Impact of Full Duplex Scheduling on End End-to-End End Throughput in Multi Multi-Hop 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 network network remains unclear. As for multi multi-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-hop multi 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 problem. problem. The results in this paper offer some new understandings on the potential benefits of FD for end-to-end end end session throughput in a multi-hop hop wireless network.
