the impact of the reduction in the inter-cell interference arising from switching cellular users to D2D mode surpasses that from the new non-orthogonal transmissions. This translates into a slight improvement in the users’ rates. Both analytical and simulation results are provided.

    The high amount of applications to be implemented in the Smart Grid requires bi-directional connectivity between a multitude of nodes with a reliable, high speed, low latency, energy efficient and cost effective communication technology. Power line communication (PLC) has the potentiality to meet the requirements. Indeed, there exists space for PLC technology improvements and to overcome the challenges mostly due to a hostile communication medium. There are two considered frequency spectra: a narrowband (3-500 kHz) spectrum and a broad band (1.8-86 MHz) spectrum that are exploited by current technology. In this paper, we discuss the usage of these spectra both in LV and MV networks, highlighting pros and cons and advocating the realization of an adaptive technology that can cognitively make the best usage of available resources so that the requirements of reliability, latency and coverage can be met.

    [BibTeX] [Abstract] [Download PDF]

    Batteries are extensively used as small to medium range energy storage devices in smart grids. The estimation of the internal states of the batteries such as state-of-charge (SoC) is critical to provide consistent and efficient energy storagecapabilities for the grids. In general, the electrochemical batteries are represented by non-linear mathematical models. Hence, the non-linear filters such as the extended Kalman filter (EKF), cubature Kalman filter (CKF) and particle filters are widely used for the battery state estimation. However, the non-linearfilters are complex compared to the linear filters such as the Kalman filter. The non-linear battery model considered in this paper has an inherent linear sub structure. Hence, we propose a mixed Kalman cubature filter to exploit the inherent linearity to achieve better estimation results with a decreased complexity. The proposed filter uses the Kalman filter and the 3rd degree spherical radial cubature rule to calculate the first and second order moments of the linear and non-linear components, respectively, and subsequently, to estimate the SoC of the batteries. The experimental results show that the proposed filter performs better than the EKF and CKF. Further, the computational complexity of the proposed filter is less than the computational complexity of the CKF. Under the chosen conditions, the proposed filter achieves the average mean square error of approximately 1.1% where as the CKF and EKF achieves 1.3% and 1.5%, respectively with the maximum SoC.

These models allow to quickly develop and test new devices, allowing a considerable saving in time and costs. The aim of this paper is to assess the channel properties and to categorize the most common channel modeling strategies, highlighting strengths and weaknesses. The thorough knowledge of the properties and relations between the most representative channel metrics allowed the development of a novel top-down synthetic channel model. Results are provided concerning different available measurement databases, carried out in different countries, and comparing the experimental measure with the simulated channels. The focus is on broadband low and medium voltage lines, for both indoor and outdoor scenarios.

Indeed, there exists space for PLC technology improvements and to overcome the challenges mostly due to a hostile communication medium. There are two considered frequency spectra: a narrowband (3-500 kHz) spectrum and a broad band (1.8-86 MHz) spectrum that are exploited by current technology. In this paper, we discuss the usage of these spectra both in LV and MV networks, highlighting pros and cons and advocating the realization of an adaptive technology that can cognitively make the best usage of available resources so that the requirements of reliability, latency and coverage can be met.

    Time synchronization provides the basis for several applications in wireless sensor networks but the limited memory and computational power, and the use of low precision oscillators make the task of time synchronization non-trivial. In this demonstration, we present a novel time synchronization scheme that is based on time series analysis. To provide a general model for the practical behavior of low precision oscillators, autoregressive integrated moving average models are explored. Based on the analysis of experimental data, an autoregressive integrated model (ARI (1,1)) is derived. Unlike the resource hungry Kalman filter based formulations, the proposed scheme is resource eefficient as it results in simple linear regression processing. Experiments are performed on real sensor devices including Zolertia and TelosB, where an accuracy below 1 clock tick is achieved.

    Generally, resource-awareness plays a key role in wireless sensor networks due the limitedcapabilities in processing, storage and communication. In this paper we present a resource-aware cooperativestate estimation facilitated by a dynamic cluster-based protocol in a visual sensor network (VSN). The VSNconsists of smart cameras, which process and analyze the captured data locally. We apply a state estimationalgorithm to improve the tracking results of the cameras. To design a lightweight protocol, the final aggregationof the observations and state estimation are only performed by the cluster head. Our protocol is based on amarket-based approach in which the cluster head is elected based on the available resources and a visibilityparameter of the object gained by the cluster members. We show in simulations that our approach reduces thecosts for state estimation and communication as compared to a fully distributed approach. As resourceawarenessis the focus of the clusterbased protocol we can accept a slight degradation of the accuracy on theobject’s state estimation by a standard deviation of about 1.48 length units to the available ground truth.

    We present an ultra-wideband (UWB) sensor network,deployed for aircraft applications. Off-the-shelf IEEE802.15.4-2011 UWB compliant transceivers are, so far, onlyused for localization purposes. Thus, we modify transceiverconfigurations to enable data communication and realize a timedivision MAC scheme. Shadowing and the impact of passengermobility are experimentally evaluated. Furthermore, channelattenuation and small-scale fading is analyzed, considering emptyand occupied cabin cases and different node deployment positions.

    There is a clear trend in camera networks towardsenhanced functionality and flexibility, and a fixed staticdeployment is typically not sufficient to fulfill these increasedrequirements. Dynamic network reconfiguration helps to optimizethe network performance to the currently required specifictasks while considering the available resources. Although severalreconfiguration methods have been recently proposed, e.g., formaximizing the global scene coverage or maximizing the imagequality of specific targets, there is a lack of a general frameworkhighlighting the key components shared by all these systems.In this paper we propose a reference framework for networkreconfiguration and present a short survey of some of the mostrelevant state-of-the-art works in this field, showing how they canbe reformulated in our framework. Finally we discuss the mainopen research challenges in camera network reconfiguration.

In an exper-iment with 50 devices in an industrial environment cooperativerelaying increases the end-to-end transmission reliability formulti-hop links to nearly 100 % while reducing the average packetdelay. We suggest how to include relay selection in the routediscovery process of ad hoc routing protocols such as Ad hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing(DSR) and perform two experiments.

    This paper presents the extension of the simulator VSNsim to enable the simulation of hybrid camera networks in the field of coordination and control algorithms. A hybrid camera network combines mobile and static cameras. Thus, mobile cameras in form of autonomously moving robots are added to the existing static cameras of VSNsim. Furthermore, priorities can be assigned to rooms in the simulated environment in order to focus monitoring to dedicated areas.

    With the help of smart metering valuable information of the appliance usage can be retrieved. In detail, non-intrusive load monitoring (NILM), also called load disaggregation, tries to identify appliances in the power draw of anhousehold. In this paper an unsupervised load disaggregation approach is proposed that works without a priori knowledge aboutappliances. The proposed algorithm works autonomously in realtime.

    Time synchronization is challenging in wireless sensor networksdue to the use of low-precision oscillators and thelimited computational capacity of resources limited sensornodes. While several schemes exist, the performance analysisof a majority of them is based on simulations and failto capture key features of real world deployments. Thispaper explores the use of autoregressive integrated movingaverage models to provide a general clock model for sensornodes with low precision oscillators and limited computationalpower. Based on measurements with o-the-shelfsensor devices Z1, an autoregressive integrated model fortime synchronization is proposed. We derive a synchronizationscheme (ARI-Sync) based on this model and compareit against the well known Flooding Time SynchronizationProtocol (FTSP) observing signicantly improved accuracy,roughly doubling the resynchronization period of Z1 nodesfor a typical wireless sensor network application.

    Device-to-device (D2D) communications is a promising candidate for increasing the throughput of cellular systems towards 5G. Its current consideration for inclusion in LTE-A is attracting a lot of research interest, including work on mode selection, bandwidth allocation, and power control. Some consider the uplink for D2D operation while others focus on operation over the downlink. It is still unclear, however, which link is preferable for D2D operation. This paper addresses this issue focusing on the outage performance of D2D receivers. We use stochastic geometry tools for our analysis, considering realistic system parameters and Nakagami fading. We find that the interference from the cellular system on the downlink, which is correlated over consecutive time slots, favors underlay D2D operation, resulting in a lower outage probability for the D2D transmissions.

