In this paper, we present fast converging algorithms that fit well WiMAX mesh networks. First, a centralized scheduling algorithm is presented. It calculates schedules by transforming the multi-hop tree into a single hop, and then repartitioning the different schedules in the multi-hop tree. Second, a routing metric called Multiple Channel One Pass (MCOP) is introduced. MCOP chooses routes by explicitly accounting for the coding and modulation schemes on each route as well as the number of available channels. In addition, the route construction is performed in a way that reduces the impact of the bottlenecks on throughput. Numerical simulations show the superior performance of MCOP as compared to other routing metrics especially when the available number of channels is more than two.
