Joint channel assignment and routing protocol is critical to performance of multi-channel wireless mesh networks.On the basis of analyzing the characteristics and current works of joint channel assignment and routing protocols in multi-NIC multi-channel wireless mesh networks,a joint channel assignment algorithm combined with on-demand routing protocols is proposed,which achieves optimum by selecting channels with minimum of interference;a new routing metric that adapt to multi-channel multi-NIC network is also adopted,which take three key factors(channel interference,interface switching and path hops)into consideration.It is demonstrated in the simulation that the proposed protocol enhances netwok's throughput and reduces packet's end to end delay.
