| 摘 要： | 随着无线Mesh网络(WMN)中跳数的增加,端到端的延时急剧增大,所以,在多跳WMN中很难做到服务质量(QoS)保证。针对以上问题,提出了一种新型多信道时分多址(TDMA)媒体访问控制(McTMAC)的协议,可以有效地降低在多跳网络中端到端的延时。通过测试评估结果显示:McTMAC协议优于现有的无线WMN协议,通过使用McTMAC协议端到端最大延时降低了60%。

| Abstract: | With the increasing number of hops,it is difficult to guarantee QoS over multihop wireless mesh networks（WMN） because end-to-end delay increases quickly.To solve the above issues,a novel multi-channel time-division multiple-access（TDMA） media access control（MAC）,that is McTMAC protocol that can help to efficiently reduce end-to-end delay over multihop networks.Performance evaluation results demonstrate that McTMAC outperforms existing WMN protocols,the maximum-delay can be reduced by as much as 60 ％ by using McTMAC protocol. |
