Mesh network, fairness, throughput, chain topology, scheduling.
In wireless mesh networks (WMN), each node operates not only as an access point but also as a router that forwards user frames to and from a gateway which is connected to the Internet. It has been shown that there is a fairness prob lem in such wireless mesh networks in that nodes farther away from the gateway may be starved by nodes closer to the gateway. In this paper, the end-to-end fairness problem in a chain topology is first analyzed. A solution consisting of Token-based Distributed Scheduling (TDS) and per-flow queuing is then proposed to avoid nodes being starved and to improve the total flow throughput.
