摘　　要：无线移动Mesh网络节点移动性和网络信道的抖动性会造成网络拓扑的变化及链路质量的不稳定等问题。节点间的链路生命期在一定程度上能够反映网络拓扑变化的强弱和路由的稳定度,通过建立移动参考模型、预测可持续通信距离,结合考虑链路度量长效性、短效性及移动性提出一种新度量方式,并提出一种更有效的路由协议LSM_AODV,该路由协议能够更加有效地适应无线Mesh网络路由场景。实验结果表明,与传统的AODV路由协议相比,基于位置预测和链路质量相结合的方法能够更好的地改善网络的性能,同时在时延和稳定性上提升10%~30%。The mobility of nodes and the jitter of wireless channel can cause the change of network topology and the instability of link quality in wireless mobile mesh network. In this paper,the lifetime of links between two nodes is analyzed by establishing the mobile reference model of nodes in wireless network and predicting the distance of sustainable communication,and then a new measure is proposed by considering the long-term,short-term and mobility of links. Long-short-term and Mobility AODV( LSM_AODV) routing protocol for wireless mobile Mesh network is designed based on mobility prediction. The experimental results show that compared with the traditional AODV routing protocol,the LSM_AODV routing protocol has significantly decreased the delay and improved the stability and effectively improved the network performance from 10% to 30%.
