Performance Of Particle Swarm Optimization On Subcarrier Allocation For Device-To-Device Multicasting In Wireless Communication Systems

In this study, we propose Particle Swarm Optimization (PSO) algorithms for Device-to-Device multicasting (D2DM) subcarrier allocation. The multimedia services provided by 5G communication are required to meet their own Quality of Service (QoS). In addition, it is well known that the Orthogonal Frequency Division Multiple Access (OFDMA) can improve the transmission efficiency. Therefore, this research aims to enhance the effectiveness ofD2D multicast resource allocation in OFDMA system by using PSO while maintaining the QoS. Both the QoS threshold and transmission threshold are employed to be the basis for allocation of subcarriers. Simulation results show that the proposed Linear PSO (LPSO) obtains the best performance on subcarrier allocation for the CeUEs with QoS guarantee, and thus achieved higher D2DMs throughput performance than original PSO (OPSO) and traditional heuristic methods.
