Distributed resource allocation in full-duplex relaying networks with wireless virtualization

Abstract

Wireless network virtualization has attracted a lot of interests recently. Furthermore, recent advances of self-interference cancellation techniques enable full-duplex relaying (FDR) systems, which transmit and receive simultaneously in the same frequency band with high spectrum efficiency. In this paper, we propose a resource allocation scheme for virtualized FDR networks. The resource allocation problem is formulated as a mixed combinatorial and non-convex optimization problem, which involves high computational complexity. Therefore, we transfer the original problem to a convex optimization problem, which can be solved efficiently. In addition, with recent advances in alternating direction method of multipliers (ADMM), we develop an efficient ADMM-based distributed resource allocation algorithm. Extensive simulations are presented to verify the effectiveness of the proposed scheme.
