中文摘要：
为应对无线网络通信路径耦合性和相互干扰的问题,提高无线网络通信性能,提出应用于城市环境车用自组织网络的多路径通信路由协议.根据城市环境道路网络特点,建立车用自组织网络多路径通信干扰模型;在此基础上提出基于交叉路口优化多路径通信路由,交叉路口附近的数据包基于多路径策略转发.实验结果表明,该多路径路由机制减少了数据冗余,有效避免数据碰撞,较大程度提高网络的数据包投递率并降低端到端延迟.
英文摘要：
Multipath communication schemes were proposed to optimize the performance of the vehicular Ad Hoc networks. Multipath routing can be used to improve the packet delivery ratio and reduce the end-to-end delay. However, the path coupling in wireless networks weakens the network communication performance. The urban multipath communication interference model was built based on the city road network characteristics. Then optimized multipath routing was proposed based on intersections. Packets were forwarded through multiple paths at intersections. The data redundancy of networks is reduced and the packet exponential explosion is avoided due to the convergence property of routing. Simulation results and performance analysis show that the proposed routing mechanism avoids data collision efficiently. It outperforms other existing routing protocols for vehicular Ad Hoc networks.
