基于不同VANET应用的路由协议选择分析

摘要

Different VANET applications have their requirements for the network attributes and respective characteristics,which influences the selection and using of routing protocols.Proper routing protocols will achieve better network performance and more efficient service.By analyzing 5 kinds of VANET application characteristics and network requirements,considering different types of routing protocols characteristics,this paper mainly elaborates selecting reasons for unicast and geocast.Structures of GPSR+AGF and CAR in unicast protocol are also given.%不同VANET应用对网络属性的要求和各自的特性影响路由协议的选择和使用。选择合适的路由协议将实现更好的网络性能，提供更高效的服务。通过分析VANET的5类应用的特点和对网络的要求，结合不同种类路由协议的特性，主要针对单播和多播情况下路由协议选择原因进行阐述，并给出单播协议中GPSR＋AGF和CAR这两种路由协议的构造方式。
