摘　　要：为了提高无线Mesh网络路由协议的吞吐量和传输质量,提出了一种跨层路由协议MCL-AODV。该协议通过跨层操作机制综合考虑MAC层链路质量、节点队列拥塞度和无线传输距离对链路性能的影响,创建复合路由判据以优化路由选择过程;通过改变HELLO消息触发机制降低路由管理控制开销。仿真结果表明,MCL-AODV降低了平均路由开销、减小了端到端时延,提高了网络吞吐量和分组投递率。To improve the throughput and transmission quality of routing protocols for Wireless Mesh Networks, this paper presents a cross-layer routing protocol MCL-AODV for the wireless Mesh back- bone networks. By taking MAC layer link quality, congestion of the node queue and wireless trans- mission distance into account, the proposed algorithm optimizes the routing process by creating a new routing metric and reduce the routing overhead of management control by changing the trigger mechanism of HELLO message. Simulation results show that MCL-AODV protocol reduces the aver- age routing overhead and end-to-end delay, and improves network throughput and packet delivery ratio.
