Resource Allocation Based on SFLA Algorithm for D2D Multicast Communications

Multicast device-to-device (D2D) communication technology is considered as one of the new technologies in fifth generation (5G) networks that directly addresses need for content sharing among internet users. In fact, when direct available between devices, spectral efficiency improved by reusing licensed cellular spectrum. The current studies show D2D increases network capacity and reduces latency. order to achieve alternate capabilities, coordination required implement interference management. We subcarrier allocation uplink, addition power control takes place on underlay network. completed data rate single multicast significantly reduced limited nodes with lower channel quality. this paper, we used Shuffled Frog Leaping Algorithm (SFLA) resource (RA) communications. compared results SFLA algorithm Firefly (FA), Ant Colony Optimization (ACO) Particle Swarm (PSO); terms user throughput, Cellular User (CU) average signal noise ratio (SINR) target. simulation clearly outperforms other algorithms under high pressure infeasibility.
