Auction Based Energy-Efficient Resource Allocation and Power Control for Device-to-Device Underlay Communication

Abstract

Device-to-Device (D2D) communication underlaying cellular networks is expected to bring significant benefits for resource utilization and cellular coverage. However, the resource allocation and power control needs elaborate coordination, otherwise it may cause severe interference between D2D user equipment (DUE) and cellular user equipment (CUE). In this paper, we study the joint radio resource allocation and power control problem with energy efficiency as our optimization goal. To improve the system energy efficiency with low computational complexity, we propose an iterative combinatorial auction algorithm with flexible power control method, where the CUEs are considered as bidders, DUEs as goods and the cellular network plays a role as the auctioneer controlling the auction process. We also analyze the properties of the proposed algorithm and present numerical results to verify that our algorithm can significantly improve energy efficiency.
