A Novel Resource Sharing Mechanism for Device-to-Device Communications Underlaying LTE-A Uplink Cellular Networks

Underlaying Device-to-device (D2D) communication is intimated as an encouraging technology for the next generation cellular network, where nearby devices can directly communicate to one another abstaining the evolved nodeB (eNB). In this paper, we propose a resource sharing mechanism which employs for multiple D2D communications by sharing a single cellular link simultaneously. In order to minimize the interference caused by multiple D2D pairs while sharing single cellular link at a time, we propose a meta-heuristic algorithm based on the comprehensive interference minimization with reference to an uplink cellular network. The simulation results demonstrate that the proposed algorithm attains efficient performance compared with basic schemes.
