A new routing protocol in cognitive wireless mesh networks

An innovative routing protocol named AODV-COG is proposed in this paper. Our protocol not only assign an appropriate interface to a route to efficiently make use of the spectrum in cognitive wireless mesh networks but also select an appropriate path which brings high-throughput to route packets. The proposed routing protocol is based on the classic AODV protocol and requires some changes to the NS-2 simulator to simulate the cognitive wireless mesh network conditions. Based on simulation results, AODV-COG successfully exploits the dynamic spectrum to improve the throughput of the network and does well in finding a path with higher throughput among the paths with the same hop counts.
