摘　　要：设计一种基于地理位置和结点信任值的车联网络路由算法。路由算法在传输数据时,首先通过信标广播获得目的地结点的地理位置信息和邻居结点的地理位置信息,然后结点根据收集到的地理位置信息调用转发算法进行数据包转发。路由算法使用两种转发策略,贪婪转发策略和修正转发策略,通过实验仿真获得特定情境下路由算法的平均端到端时延和丢包率,分析车辆结点数目和车辆结点最大速度对路由算法性能的影响。A routing algorithm of Vehicular Ad Hoc Network based on geographical location and node trust value is designed.When transmitting data,the routing algorithm first obtains the geographical location information of the destination node and the neighbor node through beacon broadcasting,and then the node calls the forwarding algorithm to forward the data packet according to the collected geographic location information.The routing algorithm uses two forwarding strategies,greedy forwarding strategy and modified forwarding strategy,and obtains the average end-to-end delay and packet loss rate of the routing algorithm in a specific situation through experimental simulation.The effects of the number of vehicle nodes and the maximum speed of vehicle nodes on the performance of the routing algorithm are analyzed.