    When visual sensor networks are composed of cameras which can adjust the zoom factor of their own lens, one must determine the optimal zoom levels for the cameras, for a given task. This gives rise to an important trade-off between the overlap of the different cameras’ fields of view, providing redundancy, and image quality. In an object tracking task, having multiple cameras observe the same area allows for quicker recovery, when a camera fails. In contrast having narrow zooms allow for a higher pixel count on regions of interest, leading to increased tracking confidence. In this paper we propose an approach for the self-organisation of redundancy in a distributed visual sensor network, based on decentralised multi-objective online learning using only local information to approximate the global state. We explore the impact of different zoom levels on these trade-offs, when tasking omnidirectional cameras, having perfect 360-degree view, with keeping track of a varying number of moving objects. We further show how employing decentralised reinforcement learning enables zoom configurations to be achieved dynamically at runtime according to an operator’s preference for maximising either the proportion of objects tracked, confidence associated with tracking, or redundancy in expectation of camera failure. We show that explicitly taking account of the level of overlap, even based only on local knowledge, improves resilience when cameras fail. Our results illustrate the trade-off between maintaining high confidence and object coverage, and maintaining redundancy, in anticipation of future failure. Our approach provides a fully tunable decentralised method for the self-organisation of redundancy in a changing environment, according to an operator’s preferences

    Generally, resource-awareness plays a key role in wirelesssensor networks due the limited capabilities in processing, storage andcommunication. In this paper we present a resource-aware cooperative stateestimation facilitated by a dynamic cluster-based protocol in a visual sensornetwork (VSN). The VSN consists of smart cameras, which process and analyze thecaptured data locally. We apply a state estimation algorithm to improve thetracking results of the cameras. To design a lightweight protocol, the finalaggregation of the observations and state estimation are only performed by thecluster head. Our protocol is based on a market-based approach in which thecluster head is elected based on the available resources and a visibilityparameter of the object gained by the cluster members. We show in simulationsthat our approach reduces the costs for state estimation and communication ascompared to a fully distributed approach. As resource-awareness is the focus ofthe cluster-based protocol we can accept a slight degradation of the accuracyon the object’s state estimation by a standard deviation of about 1.48 lengthunits to the available ground truth.

    [BibTeX] [Abstract]

    The precision of synchronization algorithms based on the theory of pulse-coupled oscillators is evaluated on FPGA-based radios for the first time. Measurements show that such algorithms can reach precisions in the low microsecond range when being implemented in the physical layer. Furthermore, we propose an algorithm extension accounting for phase rate deviations of the hardware and show that an improved precision below one microsecond is possible with this extension in the given setup. The resulting algorithm can thus be applied in ad hoc wireless systems for fully distributed synchronization of transmission slots or sleep cycles, in particular, if centralized synchronization is impossible.

    Smart cameras perform on-board image analysis, adapt their algorithms to changes in their environment, and collaborate with other networked cameras to analyze the dynamic behavior of objects. A proposed computational framework adopts the concepts of self-awareness and selfexpression to more efficiently manage the complex tradeoffs among performance, flexibility, resources, and reliability.

    Power line communications (PLC) are affected bysevere noise. In the in-home scenario, the household appliancesare the main sources of noise, when they are fed and running,as they inject noise in the frequencies where PLC operate.This work presents a methodology for the characterizationof the noise generated by devices connected to the power grid.The methodology is applied to study a number of householdappliances. The study enables to a) identify the most noisydevices from which PLC transceivers should be kept far away, b)characterize the noise both in the time and the frequency domain,c) address the definition of noise limits from an EMC regulatorperspective, and d) quantify the amplitude of the impulsive noisethat may damage the analog front-end of the PLC transceiver.The work addresses both the noise during the normal operatingconditions of the household appliances, and the noisegenerated during transients, i.e., when the device is connected,disconnected, switched on or off. In this respect, it is shown thattransients may lead to noise spikes that exceed tens of Volts.

    We analyze the performance of an interferencelimited, decode-and-forward, cooperative relaying system that comprises a source, a destination, and N relays, placed arbitrarily on the plane and suffering from interference by a set ofinterferers placed according to a spatial Poisson process. In each transmission attempt, first the transmitter sends a packet; subsequently, a single one of the relays that received the packet correctly, if such a relay exists, retransmits it. We considerboth selection combining and maximal ratio combining at thedestination, Rayleigh fading, and interferer mobility.We derive expressions for the probability that a single transmission attempt is successful, as well as for the distribution of the transmission attempts until a packet is transmitted successfully. Results provide design guidelines applicable to a wide rangeof systems. Overall, the temporal and spatial characteristics of the interference play a significant role in shaping the system performance. Maximal ratio combining is only helpful when relays are close to the destination; in harsh environments, havingmany relays is especially helpful, and relay placement is critical; the performance improves when interferer mobility increases; and a tradeoff exists between energy efficiency and throughput.

    We study the self-organising behaviour of socio-economic distributed smart camera networks, those which use strategies based on social and economic knowledge to target communication activity efficiently. We compare homogeneous configurations, when cameras use the same strategy, with heterogeneous configurations, when cameras use different strategies. Our first contribution is to establish that static heterogeneity leads to new outcomes which are more efficient than those possible with homogeneity. Next, two forms of dynamic heterogeneity are investigated: non-adaptive mixed strategies, and adaptive strategies which learn online. Our second contribution is to show that mixed strategies offer Pareto efficiency consistently comparable with the most efficient static heterogeneous configurations. Since the particular configuration required for high Pareto efficiency in a scenario will not be known in advance, our third contribution is to show how decentralised online learning can lead to more efficient outcomes than the homogeneous case, and in some cases, than all other evaluated configuration types. Our fourth contribution is to show that online learning typically leads to outcomes more evenly spread over the objective space. Our results provide insight into the relationship between static, dynamic and adaptive heterogeneity in decentralised systems, suggesting that all have a key role to play towards efficient self-organisation.

    Orientation estimation is considered as an important task in many subsequent pattern recognition and image enhancement systems. In a noisy environment, the gradient-based estimator provides poor results. A pre-smoothing Gaussian function with an appropriate scale is conventionally used to get improved gradients. Later on, a family of pre-smoothing Gaussian functions with a range of scales is employed for estimation, this is referred to as multi-scale orientation estimator. To provide groundwork for comparison, a more formal framework of multi-scale orientation estimation, based on scale-space axioms, in spatial domain is presented. Then for improvement purposes a Fourier domain approach, where directional filter bank (DFB) structure is embedded in multi-scale orientation estimation framework, is proposed. This is referred to as multi-scale DFB approach. The paper presents the comparison work for estimation of local orientations using multi-scale approaches both in spatial and Fourier domain. In the Fourier-domain approach, two linear combinations are deployed, one across the directional image, and the other across the scales. This is opposed to only one linear combination across the scales, used in simple spatial domain techniques. Further more, the DFB-based Fourier domain approach extracts the best local orientation by comparing and contrasting all possible orientations with their respective strength measures. The strength measure used in Fourier method is based on local variance, free from inaccurate gradient calculation. Simulations are conducted over noisy test images as well as real fingerprints. Our objective results indicate that multi-scale Fourier domain approach always yields better estimates at variable level of noise as compared to stand alone multi-scale spatial domain approaches. The improvements made by Fourier domain estimate can largely be attributed to the use of double linear combination both across the directional bands and across the scales.

    We specify and evaluate a protocol for cooperative relay communications in wireless networks targeted for low-budget and energy-constrained off-the-shelf hardware. The protocol located at the Medium Access Control (MAC) layer integrates radio resource reservation, relay selection, and packet flow. Performance is evaluated with different parameters, such as node density, channel coherence time, and data packet size. Higher network-wide reliability and throughput compared to noncooperative protocols can be achieved in dense networks and unreliable channels. At the same time, throughput does not degrade in sparse networks or good channel conditions.

    The use of multiple small-scale UAVs to support first responders in disaster management has become popular because of their speed and low deployment costs. We exploit such UAVs to perform real-time monitoring of target areas by fusing individual images captured from heterogeneous aerial sensors. Many approaches have already been presented to register images from homogeneous sensors. These methods have demonstrated robustness against scale, rotation and illumination variations and can also cope with limited overlap among individual images.In this paper we focus on thermal and visual image registration and propose different methods to improve the quality of interspectral registration for the purpose of real-time monitoring and mobile mapping. Images captured by low-altitude UAVs represent a very challenging scenario for interspectral registration due to the strong variations in overlap, scale, rotation, point of view and structure of such scenes. Furthermore, these small-scale UAVs have limited processing and communication power. The contributions of this paper include (i) the introduction of a feature descriptor for robustly identifying corresponding regions of images in different spectrums, (ii) the registration of image mosaics, and (iii) the registration of depth maps. We evaluated the first method using a test data set consisting of 84 image pairs. In all instances our approach combined with SIFT or SURF feature-based registration was superior to the standard versions. Although we focus mainly on aerial imagery, our evaluation shows that the presented approach would also be beneficial in other scenarios such as surveillance and human detection. Furthermore, we demonstrated the advantages of the other two methods in case of multiple image pairs.

