In recent years, multi-channel multi-radio Wireless Mesh network has become one of the most important technologies in the evolution of next-generation networks. Its multi-hop, selforganization, self-healing and simple deployment is an effective way to solve the bottleneck problem of last mile. In this paper, we propose a new routing metric called WAEED, deployed in JCWAEED protocol, a joint channel assignment and weighted average expected end-to-end delay routing protocol which considers both interference suppression with factor IF and end-toend delay. Additionally, we give the exact calculation formula of transmission delay and queuing delay. Simulations results demonstrate that JCWAEED outperforms other joint design routing protocols in terms of throughput, end-to-end delay and packet loss rate.
