摘　　要：近年来,车载自组织网络(VANET)快速发展,路由协议的准确分类归纳和对比分析对未来研究有重要的意义。针对VANET中路由协议归类分析不完善和未来发展趋势进行综述,依次从基于拓扑、地理和混合路由等方面进行分类归纳,着重介绍了一些经典的地理路由协议并对其特点和性能进行分析,提出了优缺点和改进意见。重点分析地理路由中未来研究热点的延时容忍路由(DTN)和机会路由协议,提出了VANET路由所面临的主要挑战和潜在的机遇,并指出明确的研究路径。In recent years, with the rapid development of Vehicular Adhoc NETwork （VANET）, wellclassified routing protocol and comparative analysis are important for future study. This paper dealt with the ambiguous classification and deficient analysis of the routing protocol in VANET, classifying and summarizing the routing protocols on the basis of topology, geography and hybrid route in turn. Mainly introducing some classical routing protocols, it analyzed their characteristics and performance, and put forward the advantages and disadvantages as well as improvements. Special stress was put on the comparative analysis of Delay Tolerant Network （DTN） and opportunity routing protocol which would become hot spots for future geographic routing study. Besides, the major challenges and potential opportunities that VANET was facing were pointed out, which had laid the foundation of future protocol study and suggested the path to research clearly.