    When faced with the task of designing and implementing a new self-aware and self-expressive computing system, researchers and practitioners need a set of guidelines on how to use the concepts and foundations developed in the Engineering Proprioception in Computing Systems (EPiCS) project. This report provides such guidelines on how to design self-aware and self-expressive computing systems in a principled way. We have documented different categories of self-awareness and self-expression level using architectural patterns. We have also documented common architectural primitives, their possible candidate techniques and attributes for architecting self-aware and self-expressive systems. Drawing on the knowledge obtained from the previous investigations, we proposed a pattern driven methodology for engineering self-aware and self-expressive systems to assist in utilising the patterns and primitives during design. The methodology contains detailed guidance to make decisions with respect to the possible design alternatives, providing a systematic way to build self-aware and self-expressive systems. Then, we qualitatively and quantitatively evaluated the methodology using two case studies. The results reveal that our pattern driven methodology covers the main aspects of engineering self-aware and self-expressive systems, and that the resulted systems perform significantly better than the non-self-aware systems.

    Strict reliability and delay requirements of factory monitoring and control applications pose challenges for wireless communications in dynamic and cluttered industrial environments. To reduce outage in such fading-rich areas, cooperative relays can be used to overhear source-destination transmissions and forward data packets that a source fails to deliver. This paper presents the results of an experimental study of selective cooperative relaying protocols that are implemented in off-the-shelf IEEE 802.15.4-compatible devices and evaluated in an industrial production plant. Three practical relay update schemes, which define when a new relay selection is triggered, are investigated: 1) periodic; 2) adaptive; and 3) reactive relay selections. The results show that all relaying protocols outperform conventional time diversity retransmissions in delivery ratio and number of retransmissions for packet delivery. Reactive selection provides the best overall delivery ratio of nearly 99% over the tested network. There is a tradeoff, however, between achievable delivery ratio and required selection overhead. This tradeoff depends on protocol and network parameters, and is studied via protocol emulation using empirical channel values.

    This paper provides an overview of power line communication (PLC) applications, challenges and possible evolution. Emphasis is put on two relevant aspects: a) channel characterization and modeling, b) filter bank modulation for spectral efficient transmission. The main characteristics of both the indoor channel (in-home, in-ship, in-car) and the outdoor low voltage and medium voltage channels are reported and compared. A simple approach to statistically model the channel frequency response (CFR) is described and it is based on the generation of a vector of correlated random variables. To overcome the channel distortions, it is shown that filter bank modulation can provide robust performance. In particular, it is shown that the sub-channel spectral containment of filtered multitone modulation (FMT) can provide high notching capability and spectral efficiency. Reduced complexity can be obtained with a cyclic filter bank modulation approach that we refer to as cyclic block FMT modulation (CB-FMT) which still provides higher spectral flexibility/efficiency than OFDM.

    Households account for a notable amount of overall energy consumption, thus they represent a field where it is possible to potentially obtain great energy savings. Energy management systems (EMSs) can be used to this end. They allow for monitoring and managing energy consumption of household appliances or renewable energy sources, as well as making users aware of their energy consumptions. User awareness has been shown to yield up to 20% of energy savings. In this paper, we propose a design procedure for the communication network of a home energy management system (HEMS). We discuss design choices of a HEMS which is currently under development within the MONERGY project, an initiative aiming at boosting the energy awareness of households in two regions: Carinthia (Austria) and Friuli-Venezia Giulia (Italy). Although the system is tailored to the peculiarities of the regions, we believe that the proposed design guidelines can be of help for engineers of EMSs. In particular, the work addresses key issues of the communication network requirements such as coverage, topology, number of nodes, metering resolution and communication technologies. Furthermore, real world tests of wireless and power line communication (PLC) technologies are carried out to see whether existing HEMSs satisfy the communication network requirements.

    shown to yield up to 20% of energy savings. In this paper, we propose a design procedure for the communication network of a home energy management system (HEMS).
    We discuss design choices of a HEMS which is currently under
    development within the MONERGY project, an initiative aiming
    at boosting the energy awareness of households in two regions:
    Carinthia (Austria) and Friuli-Venezia Giulia (Italy). Although
    the system is tailored to the peculiarities of the regions, we
    believe that the proposed design guidelines can be of help for
    engineers of EMSs. In particular, the work addresses key issues
    of the communication network requirements such as coverage,
    topology, number of nodes, metering resolution and communication technologies. Furthermore, real world tests of wireless and
    power line communication (PLC) technologies are carried out to
    see whether existing HEMSs satisfy the communication network
    requirements.

    In this paper, we propose strategies for merging occupancy probabilities of target existence in multi-UAV cooperative search. The objective is to determine the impact of cooperation and type of information exchange on search time and detection errors. To this end, we assume that small-scale UAVs (e.g., quadrotors) with communication range limitations move in a given search region following pre-defined paths to locate a single stationary target. Local occupancy grids are used to represent target existence, to update its belief with local observations and to merge information from other UAVs. Our merging strategies perform Bayes updates of the occupancy probabilities while considering realistic limitations in sensing, communication and UAV movement—all of which are important for small-scale UAVs. Our simulation results show that information merging achieves a reduction in mission time from 27% to 70% as the number of UAVs grows from 2 to 5.

    [BibTeX] [Abstract] [Download PDF]

    Several non-linear state estimation methods such as extended Kalman filter, cubature Kalman filter, and unscented Kalman filter are used to track objects in visual sensor networks. These conventional non-linear state estimation methods require the accurate knowledge of the object’s initial conditions, process and measurement models, and corresponding noise characteristics. Often, the object trackers used in a visual sensor networks may not be provided with this knowledge. In this work, we propose a square root cubature H¿ information Kalman filter (SCHIF) based distributed object tracking algorithm. The H¿ method requires neither the exact knowledge of noise characteristic nor accurate process model. The information filters can be used without the knowledge of accurate initial conditions and it also makes the measurement update step computationally less complex in the distributed process. Finally, the square root version makes the filter numerically stable. Furthermore, the cameras in the network exchange their local estimates with other cameras. In the last step, the cameras fuse the received local estimates to obtain a global estimate of the object. Hence, the proposed method constitutes a more robust and efficient solution for the targeted application compared to the traditional methods.

    Wireless sensor networks (WSN) are an attractive platform for cyber physical systems. A typical WSN applications composed of different tasks which need to be scheduled on each sensor node. However, the severe energy limitations pose a particular challenge for developing WSN applications, and the scheduling of tasks has typically a strong influence on the achievable performance and energy consumption. In this paper we propose a method for scheduling the tasks using cooperative reinforcement learning (RL) where each node determines the next task based on the observed application behavior. In this RL framework we can trade the application performance and the required energy consumption by a weighted reward function and can therefore achieve different energy/performance results of the overall application. By exchanging data among neighboring nodes we can further improve this energy/performance trade-off. We evaluate our approach in an target tracking application.Our simulations show that cooperative approaches are superior to non-cooperative approaches for this kind of applications.Index Terms—Reinforcement learning, tasks scheduling, energy efficiency, wireless sensor networks, target tracking.

The protocol is robust against the stochastic nature of the wireless channel and provides compensations against random delays. Results show convergence within a few cycles to a synchronization precision of few hundred microseconds without casting off the control overhead. The performance is compared to that of the standard implementation of the Flooding Time Synchronization Protocol (FTSP).

    This paper shows the productivity of grid-connected photovoltaic systems, to plan future investments in the region around Klagenfurt, Austria. To evaluate the usage of grid-connected PV systems, a methodology based on mainly three factors is presented. These factors are yield factor, capacity factor and cost of energy. The analysis is done by a model based on monitored PV data and meteorological data in an interval of 15 minutes. Meteorological data was recorded from May 2013 until July 2014 with a lack of data from September 2013 until January 2014. By analyzing the collected data, it is found that the daily average solar energy in Klagenfurt was 6613Wh/m2 in the time of research. The results of the research show that future investments in grid-connected PV systems in Klagenfurt can be profitable. The yield factor over the time of research (293 days) is 1263.4kWh/kWp, whereas the capacity factor of the proposed system is 17.97%. The cost of energy is found to be 0.2348€/kWh. This is a satisfactory result compared with values of other European counties.

Meteorological data was recorded from May 2013 until July 2014 with a lack of data from September 2013 until January 2014. By analyzing the collected data, it is found that the daily average solar energy in Klagenfurt was 6613Wh/m2 in the time of research. The results of the research show that future investments in grid-connected PV systems in Klagenfurt can be profitable. The yield factor over the time of research (293 days) is 1263.4kWh/kWp, whereas the capacity factor of the proposed system is 17.97%. The cost of energy is found to be 0.2348€/kWh. This is a satisfactory result compared with values of other European counties.},

    This paper presents a free and open source micro- grid simulation framework for better understanding of power flow behavior in smart microgrids with renewable sources. It is able to simulate grid-connected or standalone microgrids with solar, wind or other renewable energy sources. The proposed software calculates the power generated by each source in the microgrid and can conduct a power flow analysis. This software is helpful for optimal placement of distributed generation units in a micro grid. The software RAPSim is designed for use in science and classroom with a simple to use graphical interface. It is an easily extendable framework that supports users in implementation of their own gridobject models and grid controlling algorithms.

