摘　　要：在移动自组织网中由于节点的移动性引起网络拓扑变化,成为影响网络性能优劣的关键因素。在反应式路由算法的基础上,提出了一种基于节点位置、速度与方向混合参数的路由协议AODV-PVD(AODV Routing Protocol based on Node Position,Velocity and Direction)以衡量链路稳定性并预测链路持续时间。在路由发现阶段,根据节点的混合运动信息,使用节点筛选机制排除相对不稳定的链路,并通过节点相对移动速度预测链路持续时间,为数据传输选取稳定且路径较短的路由。NS2仿真结果显示,相较于按需距离矢量路由AODV(Ad Hoc On-demand Distance Vector)及现有改进协议,AODV-PVD路由协议可以获得更好的分组投递率、端到端传输时延和吞吐量性能。In the Mobile Ad Hoc network,the network topology change caused by the mobility of the nodes becomes the key factor affecting the network performance.On the basis of reactive routing algorithm,an AODV Routing Protocol based on node position,velocity and direction(AODV⁃PVD)is proposed to measure the link stability and predict the link duration.In the route discovery stage,according to the mixed motion information of the nodes,the node screening mechanism is used to exclude relatively unstable links,and the relative movement speed of the nodes is used to predict the link duration,so as to select a stable and short route for data transmission.The NS2 simulation results show that,compared with ad hoc on demand distance vector(AODV)and existing improved protocols,the AODV⁃PVD routing protocol can achieve better performance on packet delivery rate,end⁃to⁃end transmission delay and throughput.
