Resource Allocation for D2D Communications in Mobile Networks

To improve the network capacity without additional costs, Device-to-device (D2D) communication technology establishes direct links between users while reusing the same spectrum of traditional communication between base station and cellular users. In this paper, an efficient resource allocation scheme is proposed for D2D communications to overcome the interference caused by the presence of multiple connections sharing the same spectrum. The capacity of the network is optimized by maximizing the number of all served users while considering a tradeoff between quality of service and power consumption. Simulations of the proposed scheme in different radio conditions showed that the number of D2D communications increases significantly which indicates the efficiency of the novel resource allocation scheme.