    Images captured in camera networks are potentially privacy sensitive and therefore need protection. A critical aspect is where protection is applied – after transmission at the data center or preferably already on the camera. In this work we take on-camera protection a step further and propose to make privacy protection and security inherent features of the image sensing unit. Already within the camera we realize strong separation between components that have access to raw image data and those that do not need raw data access. Our approach is based on the custom-designed TrustEYE.M4 prototype of a secure sensing unit. We demonstrate the feasibility of sensor-level privacy protection with a cartoon-like effect based on mean shift filtering.

    This paper presents design and evaluation of grid-connected photovoltaic system in Oman. Hourly global and diffuse solar radiation data as well as ambient temperature data for one year time have been used. REPS.OM software is used to design the proposed system which is a 1.4 kWp PV system. The designed system is implemented practically and experimentally tested for six months to check the technical and economic feasibility. The system is evaluated using two technical criteria which are capacity and yield factors. In addition, system feasibility is evaluated in terms of the cost of energy and payback period. The results showed that the capacity and yield factors for the proposed system are 21% and 1875 kWh/kWp/year respectively. In the meanwhile, the cost of the energy generated and the payback period of the proposed system are 0.045 USD/kWh and 11years, respectively. This study contains valuable experiment data for researchers and investors who are interested in photovoltaic system investment in Oman and nearby desertic zons

    We investigate the statistics of the number of time slots T that it takes a packet to travel through a chain of wireless relays. Derivations are performed assuming an interference model for which interference possesses spatiotemporal dependency properties. When using this model, results are harder to arrive at analytically, but they are more realistic than the ones obtained in many related works that are based on independent interference models.First, we present a method for calculating the distribution of T. As the required computations are extensive, we also obtain simple expressions for the expected value E[T] and variance Var[T]. Finally, we calculate the asymptotic limit of the average speedof the packet. Our numerical results show that spatiotemporal dependence has a significant impact on the statistics of the travel time T. In particular, we show that, with respect to the independent interference case, E[T] and Var[T] increase, whereasthe packet speed decreases.

    Protocols for neighbor cardinality estimation can be used by a node in an ad hoc or sensor network to obtain a fast approximation of the number of nodes in its radio range. While the performance of such estimators was studied via simulations and mathematical analysis, we show here for the first time a proof-of-concept and performance test with an implementation on low-power wireless sensor devices. We illustrate the challenges of implementing the recently proposed Multi-Feedback Estimator (MFE) on Z1 devices. Exper- imental results show that – with certain computational improve- ments – MFE can perform faster than simple neighbor counting for scenarios with many nodes or relaxed accuracy requirements.

    An important building block in cooperative diversity is relay selection, which has to ensure that a well-suited node is employed as a relay. The required coordination among nodes causes signaling overhead, which in turn can significantly devalue the performance benefits gained by cooperative diversity. A relay update policy defines when a new relay is selected; it can balance the tradeoff between performance and overhead. This tradeoff is studied using mathematical methods. We consider three relay selection schemes, i.e., permanent, reactive, and adaptive, which have different relay update rules. We develop an analytical framework using semi-Markov processes to evaluate the throughput and energy efficiency of cooperative automatic repeat request (ARQ) protocols in time-correlated multipath fading channels. Results reveal potential performance gains of different selection schemes under various conditions. The reactive and adaptive schemes make use of better suited relays due to frequent selections. If their selection overhead, however, is significant, a permanent relay can achieve higher throughput due to negligible overhead. The impact of temporal correlation of fading channels on throughput and energy efficiency is also shown. These insights can be applied for development of cooperative communication protocols.

    Networks of micro aerial vehicles (MAVs) equipped with various sensors are increasingly used for civil applications, such as monitoring, surveillance, and disaster management. In this article, we discuss the communication requirements raised by applications in MAV networks. We propose a novel system representation that can be used to specify different application demands. To this end, we extract key functionalities expected in an MAV network. We map these functionalities into building blocks to characterize the expected communication needs. Based on insights from our own and related real-world experiments, we discuss the capabilities of existing communications technologies and their limitations to implement the proposed building blocks. Our findings indicate that while certain requirements of MAV applications are met with available technologies, further research and development is needed to address the scalability, heterogeneity, safety, quality of service, and security aspects of multi-MAV systems.

    The availability of PV systems is discussed to determine the optimum availability at which standalone PV systems must be designed. Optimization methods and PV systems software, such as HOMER and PV.MY, were used for this purpose. Six PV systems with six availability levels were analyzed, in terms of wasted energy, cost of energy, battery usage, and power shortages, using real meteorological data. Results show that PV systems with 99% availability are recommended, because of their high reliability and favorably wasted energy.

    Distributed generation (DG) is an important element to be considered in distribution planning since it plays a major role in stability and power quality improvement. This paper presents a new method for determining optimal sizing and placement of DG in a distribution system. A multi-objective function is formed to minimize the total losses, average total voltage harmonic distortion, and voltage deviation in the distribution system. The improved gravitational search algorithm (IGSA) is proposed as an optimization techniques and its performance is compared with other optimization techniques such as particle swarm optimization (PSO) and GSA. The load flow algorithm from MATPOWER and harmonic load flow was integrated in MATLAB environment to solve the proposed multi-objective function. Finally, the proposed algorithm is tested on the radial 69-bus distribution system with three case studies. The results show that the IGSA performs better than PSO and GSA by giving the best fitness value and the fastest average elapsed time.

    Visual sensor networks (VSNs) are receiving a lot of attention in research, and at the same time, commercial applications are starting to emerge. VSN devices come with image sensors, adequate processing power, and memory. They use wireless communication interfaces to collaborate and jointly solve tasks such as tracking persons within the network. VSNs are expected to replace not only many traditional, closed-circuit surveillance systems but also to enable emerging applications in scenarios such as elderly care, home monitoring, or entertainment. In all of these applications, VSNs monitor a potentially large group of people and record sensitive image data that might contain identities of persons, their behavior, interaction patterns, or personal preferences. These intimate details can be easily abused, for example, to derive personal profiles.The highly sensitive nature of images makes security and privacy in VSNs even more important than in most other sensor and data networks. However, the direct use of security techniques developed for related domains might be misleading due to the different requirements and design challenges. This is especially true for aspects such as data confidentiality and privacy protection against insiders, generating awareness among monitored people, and giving trustworthy feedback about recorded personal data—all of these aspects go beyond what is typically required in other applications.

    The standard approach of assessing the efficiency of a solar cell is strongly depending on the cell temperature (Tc). The value of Tc is calculated based on solar radiation and ambient temperature values as well as the nominal operating cell temperature (NOCT). NOCT is defined as the temperature element in a solar cell exposed at 800 W/m2 of solar radiation, 20 °C of ambient temperature, and a wind speed of 1?m/s. However, these conditions may vary depending on the climate zone nature. In this research, a new condition called tropical field operation cell temperature (tFOCT) is introduced based on the maximum daily standard climatic parameters under tropical field conditions. These parameters are calculated and justified using generalized extreme value distribution based on the transient conditions of the tropical weather as a unique approach of field value adaptation. The results show that the suitable weather conditions for measuring the tFOCT are 886?W/m2 of solar radiation, 34?°C of ambient temperature, and a wind speed of 3.2 m/s. In addition to that, it is concluded that the recommended tFOCT value is 52.5 °C. Based on these conditions, an enhanced Tc model is proposed and it is found that this model has higher accuracy than the standard model.

    Visual privacy in video-based applications such as surveillance, assisted living or home monitoring is a highly active research topic. It is critical to protect the privacy of monitored people without severely limiting the utility of the system. We present a resource-aware cartooning privacy protection filter which converts raw images into abstracted frames where the privacy revealing details are removed. Cartooning can be applied either to entire images or pre-selected sensitive regions of interest. We provide an adaptation mechanism to our cartooning technique where the operator can easily change the filter intensity. The feasibility of this new approach is demonstrated by its deployment to real-world embedded smart cameras. We evaluate privacy protection and utility of cartooning with the PEViD data set and compare it with the two widely-used privacy filters: blurring and pixelation.

