A Survey of Air-to-Ground Propagation Channel Modeling for Unmanned Aerial Vehicles

In recent years, there has been a dramatic increase in the use of unmanned aerial vehicles (UAVs), particularly for small UAVs, due to their affordable prices, ease of availability, and ease of operability. Existing and future applications of UAVs include remote surveillance and monitoring, relief operations, package delivery, and communication backhaul infrastructure. Additionally, UAVs are envisioned as an important component of 5G wireless technology and beyond. The unique application scenarios for UAVs necessitate accurate air-to-ground (AG) propagation channel models for designing and evaluating UAV communication links for control/non-payload as well as payload data transmissions. These AG propagation models have not been investigated in detail when compared to terrestrial propagation models. In this paper, a comprehensive survey is provided on available AG channel measurement campaigns, large and small scale fading channel models, their limitations, and future research directions for UAV communication scenarios

Pursuit-evasion Game

In Pursuit-Evasion Games (PEGs) multiple robots (the pursuers) collectively determine the location of one or more evaders, and try to corral them. The game terminates when every evader has been corralled by one or more robots. PEGs have motivated interesting research directions in multi-robot coordination. Pursuers may not have line-of-sight visibility to evaders, and a sensor network can help detect and track evaders.PEG is an application case study of Tenet, a software architecture for Wireless Sensor Network. Tenet architecture provides a wireless subtract for pursuer to communicate and collect sensor data. Tenet simplifies the development of the wireless sensor applications, since it is not necessary to worry about reliability, mobility, routing tree and other issues
