Abstract
Device-to-device (D2D) communication as an underlaying to cellular networks are prove to be efficient in improving the network performance and releasing the traffic load of base station (BS). However, the performance of both D2D user equipments (DUEs) and cellular user equipments (CUEs) can be affected by mutual interferences. Therefore, comprehensive coordination is indicated in the scheduling and allocation of channel resources and power to DUE communication. In our research, we analyze the multi-sharing resource allocation problem, which allows multiple DUEs to reuse the same radio resource that has been assigned to the particular CUE. We then concluded that the multi-sharing resource allocation problem is a NP-hard problem, and proposed a Stackelberg game for power control and channel allocation to improve the performance of D2D communications. We take both network throughput and quality of service (QoS) of CUE and DUE into consideration by implementing interference managements. We analyze the equilibrium of the game, and propose an algorithm for joint scheduling and resource allocation. Nevertheless, the simulation results show that the algorithm has better throughput and Jain's fairness index than the others.