    To solve multi-objective problems, multiple reward signals are often scalarized into a single value and further processed using established single-objective problem solving techniques. While the field of multi-objective optimization has made many advances in applying scalarization techniques to obtain good solution trade-offs, the utility of applying these techniques in the multi-objective multi-agent learning domain has not yet been thoroughly investigated. Agents learn the value of their decisions by linearly scalarizing their reward signals at the local level, while acceptable system wide behaviour results. However, the non-linear relationship between weighting parameters of the scalarization function and the learned policy makes the discovery of system wide trade-offs time consuming. Our first contribution is a thorough analysis of well known scalarization schemes within the multi-objective multi-agent reinforcement learning setup. The analysed approaches intelligently explore the weight-space in order to find a wider range of system trade-offs. In our second contribution, we propose a novel adaptive weight algorithm which interacts with the underlying local multi-objective solvers and allows for a better coverage of the Pareto front. Our third contribution is the experimental validation of our approach by learning biobjective policies in self-organising smart camera networks. We note that our algorithm (i) explores the objective space faster on many problem instances, (ii) obtained solutions that exhibit a larger hypervolume, while (iii) acquiring a greater spread in the objective space.

    We present a novel iterative algorithm for approximating the linear least squares solution with low complexity. After a motivation of the algorithm we discuss the algorithm’s properties including its complexity, and we present theoretical results as well as simulation based performance results. We describe the analysis of its convergence behavior and show that in the noise free case the algorithm converges to the least squares solution.

    A reliable knowledge of cell parameters like the state-of-charge (SoC) is essential for the optimization of battery-powered applications. Usually, during relaxation (the phase of no or low loads) the SoC is determined based on the measurement of the battery’s electro-motive force (EMF). To obtain a reliable measurment, it is required that the battery voltage transient is in a well-relaxed state, which is rarely reached in practice (e.g. due to periodic discharge activities). In this paper, a predictive methodology is presented which is able to forecast the EMF and therewith the SoC already during a not well-relaxed state of the voltage transient. A nonlinear relaxation voltage model is reformulated such that the problem can be treated as a linear least squares estimation problem. Based on this estimation, the performance is evaluated with respect to the following aspects: prediction time, current rate influence, SoC influence, cell-to-cell deviation, or rather aging and temperature effects. Experimental results are presented for a fixed-point implementation of the estimation scheme on a CY8CKIT-050 PSOC5 programmable system on chip. For validation, measurements of 2.25Ah Sanyo UR18650A lithium cells have been used. It is shown that the presented approach offers an improved re-initialization methodology for the Coulomb counting method, and that it clearly outperforms the usual EMF-measurement based SoC determination method.

    The analysis and evaluation of concepts in the research fields of visual sensor networks (VSNs) suffer from the low number of simulation possibilities. In this paper we present a simulator, the VSNsim, dedicated for evaluating control and coordination strategies in VSNs. It is built with the game engine Unity3D and has a very user friendly handling. The algorithms locally running on the sensor nodes of the VSN canbe implemented in C#, JavaScript or Boo. Due to graphical user interface and the 3D implementation, our simulator is a tool that can be intuitively applied and extended to aresearcher’s need.

    We show by means of stochastic geometry that interference dynamics has a strong impact on the performance of cooperative relaying. For both conventional and multi-hop-aware cooperative relaying we show that the packet delivery probability significantly changes with the dependence of interference among the links. Depending on the scenario under consideration, this change could be either an increase or decrease of the packet delivery probability. Especially for multi-hop-aware cooperative relaying, the performance gain is heavily reduced when interference possesses high temporal and spatial dependence.

    [BibTeX] [Abstract]

    Smart cameras allow pre-processing of video data on the camera instead of sending it to a remote server for further analysis. Having a network of smart cameras allows various vision tasks to be processed in a distributed fashion. While cameras may have different tasks, we concentrate on distributed tracking in smart camera networks. This application introduces various highly interesting problems. Firstly, how can conflicting goals be satisfied such as cameras in the network try to track objects while also trying to keep communication overhead low? Secondly, how can cameras in the network selfadapt in response to the behaviour of objects and changes in scenarios, to ensure continued efficient performance? Thirdly, how can cameras organise themselves to improve the overall network’s performance and efficiency? This paper presents a simulation environment, called CamSim, allowing distributed self-adaptation and self-organisation algorithms to be tested, without setting up a physical smart camera network. The simulation tool is written in Java and hence allows high portability between different operating systems. Relaxing various problems of computer vision and network communication enables a focus on implementing and testing new self-adaptation and self-organisation algorithms for cameras to use.

    This article proposes and analyzes a distributed probabilistic selection protocol in which several nodes perform a random access competition on a shared slotted channel. Nodes that are better suited according to some metric are preferred in the random access and are thus selected with high likelihood. Analytical performance studies are made in terms of reliability, message complexity, and delay. The protocol is applied in two case studies: relay communications and load balancing in wireless networks. In relay communications, a node is selected based on its channel state to serve as relay. In load balancing, a node is selected based on its battery charge state to perform a task. Results indicate that selecting nodes based on the observed metric contributes to better performance and longer network lifetime.

    Solutions for time synchronization based on coupled oscillators operate in a self-organizing and adaptive manner and can be applied to various types of dynamic networks. In this demo, we present the actual implementation of our guaranteed self-organizing synchronization algorithm on packet based networks like wireless sensor networks as well as on iPhone devices (by using acoustic signals). The algorithm is purposed for pulse couple oscillators and exploits the interactions between them to guarantee synchronization on arbitrary network topologies. It supports the design of scalable, minimal control toter and energy efficient communication protocols for fully distributed synchronization.

    We analyze the dynamics of interference in a wireless network under a correlated traffic model: A given node increases or decreases its transmission probability if it has transmitted in the preceding time slot. This traffic model is of importance since it resembles part of the behavior of many communication techniques as, e.g., retransmission protocols or cooperative relaying. Results show that the traffic model has high impact on temporal correlation of interference, which has to be considered when designing such techniques.

    [BibTeX] [Abstract] [Download PDF]

    Most state-of-the-art driver assistance systems cannot guarantee that real-time images of object states are updated within a given time interval, because the object state observations are typically sampled by uncontrolled sensors and transmitted via an indeterministic bus system such as CAN. To overcome this shortcoming, a paradigm shift toward time-triggered advanced driver assistance systems based on a deterministic bus system, such as FlexRay, is under discussion. In order to prove the feasibility of this paradigm shift, this paper develops different models of a state-of-the-art and a time-triggered advanced driver assistance system based on multi-sensor object tracking and compares them with regard to their mean performance. The results show that while the state-of-the-art model is advantageous in scenarios with low process noise, it is outmatched by the time-triggered model in the case of high process noise, i.e., in complex situations with high dynamic.

    [BibTeX] [Abstract] [Download PDF]

    This paper investigates the dust effect on the photovoltaic module (multi-crystalline) performance (the output voltage and generated power). The degradation of PV performance due to the deposition of different pollutant types, and accumulation has been investigated. Experiments concerning the effects of air pollutants (red soil, ash, sand, calcium carbonate, and silica) on the power generated are conducted and analyzed. The results show that the reduction in PV voltage and power is strongly depending on pollutant type, and deposition level. The results show that the ash pollutant is the most effecting dust particle on the PV module voltage as compared to the other used dust pollutants where high reduction in PV voltage (25%) is recorded when the ash pollutant is used.

    A visual sensor network (VSN) consists of resource- limited camera nodes which process the captured image data locally and collaborate with other cameras over a wireless network. The configuration of the network is a very important task in VSNs in order to adapt the available resources to the current requirements of the application. We focus on coverage and task assignment as a key configuration problem for VSNs. Due to rapid changes in the VSN’s environment, a dynamic and online reconfiguration is highly needed. In this paper we introduce and evaluate a fast and distributed resource-aware reconfiguration algorithm. Our approach is based on simple optimization primitives to find good approximations and to keep the required data transfer in the VSN small. We analyze the communication complexity and compare our algorithm with a centralized configuration approach based on several scenarios with different complexity. Our experiments show that we can achieve the same configuration quality as with the centralized approach in almost all cases.

    Fusing multiple views of different cameras in a visual sensor network (VSN) require the calculation of a consensus. As a result we are able to overcome the uncertainties from the tracking algorithm and physical constraints in the observed environment. This paper addresses the topic of reaching a consensus within VSN of calibrated or uncalibrated cameras. In contrast to several proposed techniques, where the consensus is calculated on all cameras simultaneously, our approach calculates the consensus on a single camera. Furthermore, the responsibility for this calculation is migrated to the camera actually detecting the object with a better subjective view than its neighbors. This saves resources and reduces the communication overhead within the network.

    [BibTeX] [Abstract]

    In this work Sparse Approximation methods for frequency estimation of complex exponentials in white Gaussian noise are evaluated and compared against classical frequency estimation approaches. We use a non-equidistant sampling scheme which allows reconstructing frequencies far beyond the Nyquist rate. The evaluation is done for signals composed of one single complex exponential or the sum of two complex exponentials. We show that for the latter case the SA methods outperform the classical approaches. Especially when only a small number of signal samples are available the performance gain becomes significant.

