摘　　要：对无线Ad-Hoc网络(MANET)路由协议作了简要介绍和比较,在动态路由协议(DSR)的基础上,提出基于路径稳定性和最短性的混合度量路由协议(MDSR)。该协议由移动节点的位置、速度和移动方向等信息来预测相邻节点有效通信时间,然后结合路径跳数,运用混合度量模型选择最佳路由。仿真结果,一方面证明了MDSR比DSR有较低的控制包开销和较高的包投递率,另一方面也说明了混合度量是路径选择的最佳度量。This paper Introduces the routing protocol of MANET and compares it with others,a routing protocol with the mixed routing metrics of stability and shortness,which is named as MDSR（mixed DSR）,is proposed on the basis of the dynamic source routing（DSR）.It predicts the valid communicating time of adjacent nodes by such information as the position ,velocity and moving direction of moving nodes ,and using the hops ,selects the best path with the mixed-metrics model.The simulation shows that MDSR has lower control overhead and higher package delivery rate than DSR,on the other hand ,the mixed metrics are the best selection of routing metrics.
