摘　　要：提出了802.11s无线Mesh网络中协作多样性感知的路由度量,并提出了适应无线Mesh网络特点的协作式路由协议(CDARP)与协作媒体访问控制协议(CMAC).通过构建协作虚拟节点、计算协作链路度量,CDARP-CMAC能够选择最合理的路径进行协作数据传输.实验结果表明,与最优路径的协作机制相比,CDARP-CMAC协议提高了网络有效吞吐量5%～13%;同时降低了数据包丢包率5%～10%.A cooperation diversity-aware routing metric for 802.11s-based wireless Mesh networks（WMNs） is proposed.Furthermore,a cooperation diversity-aware routing protocol（CDARP） and a cooperative MAC protocol（CMAC） are proposed,and both the protocals are adapted to the characteristic of WMNs.By building up virtual nodes and calculating the routing metric for virtual links,CDARP-CMAC can select the most reasonable path to cooperatively transmit packets.The simulation results show that,compared to the traditional cooperation scheme,CDARP-CMAC improves the good put by 5%~13% and reduces the drop rate by 5%~10%.
