嵌入式环境下基于AODV的VANET通信机制研究

Research on communication mechanism of VANET based on AODV in embedded environment

车载自组织网络(Vehicular Ad Hoc Network,VANET)技术为人类实现智能交通提供了技术保障.作为VANETs的重要组成部分,路由协议的好坏决定了网络的性能.研究了在Linux嵌入式环境下AODV路由协议的实现方案,完成无线自组织网络车载平台的设计.在真实场景下,测试其连通性以及路由性能.实验结果表明,该无线自组织网络平台在往返时间以及丢包率方面具有良好的性能.

Vehicle Ad Hoc Network(VANET)technology provides technical support for human beings to realize intelligent transportation. As an important part of VANETs,the routing protocol determines the performance of the network. This paper studied the implementation of AODV routing protocol in Linux embedded environment. Complete the design and verification of wireless Ad Hoc Network vehicle platform. In the real scene,the connectivity and routing performance was tested.Experimental results showed that the wireless Ad Hoc Network platform has good performance in round-trip time and packet loss rate.
