End-to-End Fair Bandwidth Allocation in Multi-Hop Wireless Ad Hoc Networks
— The shared-medium multi-hop nature of wireless ad hoc networks poses fundamental challenges to the design of an effective resource allocation algorithm to maximize spatial reuse of spectrum, while maintaining basic fairness among multiple flows. When previously proposed scheduling algorithms have been shown to perform well in providing fair shares of bandwidth among single-hop wireless flows, they do not consider multi-hop flows with an end-to-end perspective when maximizing spatial reuse of spectrum. Instead, previous work attempts to break each multi-hop end-to-end flow into multiple single-hop flows for scheduling purposes. While this may be sufficient for maintaining basic fairness properties among single-hop subflows with respect to bandwidth, we show that, due to the intra-flow correlation between upstream and downstream hops, it may not be appropriate for maximizing spatial reuse of bandwidth. In this paper, we analyze the issue of increasing such spatial reuse of ba...
