Wireless Mesh Networks (WMNs) built with commodity 802.11 radios are a cost-effective means of providing last mile broadband Internet access. Their multi-hop architecture allows for rapid deployment and organic growth of these networks. In this paper, the authors focus on fair rate allocation requirements. Their approach does not require any changes to individual mesh routers. Further, it uses existing data traffic as capacity probes, thus incurring a zero control traffic overhead. They propose the mechanism based on this approach on Aggregate Rate Control (ARC). ARC limits the aggregate capacity of a network to the sum of fair rates for a given set of flows.
