Impact of Full Duplex Scheduling on End End-to-End End Throughput in Multi-Hop Multi Wireless Networks
Abstract: There have been some rapid advances on the design of full duplex (FD) transceivers in recent years. Although the benefits of FD have been studied for single-hop hop wireless communications, its potential on throughput performance in a multi-hop hop wireless networ network remains unclear. As for multi-hop hop networks, a fundamental problem is to compute the achievable end end-to-end end throughput for one or multiple communication sessions. The goal of this paper is to offer some fundamental understanding on end end-to-end throughput performance rformance limits of FD in a multi-hop hop wireless network. We show that through a rigorous mathematical formulation, we can cast the multi multi-hop hop throughput performance problem into a formal optimization problem. Through numerical results, we show that in many cases, the end-to-end end session throughput in a FD network can exceed 2x of that in a half duplex (HD) network. Our finding can be explained by the much larger design space for scheduling that is offered by removing HD constraints in throughput maximization p problem. roblem. The results in this paper offer some new understandings on the potential benefits of FD for end end-to-end end session throughput in a multi-hop hop wireless network.
