The University of Klagenfurt launches a two-year master program in Information and Communications Engineering (ICE). The program is taught entirely in English and is recommended for students with an undergraduate degree in electrical or computer engineering.
New packages for the Robot Operating System (ROS) are available for autonomous exploration of unknown environments using collaborating mobile robots equipped with cameras. The software offers wireless ad hoc communications between robots, merging of maps from different robots, and coordinated selection of exploration frontiers. A prototype with four robots was built that demonstrates its functionality in an indoor environment.
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.
A new article published in the IEEE Communications Magazine discusses some aspects of wireless communications for different applications involving small drones.
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 precision in the low microsecond range when being implemented in the physical layer.
We analyze a wireless communication system with multiple relays operating in an interference-limited setting. Analytical results derived for different interferer placement show that the temporal and spatial characteristics of the interference have significant impact on the system performance.
A protocol for the selection of relay devices operating in the data link layer of wireless networks was proposed, specified, and evaluated. It is now being tested in a vehicular environment.
Different communication protocols for relay selection in wireless networks have been modeled using Markov chains in order to analyze and compare their performance.
