摘　　要：对车载自组织网络(Vehicular Ad-hoc Network,VANET)路由协议进行研究,通过对不同类型的现有路由协议的分析,特别是对基于强化学习和群智能算法的改进路由协议的分析,比较各类路由协议的工作原理、特点和适用场景。采用数据包投递率(Packet Delivery Rate,PDR)、吞吐量和延迟等3个评价指标对比和分析两种改进路由协议与基于拓扑、位置和分簇等3种路由协议在通信质量、数据传输效率和车辆分簇等方面的性能差异,以及存在的训练成本高和计算复杂的问题。The vehicular Ad-hoc network(VANET)routing protocol in vehicle self-organizing networks is studied.Through the analysis of different types of the existing routing protocols,especially the analysis of improved routing protocols based on reinforcement learning and swarm intelligence algorithms,the working principles,characteristics and applicable scenarios of various routing protocols are compared.Evaluation indicators such as packet delivery rate(PDR),throughput and delay are adopted to compare and analyze the performance differences among the two improved routing protocols and the 3 routing protocols,which are based on topology.location and clustering in terms of communication quality,data transmission efficiency and vehicle clustering.The problems of high training cost and complex calculation are also discussed.
