Aiming at the network characteristics of wireless Mesh network, this paper analyzes the EDCA algorithm in Wireless Mesh Network (WMN) and proposes a CPEDCA algorithm based on the probability of congestion. The detailed implementation process of the algorithm and the dynamic adjustment of parameters are discussed in detail. The algorithm improves the performance of the network and at the same time can differentiate the services among different service flows.
