Full Duplex-Aware Backoff for Improving Channel Utilization in Full Duplex WLANs

Abstract

Even though full duplex (FD) communication, which allows simultaneous transmission and reception on the same frequency channel, is a promising technology to improve the throughput in wireless local area networks (WLANs), it suffers from under-utilization when communication patterns are asymmetric. In this paper, we propose a FD-aware backoff (FD-backoff) scheme to improve the utilization in FD-WLANs. Simulation results show FD-backoff achieves increase of throughput and fairness.