    Modern compute systems continue to evolve towards increasingly complex, heterogeneous and distributed architectures. At the same time, functionality and performance are no longer the only aspects when developing applications for such systems, and additional concerns such as flexibility, power efficiency, resource usage, reliability and cost are becoming increasingly important. This does not only raise the question of how to efficiently develop applications for such systems, but also how to cope with dynamic changes in the application behaviour or the system environment. The EPiCS Project aims to address these aspects through exploring self-awareness and self-expression. Self-awareness allows systems and applications to gather and maintain information about their current state and environment, and reason about their behaviour. Self-expression enables systems to adapt their behaviour autonomously to changing conditions. Innovations in EPiCS are based on systematic integration of research in concepts and foundations, customisable hardware/software platforms and operating systems, and self-aware networking and middleware infrastructure. The developed technologies are validated in three application domains: computational finance, distributed smart cameras and interactive mobile media systems.

    Dynamic Power Management (DPM) refers to a set of strategies that achieves efficient power consumption by selectively turning off (or reducing the performance of)a system components when they are idle or are serving light workloads. This paper presents a Reinforcement Learning (RL)based DPM technique for a portable, multi-camera traffic monitoring system. We target the computing hardware of the sensing platform which is the major contributor to the entire power consumption. The RL technique used for the DPM of the sensing platform uses a model-free learning algorithm that does not require a priori model of the system. In addition, a robust workload estimator based on an online, Multi-Layer Artificial Neural Network (ML-ANN) is incorporated to the learning algorithm to provide partial information about the workload and to take better decisions according to the changing workload. Based on the estimated workload and a selected power-latency tradeoff parameter, the algorithm learns to use optimal time-out values in sleep and idle modes of the computing hardware. Our results show that the learning algorithm learns an optimal DPM policy for the non-stationary workload, while significantly reducing the power consumption and keeping the system response to a desired level.

    Smart camera networks usually have limited re- sources. This includes not only processing power and memory but in many applications also the amount of available energy. To find a trade-off between available resources and the current requirements of the application, the configuration of the network is very important. Due to rapid changes in the visual sensor network’s environment, reconfiguration must be dynamic and performed online. The reconfiguration must also be able to deal with heterogeneous tasks assigned within the network where the tasks require varying levels of dynamic actions by the cameras. In this paper we present a fully distributed algorithm for a combined spatial coverage and object handover problem. In our approach we focus on (i) assigning heterogeneous tasks to cameras in order to cover a certain area of interest (ii) hand over moving objects between cameras to allow seamless tracking and (iii) perform (i) and (ii) in a combined fashion to maximize the overall quality of surveillance while minimizing the resources required during operation.

    The temporal correlation of interference is a key performance factor of several technologies and protocols for wireless communications. A comprehensive understanding of interference correlation is especially important in the design of diversity schemes, whose performance can severely degrade in case of highly-correlated interference. Taking into account three sources of correlation — node locations, channel, and traffic — and using common modeling assumptions — random homogeneous node positions, Rayleigh block fading, and slotted ALOHA traffic — we derive closed-form expressions and calculation rules for the correlation coefficient of the overall interference power received at a certain point in space. Plots give an intuitive understanding as to how model parameters influence the interference correlation.

    In this paper we present increased adaptivity and robustness in distributed object tracking by multi-camera networks using a socio-economic mechanism for learning the vision graph. To build-up the vision graph within a distributed smart-camera network, we use an ant-colony inspired mechanism, which exchanges responsibility for tracking objects using Vickrey auctions. Employing the learnt vision graph allows the system to optimise its communication. Since distributed smart camera networks are prone to uncertainties in individual cameras, such as failures or changes in extrinsic parameters, the vision graph should be sufficiently robust to enable seamless tracking and optimised communication. To better reflect real smart-camera platforms and networks, we consider that communication and handover are not instantaneous, and that cameras may be added, removed or their properties changed during runtime. Using our dynamic socio-economic approach, the network is able to continue tracking objects well, despite these uncertainties, and in some cases with improved performance. This demonstrates the adaptivity and robustness of our approach.

Using our dynamic socio-economic approach, the network is able to continue tracking objects well, despite these uncertainties, and in some cases with improved performance. This demonstrates the adaptivity and robustness of our approach.},

    Systemic properties of living cells are the result of molecular dynamics governed by so-called genetic regulatory networks (GRN). These networks capture all possible features of cells and are responsible for the immense levels of adaptation characteristic to living systems. At any point in time only small subsets of these networks are active. Any active subset of the GRN leads to the expression of particular sets of molecules (expression modes). The subsets of active networks change over time, leading to the observed complex dynamics of expression patterns. Understanding of these dynamics becomes increasingly important in systems biology and medicine. While the importance of transcription rates and catalytic interactions has been widely recognized in modeling genetic regulatory systems, the understanding of the role of degradation of biochemical agents (mRNA, protein) in regulatory dynamics remains limited. Recent experimental data suggests that there exists a functional relation between mRNA and protein decay rates and expression modes. In this paper we propose a model for the dynamics of successions of sequences of active subnetworks of the GRN. The model is able to reproduce key characteristics of molecular dynamics, including homeostasis, multi-stability, periodic dynamics, alternating activity, differentiability, and self-organized critical dynamics. Moreover the model allows to naturally understand the mechanism behind the relation between decay rates and expression modes. The model explains recent experimental observations that decay-rates (or turnovers) vary between differentiated tissue-classes at a general systemic level and highlights the role of intracellular decay rate control mechanisms in cell differentiation.

    Unmanned aerial vehicles (UAVs) are an emerging research area. We equip them with high resolution cameras and build a wireless network for wide area surveillance. The sensed data is processed on-board and transmitted over the wireless network to generate an orthographic mosaic. In this work we present an image transmission scheduling and incremental mosaicking approach. Our experiments with up to four UAVs demonstrate very short delays for the final mosaic, due to the prioritization of image resolution levels and the incremental mosaicking starting from low resolution unconnected images.

    We evaluate the packet delivery performance of low-complex cooperative relaying in car-to-car communications by real-world measurements. The ratio and temporal correlation of packet delivery are evaluated for suburban and highway environments using three cars equipped with programmable radios and serving as sender, relay, and destination. We compare the relaying performance to that of pure time diversity and show how temporal autocorrelation of packet delivery is a key factor in whether or not relaying exhibits benefits. Results are relevant in the design of relay selection protocols, as they give guidelines for the affordable selection delay.

    Cooperative relaying is a communication technique that has been shown to improve link reliability between communicating entities. Most results in this area are obtained either analytically or via simulations. Rather few real-world experiments are conducted to backup theoretical results. This paper intends to go a step in this direction of applied research. We study the performance of cooperative relaying for industrial applications based on real-world measurements. These link-level measurements are conducted employing low-cost, offthe- shelf IEEE 802.15.4 devices in a factory characterized by a harsh and cluttered environment. Using the measured data, we emulate a simple cooperative relaying protocol to investigate the performance in terms of outage and packet delivery.

    The implementation of an auto focus algorithm is an important and crucial feature for infrared microscopy. To detect focus images, the entire infrared camera has to be moved due to the fact that a microscope camera system employs a fixed lens. In our work, we present the concept of a real time auto focus algorithm especially for infrared imaging of power semiconductor chips. Three auto focus functions are implemented and compared: the gradient operator, the Sobel edge detection and the 2D Fast Fourier Transformation (FFT). The main goal is to identify the function which can robustly detect the focus image on varying temperatures and at changing intensities.

    Lens distortion as a result of the shape and construction of a photographic lens is a common problem in image acquisition. Thermal cameras are no exception to this artifact. So far many methods have been developed to formulate the distortion model and almost all of them exploit the patterns in visible range to calibrate the lenses in RGB cameras. A checkerboard is among the most common and well-defined patterns for RGB camera calibration. Unfortunately, most of those patterns will not be easily visible in images taken by a thermal camera. Furthermore, since the thermal cameras measure the infrared radiation (heat), the conductivity of the heat to the bordering objects in the pattern might mitigate sharp edges, which will make detection of relevant features within the pattern harder and less precise. In this paper we propose an algorithm to construct a calibration pattern visible for the thermal infrared cameras. We show how to extract robust features out of the sensed checkerboard pattern which is used afterward for lens distortion correction. Further, we evaluate our method and compare it to results obtained from well established algorithms for visible-light lens calibration. We also demonstrate how distortion correction improves the image registration between thermal and RGB aerial images taken by small-scale unmanned aerial vehicles (UAVs).

