Aiming at the network characteristic of wireless Mesh networks(WMN),the EDCA algorithm in WMN is ana-lyzed,and a fairness-based EDCA algorithm is provided. The implementation process and the rule of parameter variation are dis-cussed. Through simulation,the algorithm is proved to have the characteristic of improving the fairness of the network while per-fecting the network performance. What′s more,it can also realize the differentiation of different service.
