| 摘 要： | 文中在分析车辆移动的规律性和车辆在路网中非均匀分布特点的基础上,提出了车辆网络场景下的机会式路由VNS-OR.通过路段延时估计,为消息在源位置至目的位置确定最短延时传输路径.按该路径传输时,在节点密集分布路段采用多跳转发,在节点稀疏分布路段采用携带转发的路由策略.实验表明,VNS-OR路由可以满足车辆网络场景下时延容忍数据的传输需要.

| Abstract: | On the basis of analyses of the mobility and non-uniform distribution of vehicular in the road,the opportunistic routing algorithm,VNS-OR,for vehicular network scenario is proposed.With the time delay estimation in road section,the shortest delay transmission route form source location to the destination is determined.Packets are sent by multi-hops in dense road sections and by store-carry-forward in sparse road sections along this route.The simulation experiments show that VNS-OR can meets the delay tolerant in vehicular network scenario. |

| Keywords: | vehicular network scenarios time delay estimation shortest delay transmission route store-carry-forward delay tolerant |
