Abstract

In a wireless communication environment, using UAV to relay network can improve user throughput. This is because the UAV’s mobility can maintain the connection of the user’s network and extend the communication range. This is useful when obstacles such as mountains or large buildings degrade the quality between the base station and the user or the distance between the base station and the user is long. Moreover, the cognitive radio technology allows more users to use the band of licensed users who are not using it to relay the network. In this paper, UAV relays using licensed user’s bandwidth through Cognitive Radio (CR) technology and simulated to improve the throughput of users located far from the base station. Simulation results show that user throughput is improved.
