The problem of finding a consensus in a group of people occurs in many social contexts. In a similar way, distributed algorithms for consensus play an important role in networked computing and communication systems if centralized decision making is difficult or impossible. Each entity in such a system processes only […]
How can multiple mobile robots may be utilized to explore unknown buildings? Torsten Andre and a team of students developed and implemented software packages for the robot operating system for this purpose.
The European project “Engineering Proprioception in Computing Systems (EPiCS)” has been successfully completed with the final review meeting in Brussels. leading experts have investigated the design of novel computing systems by means of self-awareness and self-expression — concepts originally developed in psychology.
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.
Two projects completed during summer internships at our institute received various awards: The students Günther Cwioro and Peter Kohout developed methods for communication between mobile robots and the exchange of maps. They won the largest nationwide school competition Jugend Innovativ in the category Electrical Engineering. The project “Talk Talk” on […]
The key idea behind cooperation in wireless networks is that devices help each other to communicate messages properly over the air. When a transmitter sends messages to a receiver, adjacent devices can overhear these messages. If the direct transmission to the receiver fails, one of those devices can retransmit (“relay”) […]
