Joint Optimization Method of Spectrum Resource for UAV Swarm Information Transmission

For the problems brought by malicious interference in unmanned aerial vehicle (UAV) swarm network, we establish a cluster-based UAV information transmission model. We mainly consider four aspects: cluster head selection, channel allocation, power allocation and position. In order to improve backhaul rate of swarm, propose joint optimization method spectrum resource with goal maximizing sum throughput UAV. decompose original mixed integer nonlinear programming (MINLP) problem into multiple sub-problems based on block coordinate descent (BCD) technique, then solve them convex successive approximation (SCA) technique. Simulation results show that proposed can obtain strategy transmission, reduce impact interference, effectively swarm.
