摘要
首先对车联网网络分割的判定方法、发生网络分割的可能性进行了分析。在分析的基础上,为了解决车联网中由于网络拓扑结构的动态变化引起的网络分割的问题,提出了一种基于行车参数信息的车联网网络分割解决方法。方法利用GPS定位装置提供的行车参数信息,对网络分割解决过程中目标节点的移动轨迹进行了预测并对目标节点位置进行修正。仿真结果表明该方法有效降低了网络端到端的延时,提高了网络分割修复成功率和分组转发成功率。
Firstly, the judgment method of the network partition for vehicular ad hoc networks and the possibility of the network partition are analyzed in the paper. On the basis of the analysis, to solve the problem of network parti- tion for vehicular ad hoe networks caused by the dynamic change of network topology, a solution of the network par- tition for vehicular ad hoc networks based on driving parameters is proposed. Using the driving parameters informa- tion provided by the GSP positioning device, the method can predict the movement and modify the position of the target node in the process of the network partition. The simulation results show that the method can reduce the end- to-end delay of network, and improve the success rate of network partition recovery and the packet forwarding.
