摘　　要：为解决认知无线mesh网络中的信道干扰问题,提出了一种基于容量与干扰的分布式信道分配和路由算法。首先根据路由度量有效地选择最低累积代价路由,再根据信道干扰容量比最小化来选择信道。仿真结果表明:所提算法与基于干扰、基于链接的算法相比,能够显著改善平均吞吐量和时延等网络参数性能。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.
