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...
Cognitive radio, which enables dynamic access of under-utilized licensed spectrums, is a promising technology for more efficient spectrum utilization. Since cognitive radio enables the access of larger amount of spectrum, it can be used to build wireless mesh networks with higher network capacity, and thus provide better quality of services for high bit-rate applications. In this paper, we study the...
Many efforts have been devoted to maximizing network throughput in a multi-channel multi-radio wireless mesh network. Current solutions are based on either pure static or pure dynamic channel allocation approaches. In this paper, we propose a hybrid multi-channel multi-radio wireless mesh networking architecture, where each mesh node has both static and dynamic interfaces. We first present an Adaptive...
