车联网络车辆结点路由算法研究OA

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.
