摘　　要：以优化的链路状态路由(Optimized Link State Routing,OLSR)协议为原型,为无线移动自组织网络(Mobile Ad Hoc Networks,MANETs)设计了基于跨层的速率自适应的加权路由协议。该协议充分考察无线信道的时变性质,在路由计算过程中通过跨层信息共享节点的邻居关系及获取节点的当前发送速率,削减了协议的开销。将无线链路的速率与跳数相结合,设计了一种新的路由度量规则。仿真结果表明,提出的加权路由协议能够显著降低网络层的路由开销,提升网络吞吐量,降低端到端时延。A weighted routing protocol based on cross-layer rate adaptive is designed for MANETs(Mobile Ad Hoc Networks),which uses OLSR(Optimized Link State Routing)as a prototype.The protocol fully examines the time-varying nature of wireless channel and reduces the overhead by sharing the neighbor relationship of the nodes and obtaining the current transmission rate through cross-layer information in the process of routing computation.A new routing measurement rule is designed by combining the rate of wireless link and hop number between the source and destination nodes.Simulation results indicate that the proposed weighted routing protocol can significantly reduce the routing overhead at the network layer,improve the network throughput,and reduce the end-to-end delay.
