摘要:

结合VANET与信息中心网络(ICN,information centric network)架构,提出基于车辆动态信息的路由构造及筛选策略(SRBS,strategy for routing building and selecting)。摒弃了广泛采用的洪泛策略,通过内容发现定位内容节点,随后构造多个单播转发路径,减少了网络中的无用流量;为保证 Data 分组能够成功原路返回,在单播路径构造中引入车辆动态参数作为构造依据并结合链路有效时间(LET,link expiration time)进行路径筛选,提高了转发路径的稳定性及可靠性;仿真表明该方案提高了路由对时间的容忍度,充分利用了网络缓存并减少了网络时延及路由跳数。

Abstract:

Combining VANET with ICN,a routing building and selecting strategy-SRBS based on vehicular dynamic parameters was proposed.After locating the content nodes through content discovery process,several unicast forwarding paths would be built,which reduces useless traffic compared with a flooding way.By introducing dynamic metrics and LET to routing building and selecting process,SRBS improved the link stability and reliability,which ensured the Data’s successful return.Simulation results show the scheme also improves the time tolerance of routings and makes full use of network cache and reduces delay and routing hops.

Key words: VANET, ICN, vehicular dynamic parameters, LET, routing building and selecting
