摘要
描述了VANET的特点并在此基础上定义车载机会网络,提出一种基于热点的车载机会路由:VORI.该路由分为定向洪泛和反馈传输两部分,反馈传输部分使用了热点区域对贪婪算法进行了改进.路由方案中采取节点自学习方式调整路由参数,经开源模拟器ONE模拟实验结果验证,VORI与Epidemic、SprayAndWait等经典路由相比性能有较好的提升.
In this paper, the characteristics of VANET are described and vehicular opportunities network is defined. A Vehicular Opportunity Route Based On Real-time Information( VORI ) is proposed and it is consisted of directing data flooding and feedback transmisson. The feedback transmisson algorithm improves greedy algorithm by hot area. In this strategy router parameters are adjusted dynamically by nodes self-learning properly. The experiment result under open source simulator ONE shows that VORI works better than classic algorithmes such as Epidemic, SprayAndWait ,etc.
