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.
The characteristics of VANET are described and the on-board opportunistic network is defined on the basis of which a hot opportunity-based on-board opportunistic route is proposed: VORI. The route is divided into two parts: directed flooding and feedback transmission. The feedback transmission uses the hot spot algorithm for greedy algorithm The route parameters are adjusted by node self-learning in routing scheme, which is verified by open source simulator ONE simulation results. VORI has better performance than classic routes such as Epidemic and SprayAndWait.