Further, we evaluate our method and compare it to results obtained from well established algorithms for visible-light lens calibration. We also demonstrate how distortion correction improves the image registration between thermal and RGB aerial images taken by small-scale unmanned aerial vehicles (UAVs).},

    This article investigates probabilistic information dissemination in stochastic networks. The following problem is studied: A source node intends to deliver a message to all other network nodes using probabilistic flooding, i.e., each node forwards a received message to all its neighbors with a common network-wide forwarding probability ω. Question is: what is the minimum ω-value each node should use, such that the flooded message is obtained by all nodes with high probability? We first present a generic approach to derive the global outreach probability in arbitrary networks and then focus on Erdős Rényi graphs (ERGs) and random geometric graphs (RGGs). For ERGs we derive an exact expression. For RGGs we derive an asymptotic expression that represents an approximation for networks with high node density. Both reliable and unreliable links are studied.

    A visual sensor network (VSN) consists of a large amount of camera nodes which are able to process the captured image data locally and to extract the relevant information. The tight resource limitations in these networks of embedded sensors and processors represent a major challenge for the application development. In this paper, we focus on finding optimal VSN configurations which are basically given by: 1) the selection of cameras to sufficiently monitor the area of interest; 2) the setting of the cameras’ frame rate and resolution to fulfill the quality of service requirements; and 3) the assignment of processing tasks to cameras to achieve all required monitoring activities. We formally specify this configuration problem and describe an efficient approximation method based on an evolutionary algorithm. We analyze our approximation method on three different scenarios and compare the predicted results with measurements on real implementations on a VSN platform. We finally combine our approximation method with an expectation-maximization algorithm for optimizing the coverage and resource allocation in VSN with pan-tilt-zoom camera nodes.

    Cooperative diversity is a communication technique where a relay node provides signal diversity to the destination by retransmitting the signal received from the source. To find an optimal relay and maximize the resulting performance, a relay selection procedure is used with channel state information as a selection metric. In this paper, we model cooperative diversity with relay selection as a Markov chain, and study the impact of selection timing on throughput and energy efficiency in Rayleigh fading channels. Based on obtained results, we determine optimal relay selection schemes for various network scenarios.

    [BibTeX] [Abstract]

    In this work we examine the impact of dynamical environments on evolutionary algorithms and ant colony optimization. In particular we evaluate these algorithms for a shortest path problem in a continuously changing network. The problem of establishing the shortest or cheapest path in a randomly changing network acts as a representative for the class of situations to be solved. Also nodes are added and removed to this network being reminiscent of today’s wireless networks consisting of a variety of mobile devices having changing signal quality between the participants and peers entering and leaving the networks. Within this problem definition lies the possibility of radical changes since former best paths may not exist any longer and may have collapsed after a series of such changes. Resilience to and recovering from such incidents correspond to the robustness quality whereas finding the best solution in the least number of steps indicate good performance values. We first simulate a radical Darwinistic approach; the genes of individuals of a population are recombined and mutated randomly, evaluated by a fitness function and, dependant on the fitness value, selected for the next generation in order to gradually create a better performing population over several generations. The results are compared to a set of different Ant Colony Systems best suited for this class of problems. Choosing different evaporation rates, greediness and visibility values constitute to a variety of ACS instances yielding candidates for the optimal problem solution with respect to the quality criteria objective. The goal of this work is to obtain a better understanding of these techniques when designing and building complex systems. The results derived from this work may give new insights when creating self organizational systems based on artificial neuron networks and evolutionary algorithms in mind.

    The LIN protocol was developed by a consortium of seven automotive partners (Audi, BMW, DaimlerChrysler, Volvo, Volkswagen, Motorola and VCT) as a complementary system to the widely used CAN bus. In 2003, many updates to reflect the latest off-the-shelf microcontrollers as well as inputs from the SAE Task Force resulted in the definition of LIN 2.0. In fact, LIN 2.0 was a complete rework of the existing LIN 1.3 standard, but backward compatible. The most recent version of the specification is LIN 2.1.

    [BibTeX] [Abstract]

    This paper presents an adaptive inventory control system based on neuro‐fuzzy logic. In particular we describe a control system using adaptive neuro‐fuzzy interference (ANFIS) for calculating the optimal value of the storage level of goods. An implementation in MATLAB had been used to test and verify the proposed idea for the economic order quantity as a simple inventory control system. Our results shows that the presented approach is able to determine the optimal stock level and cost without knowing the exact mathematical model of the examined system.

    [BibTeX] [Abstract]

    The TTP/A protocol is the low-cost field-bus protocol that is harmonized with the fault-tolerant system bus TTP/C of the time-triggered architecture (TTA). It is intended for the connection of smart sensors and actuators in embedded real-time systems in different application domains, e.g., industrial, automotive, etc. It is the objective of TTP/A to provide all services needed by a smart sensor, including timely communication, remote on-line diagnostics, and plug-and-play capability. While LIN is powered by industrial sponsors, TTP/A is an academic development started by the Technical University of Vienna, Austria and then broadened to include the Technical University of Munich, Germany and the University of Stuttgart, Germany. The first version of TTP/A was published at the SAE World Congress in 1995. Since then, TTP/A has been extended by a plug-and-participate function and a unique interface scheme in form of an Interface File System (IFS).

    Many of the current bio-inspired delivery networks set their focus on search, e.g., by using artificial ants. If the network size and, therefore, the search space gets too large, the users experience high delays until the requested content can be consumed. In this paper we propose replication strategies to reduce this delay. Typical mechanisms, applied in unstructured P2P networks, such as replication at the target (owner replication) and replication on the travel path of content (path replication) are either inefficient or the user experience suffers because of the long distance between content and requester. Based on an previously introduced self-organizing hormone-based delivery algorithm, we compare seven existing and proposed replication mechanisms.We show by simulation that the exploitation of local knowledge about the desire for the requested content performs best in scale-free and random networks. These results are expected to provide a guide towards designing future self-organizing bio-inspired networks.

    Unmanned aerial vehicles (UAVs) are an emerging research area and we equip these with high resolution cameras and build a wireless network for wide area surveillance. The sensed telemetry data and images are processed on-board in a distributed manner to generate an orthographic mosaick and augment with sensed data. In this work we present a prioritized data transmission scheme for a wireless network of mobile aerial camera nodes for wide area surveillance. The goal of this protocol is to transfer the telemetry data, mosaicking data and images efficiently over the limited wireless network such that an overview image can be generated incrementally. Our experiments with up to four UAVs demonstrate very short delays for the final mosaick, due to the prioritization by the network protocol. Low resolution image data and meta data for mosaicking is prioritized over the full sized image data.

    [BibTeX] [Abstract]

    The recently presented UW-OFDM (Unique Word – orthogonal frequency division multiplexing) signaling scheme [1] uses certain subcarriers in frequency domain for redundant symbols instead of data, in order to generate a zero word in the DFT (discrete Fourier transform) interval in time domain. These redundant symbols depend on the data loaded on the other carriers and thus introduce correlation. The resulting linear system model enables sophisticated detectors for data recovery. As the best known maximum likelihood detector for this case, we applied the Sphere Decoding (SD) algorithm to a single antenna UW-OFDM system and evaluated its bit error performance in AWGN (additive white Gaussian noise) and frequency selective environments. Compared to linear receivers, the SD is able to take the correlations on the redundant subcarriers optimally into account and shows an enormous gain. A reduction of the redundant energy by increasing the number of redundant subcarriers improved the bit error performance of UW-OFDM systems with linear data estimators [2] at the price of a lower bandwidth efficiency. In contrast it is found, that a receiver based on Sphere Decoding is able to optimally exploit the excess redundant energy. The SD based system therefore shows its best performance at maximum bandwidth efficiency.

    In this approach we estimate the depth structure of sceneries in aerial images captured by small-scale UAVs to improve the mosaicking of an orthographic overview image. Initial image transfor- mations derived from inaccurate position and orien- tation data of UAVs are enhanced by the camera pose obtained using Structure from Motion. Correspond- ing points are then selected on a common ground plane to find accurate image transformations. The resulting mosaick preserves distances and minimizes distortions. A rough placement is immediately pre- sented and optimized incrementally if more images are considered.

    We investigate the impact of time diversity and space-time diversity schemes on the traffic capacity of large-scale wireless networks with low-cost radios. Especially, we analyze the tradeoff between relaying gain and increased interference due to additional traffic. The results of a simulation-based study imply that cooperative relaying with selection combining shows benefits for low interference scenarios. For high traffic, however, higher-order modulation schemes outperform the investigated cooperative relaying scenario due to lower interference.

    The full coherent processing of non-equidistant sampled data has been the topic of many research activites. In this paper we propose a processing chain based on such an algorithm, the Fit-to-Sine function, which is able to handle multitarget and target/clutter radar signals. Starting from he computation of a least squares cost funtkon in dependency of frequency, followed by a feature extraction method and the suppression of unwanted sidelobes, we conduct a simple noise/target distinction by utilizing basic fuzzy logic characteristics and operations. Finally we exemplify our processing chain and the achievable results on a real radar scenario with a target moving in strong clutter.

