Energy-efficient radio resource allocation for device-to-device underlay communication using combinatorial auction

Abstract

Device-to-Device (D2D) communication can greatly improve the resource utilization and system throughput as a result of resource reuse. Due to the severe interference caused by the D2D users to the cellular users, the resource allocation and power control should be arranged reasonably. In this paper, we put forward a novel joint resource and power allocation scheme in order to raise the system performance. We consider energy efficiency as our optimization goal. We propose a iterative combinatorial auction(ICA) game algorithm in which D2D UEs are viewed as bidders competing for channel resources occupied by the cellular users. Simulation results indicate that our algorithm performs well on system energy efficiency with lower consumption.
