Abstract: “As the rapid developing of mobile communication, the Long Term Evolution Advanced (LTE-Advanced) with high speed transmission is becoming the mainstream of mobile communication system, and the technique of relay plays an important role among all. Relay Node (RN) has advantages including low power, lower cost and system deployment easily which can enhance system capacity, coverage area, and reduce network deployment cost. How to increase the range of coverage effectively but also give consideration to reduce the cost is a great challenge. This paper adopts Particle Swarm Optimization with Time Varying Acceleration Coefficients (PSO-TVAC) which has distributed memory and contiguous range searching function, that applies to Evolved NodeB (eNB) and Relay Node to deploy network in particular area for lower cost of network deployment and ensure the area coverage. The simulation results show that the proposed PSO-TVAC compares with Setcover Algorithm and PSO in deployment with eNBs, eNBs and”
