| 摘 要： | 为保护无线局域网中高优先级业务的服务质量, 提出了一种基于请求发送(RTS)多预约和竞争窗口自适应调整的多优先级信道接入算法(MRDCW). 该算法首先利用RTS多预约进行优先级区分, 减少因低优先级业务增多而给高优先级业务带来的影响, 并通过理论建模验证了其有效性；其次, 不同等级的业务在竞争窗口回退时都根据自身的信道接入状况自适应调节竞争窗口大小, 以减小高优先级业务自身之间的影响. 仿真结果表明, 该算法相对802.11e更能适应网络状况的变化，并且更好地保护了高优先级业务的吞吐量.

| Abstract: | To protect quality of service(QoS) of high priority data stream in wireless local area networks(WLAN),a multi-priority algorithm named multiple reservation dynamic content window(MRDCW) is proposed.First,it adopts request to send(RTS) multiple reservation priority differentiating to decrease the influence to high priority data stream by low priority data load increasing,and then a model is built to verify effectiveness.Second,different priority access category adjusts self contention window adaptively based... |
