Path planning and communication optimizing in multi-UAVs cooperative communication relay

Communication network is the foundation for the multiple unmanned aerial vehicles (UAVs) to get more information and to exert the advantage of cooperative campaign when they are cooperating in communication relay tasks. This paper mainly focuses on the problem of search path planning and communication optimizing during the process of cooperative relay. The path planning is to find the location of moving crew on the ground and build up a communication network for UAVs to perform the relay task; the communication optimizing is to solve the problem of communication intermit and distortion during the process of relay, analyze the information routing of the network, choose communication delay as the performance index, and change the location of UAVs to improve network performance. Simulation results indicate that during the search task this approach can improve the performance of the network.
