UAV Relay

UAV relay technology focuses on using unmanned aerial vehicles to extend communication range and improve connectivity, particularly in challenging environments or for mobile targets. Current research emphasizes optimizing UAV placement and trajectories to minimize outage probability and maximize throughput, often employing reinforcement learning, semi-Markov decision processes, or heuristic algorithms to address complex optimization problems involving channel conditions, power constraints, and multi-hop communication. This field is significant for enhancing the performance of various applications, including environmental monitoring, surveillance, and distributed learning in areas with limited infrastructure or connectivity challenges.
