Cognitive Radio Based Routing Protocol for Multi-channel Wireless Mesh Networks
Quan Gang Yu · 2012
In multi-channel wireless mesh network,there is tight inter-dependence between route selection and availabi-lity of spectrum,so selection of channel is required to be fully considered when designing routing protocol.Traditional routing protocol can't be well applied to cognitive radio network.The proposed routing protocol,in which each node is equipped with dual network interface,achieves routing selection and channel selection simultaneously,and takes advantage of multiple channels with collision avoidance design.Simulation shows that the proposed protocol,compared to traditional routing protocol,can significantly improve throughput of the network.
