Abstract: Using wireless Mesh networks to offer Internet connectivity is becoming a popular choice for wireless Internet service providers.However，the throughput obtained by different clients of same privileges can vary significantly depending on the hops from gateway，which is unfair.To guarantee users a fair share of the bandwidth，a new dynamic scheduling scheme based on multi-level queue（DSMQ） is proposed.The scheme is easy to implement.By dividing flows from different nodes into different queues，a dynamic scheduling scheme is adopted，and the flows achieve fair share of resources.The simulation results show the effectiveness of DSMQ，which realizes per-client fairness especially those long distance nodes and improves the performance of WMN.

摘要： 对因特网服务提供商而言，使用无线Mesh网络来提供因特网链接是一个日益普遍的选择。但是，因距离网关的跳数不同，等权限的不同用户间不能获取公平的网络资源。针对该情况，提出了多级队列动态调度机制（DSNQ）。该机制实现简单，将网络节点内部源点不同的数据流分列，引入动态调度机制，使节点内数据流公平共享信道资源。通过仿真验证了该机制的有效性，表明该机制实现了不同节点尤其是远端节点接入信道的公平性，改善网络整体性能。
