Abstract
To resolve channel interference problem in cognitive wireless mesh networks
a distributed capacity and interference based channel assignment and routing algorithm is proposed.The lowest cumulative cost route is effectively selected according to the new routing metric.The channel is selected according to 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 time delay and average throughput.
