摘要
现有的车载网路由协议通常只利用车载网的单一特性进行路由设计,造成消息投递率过低或延迟过高。为此,提出一种整合专用短程通信与长期演进技术的异构车载网多属性决策路由协议。该协议在整合长期演进技术的基础上,以公交车辆与公交车站作为骨干网络,使用多属性决策的方法进行路由选择。仿真结果表明,与基于位置信息的贪婪边界协调者路由以及基于公交系统的距离向量路由相比,该协议能够有效地提高消息投递率并降低消息延迟。
Most exiting routing protocols in Vehicular Ad Hoc Network（ VANET） generally make use of a specific character of vehicular network,which leads to lowdelivery ratio or high delivery delay. In order to solve this problem,a multiple attribute decision making routing protocol which integrates both Dedicated Short Range Communication（ DSRC）and Long Term Evolution（ LTE） techniques is proposed for heterogeneous vehicular network. Integrating LTE and taking buses and bus stops as backbone,the newprotocol uses multiple attribute decision making method to choose route for message forwarding. Simulation results showthat this protocol can efficiently boost delivery ratio and decline delivery delay compared with the geographical Greedy Perimeter Coordinator Routing（ GPCR） protocol and public transport based Distance Vector Routing（ DVR） protocol.
