摘　　要：在无线Mesh网络中,针对短期优先级问题提出一种具有QoS保障的接入控制算法。当网络负载较重时,暂停低优先级业务的传输,给高优先级业务更多的接入信道的机会,为高优先级业务提供QoS保障。仿真结果表明,与IEEE802.11e EDCA相比,该算法可减小实时性业务的时延,提高系统吞吐量。Aiming at the short-term priority problem in Wireless Mesh Networks（WMN）, a medium access control algorithm with Quality of Service（QoS） guarantee is proposed. By suspending transmissions of low-priority traffic when traffic load is heavy, the proposed algorithm can provide more opportunities of channel access and QoS guarantee to high-priority traffic. Simulation results show that comparied with the IEEES02.11 e EDCA, this algorithm can reduce the delay of real-time traffic and improve the throughput.
