Capacity and interference based channel assignment strategy for cognitive wireless mesh networks

To resolve channel interference problem in cognitive wireless mesh network, a distributed both capacity and interference based channel assignment and routing algorithm is proposed. First, selecting the lowest cumulative cost route effectively according to the new routing metric, and then, selecting the channel with the minimum interference-capacity ratio. Simulation results show that compared to the link-based and interference-based algorithm, the new algorithm has an obvious advantage in the performance of delay and throughput.