    Pervasive smart cameras (PSC) are an emerging technology with the goal of providing user-centric and ubiquitous visual sensor networks. System autonomy and resource-awareness are challenging requirements making local image processing for event-based communication a necessary design constraint. In this paper we present the distributed event space (DES)–-a middleware service for the resource-aware management of distributed event data. The DES architecture is based on a decentralized tuple space which describes local events by tuples consisting of position and time of the events as well as a set of features describing the detected objects. The DES supports prompt distribution of detected local events and application-specific functions for sophisticated event filtering. We present a distributed tracking application to demonstrate its applicability.

    This paper reports on an experimental study about some benefits of cooperative relays in mobile wireless communications. A basic technique for cooperative relaying is implemented in the programmable hardware platform WARP. Using this implementation, measurements are made for mobile car-to-car communications in a suburban environment. Each of three cars is equipped with a transceiver and serves as sender, relay, or destination, respectively. Results demonstrate that cooperative relaying communications exhibit performance gains over conventional direct communications and time-diversity communications in terms of packet delivery rate, bit error rate, and packet error rate. We account for energy fairness by using half transmission power for cooperative relaying and time diversity communications.

    Decentralized synchronization requires cooperation among network participants so that all nodes agree on a common reference timing. What happens if one node does not follow local synchronization rules and randomly transmits? This paper studies the resilience of two classes of decentralized slot synchronization against random disturbances, and quantifies the impact of the random behavior. It is shown that the coupling strength is a key factor for resilience, and that the synchronization approach based on the theory of coupled oscillators generally behaves better and is more robust than the approach that updates clocks based on the average neighboring timings.

    Distributed smart cameras (DSC) are an emerging technology for a broad range of important applications including smart rooms, surveillance, entertainment, tracking, and motion analysis. By having access to many views and through cooperation among the individual cameras, these DSCs have the potential to realize many more complex and challenging applications than singlecamera systems. This article focuses on the system-level software required for efficient streaming applications on single smart cameras as well as on networks of DSCs. Embedded platforms with limited resources do not provide middleware services well known on general-purpose platforms. Our software framework supports transparent intra- and interprocessor communication while keeping the memory and computation overhead very low. The software framework is based on a publisher–subscriber architecture and provides mechanisms for dynamically loading and unloading software components as well as for graceful degradation in case of software- and hardware-related faults. The software framework has been completely implemented and tested on our embedded smart cameras consisting of an ARM-based network processor and several digital signal processors. Two case studies demonstrate the feasibility of our approach.

    Self-organizing systems could serve as a solution for many technical problems where properties like robustness, scalability, and adaptability are required. However, despite all these advantages and due to the decentralized control there is no straight-forward way to design such a system. In this paper we describe a novel design approach using genetic algorithms and artificial neural networks to automatize the part of the design process that requires most of the time. A simulated robot soccer game was implemented to test and evaluate the proposed method. A new approach in evolving competitive behavior is also introduced using Swiss System instead of the full tournament to cut down the number of necessary simulations.

A simulated robot soccer game was implemented to test and evaluate the proposed method. A new approach in evolving competitive behavior is also introduced using Swiss System instead of the full tournament to cut down the number of necessary simulations.},

    [BibTeX] [Abstract] [Download PDF]

    This paper describes the design and implementation of a distributed self-stabilizing clock synchronization algorithm based on the biological example of Asian Fireflies. Huge swarms of these fireflies use the principle of pulse coupled oscillators in order to synchronously emit light flashes to attract mating partners. When applying this algorithm to real sensor networks, typically, nodes cannot receive messages while transmitting, which prevents the networked nodes from reaching synchronization. In order to counteract this deafness problem, we adopt a variant of the Reachback Firefly Algorithm to distribute the timing of light flashes in a given time window without affecting the quality of the synchronization. A case study implemented on 802.15.4 Zigbee nodes presents the application of this approach for a time-triggered communication scheduling and coordinated duty cycling in order to enhance the battery lifetime of the nodes.

    [BibTeX] [Abstract]

    In many simulations a receiver is considered not to be interfered by other senders if they are placed all further away than a given threshold distance dt. This corresponds to a simple circle model, i.e. a circle around a receiver of radius dt is void of other senders. This common simplification disregards the fact that the combined interference power of several senders outside the threshold distance will still hinder reception. In this paper we present the theory of a circle model generalized to w circles that is able to consider further away interferers and thus provide more accurate results. Comparisons of our theoretic findings to simulative results confirm the soundness of the new model.

    In this paper we analyze the robustness of sorting and tournament algorithms against faulty comparisons. Sorting algorithms are affected by faulty comparisons differently depending how comparison errors can affect the overall result. In general, there exists a tradeoff between number of comparisons and accuracy of the result, but some algorithms like Merge Sort are Pareto-dominant over others. For applications, where the accuracy of the top rankings is of higher importance than the lower rankings, tournament algorithms such as the Swiss System are an option. Additionally, we propose a new tournament algorithm named Iterated Knockout System which is less exact but more efficient than the Swiss System.

    We measure radio channel characteristics of a car-to-car communication scenario in an urban environment. The measurements are performed with two WARP boards, where one of the boards acts as the sending node and the other as the receiving node. Each of the boards is attached to a car and transmits or receives data while the cars are in motion. The measurements are analyzed and a model for the expected reception power is derived. Furthermore, we model shadow fading and fast fading and also give information about bit error ratios.

    [BibTeX] [Abstract] [Download PDF]

    Cooperative relaying is a communication technique in wireless networks where neighboring nodes assist communication pairs to mitigate the negative effects of multi-path fading. The resulting performance strongly depends on the selected relays. Although a cooperative relay provides benefits to a given source-destination pair, overall network performance might be degraded due to the increased level of interference. So far almost all relay selection mechanisms consider mainly channel conditions to the potential relays. In this paper we propose a contention-based relay selection mechanism that can take into account also spatial efficiency of potential relays. For that the degree as well as relative position of the nodes are used for selection. With the proposed method a high successful relay selection probability can be achieved, while significantly reducing the amount of additional spatial resources blocked by the cooperative relay.

    Cooperative relaying has drawn great interest to mitigate the negative effects of small-scale fading in distributed wireless networks. This paper analyzes radio resource allocation in cooperative relaying with proactive relay selection. Due to the introduction of the relay into the communication link an over-expenditure of resources can take place similar to the classical exposed terminal problem. In this work we derive the overall network throughput in two simple scenarios and determine the regions of packet-error-rates where cooperative relaying yields a throughput gain.

    Consider n nodes competing for access on a channel using slotted ALOHA. Our aim is to maximize the probability Phi that the first message within s slots does not collide. We derive an expression for the transmit probabilities in each slot, maximizing Phi. As opposed to previous work, the expression is non-recursive, thus easier to calculate and more convenient for practical implementations. Furthermore, we address the problem that, in practical applications, the number of competing nodes n is likely to be unknown and has to be estimated by each node. We study the sensitivity of channel access scheme with respect to deviations from the actual n via simulations. It is shown that overestimation of n is a better strategy than underestimation.

    The behavior of a self-organizing system (SOS) is typically defined by the local interaction rules of the components. While this emergent behavior typically is very flexible, i.e., working at different scales being robust against disturbances and failures, there exists no straight-forward way for the design of these rules so that the overall system shows the desired properties. The try and error methods, even when being improved using notions such as the “friction” between two components often suffer from counter-intuitive interrelationships between local rules and emergent behavior. Imitation approaches, such as the bio-inspired methods or the programming of the local behavior by analyzing an example using perfect knowledge are limited to the cases where an appropriate example model is available. Therefore, we investigate on novel generic approaches for designing self-organizing systems. E.g., promising methods could be genetic algorithms or particle swarm optimization methods. A possible approach to model the local interaction in a way that can be evolved is given by neural networks. In the long term, we aim at a generic optimization tool for designing and exploring rulesets for SOS designs.

    This paper studies probabilistic information dissemination in random networks. Consider the following scenario: A node intends to deliver a message to all other nodes in the network (“flooding”). It first transmits the message to all its neighboring nodes. Each node forwards a received message with some network-wide probability pf . A natural question arises: which forwarding probability pf should each node use such that a flooded message is obtained by all nodes with high probability? In other words, what is the minimum pf to achieve a high global outreach probability? We first present a generic approach to estimate the probability for achieving global outreach. This approach is then employed in Erd?os R´enyi random graphs, where we derive an upper and a lower bound for the global outreach probability for given random network and flooding parameters. The analysis is complemented with simulation results showing the tightness of both bounds. As a final result, we take a system design perspective to show a number of parameter vectors leading to global outreach.
