Drones in cellular networks
A new project investigates the integration of unmanned aerial vehicles in 5G networks and proposes a hybrid connectivity solution with Wi-Fi. The work is led by Aymen Fakhreddine and advised by Christian Bettstetter. Funding comes from the Austrian Science Fund (FWF). Written by Christian Bettstetter and Aymen Fakhreddine Wireless connectivity is a fundamental component in drone systems with high demands for reliability, security, and performance. Some drone applications need to transmit huge amounts of data or require ultra-low latencies. The wireless technology used in most commercial drones is Wi-Fi, but it only partially meets the high requirements. Therefore, integrating drones into cellular networks is an exciting option, either as a replacement or supplement to Wi-Fi. A new three-year research project at the University of Klagenfurt addresses this issue. Funding was secured from the Austrian Science Fund (FWF) in the amount of about 288,000 € from the ESPRIT postdoctoral program. The work is embedded into many ongoing activities on multi-drone systems in Klagenfurt (uav.aau.at). “The integration of drones into cellular networks has not yet reached the …
Bit error rate in Poisson networks
Mathematical expressions for bit error rates in a wireless system are derived and provide insight into interference control.
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.
How interference dynamics influences wireless communications with relays
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.
