Abstract: Wireless mesh networks allow multiple orthogonal channels to be used simultaneously in the system to improve the throughput, but interference still can' t be avoided. The paper studied TDMA-based timeslot allocation to schedule links efficiently, and presented an effective heuristic algorithm for calculating end-to-end bandwidth on a path,which is used together with AODV to setup QoS routes. Simulation results show that compared with the shortest path routing, our interferenccaware QoS routing algorithm always increases success ratio of finding a route with required bandwidth to destination node.
