摘　　要：移动自组织网络(MANETs)是无基础设施、由移动节点构成的动态网络。MANETs的移动特性给路由协议的设计提出挑战。为此,以典型的按需路由(AODV)为基础,提出基于链路稳定的MANETs路由协议,记为LSR。首先,分析了AODV的路由过程和不足,再计算节点能量寿命和链路寿命,然后通过比较能量寿命和链路寿命,构建候选转发节点集,最后,从链路稳定性角度,选择下一跳转发节点。实验结果表明,提出的LSR协议降低了路由开销,提升了吞吐量。与AODV相比,LSR协议的路由开销降低了近50%,吞吐量提高了23%。The mobile Ad Hoc networks(MANETs)composed of mobile nodes act as the dynamic network without infrastructure,and its mobile characteristic challenges the design of routing protocol.On the basis of the typical Ad Hoc on-demand distance vector(AODV)routing,the stable link based MANETs routing protocol(LSR)is proposed.The routing process and deficiency of AODV are analyzed,and then the energy lifetime and link lifetime of the node are calculated.The candidate forwarding node set is constructed by comparing the energy lifetime with link lifetime.The next?hop forwarding node is selected in term of link stability.The experimental results show that the proposed LSR protocol can reduce the routing overhead and improve the throughput.In comparison with AODV,the routing overhead of LSR protocol is reduced by 50%,and the throughput is improved by 23%.
