Abstract: Address to interference problems faced by D2D (device-to-device) communication users in the process of multiplexing traditional cellular communication channel resources, a resource allocation algorithm based on particle swarm optimization (PSO) algorithm for D2D communication power matching joint interference control is proposed in this paper, which maximizes the throughput of the whole system while controlling interference. Firstly, security communication are divided into different ranges according to threshold values of user-powers, and only the users in the security communication range have opportunity to join in subsequent power distribution, thus effectively reducing system interference. Secondly, a power matching method based on PSO is adopted to take D2D senders as particle swarm. It maximizes the throughput of the whole system by searching for the optimal power through iteration. Simulation results show that the proposed algorithm can significantly improve the overall throughput of the system and minimize the interference, so as to achieve the optimal communication quality of the whole system.
