Interference by drones to ground users

Aerial drones connected to cellular networks can affect the throughput of common cell phone users. System-level simulation results were presented at an ACM MobiSys workshop earlier this week. Today’s commercial drones rely on Wi-Fi and proprietary technologies for wireless connectivity. Alternatively, drones could connect to cellular networks, like 5G, which […]

Interference prediction in wireless networks

If two musicians were to play at the same concert venue simultaneously, it would not only sound terrible, but it would also be impossible to understand the song lyrics. The same is true whenever huge volumes of data is exchanged between sensors nodes. Mahin Atiq is working to predict the […]

Scholarship for Daniel Neuhold

Daniel Neuhold, researcher in the team of Christian Bettstetter, received a “scholarship of excellence” from the Federation of Austrian Industries (Carinthia) and the Economic Chamber for a six-month research stay abroad.

Bit error rate in Poisson networks

In mobile communication systems, like UMTS or WLAN, the transmissions of different mobile devices interfere with each other. For example, when a mobile device transmits signals to its base station, other mobile devices transmitting on the same frequency band cause interference at that base station, which in turn may result […]

UWB sensor networks in airplanes

Modern airplanes are equipped with hundreds of embedded sensors and actuators necessary for structural health monitoring, aircraft control, and passenger and crew assistance. These devices are typically interconnected by wires. Using wireless connections instead of wires improves flexibility of installations and reduces the airplane’s weight. Researchers from Airbus Group Innovations […]

Interference functionals in wireless networks

Wireless networks are often modeled using tools from stochastic geometry. A team of researchers from Klagenfurt, Athens, and Notre Dame now contributed to these tools by solving general sum-product functionals for Poisson point processes. Link outage probabilities are derived for networks with interference and Nakagami fading.
