VANET中基于多属性决策的NDN道路拓扑转发策略
首发时间:2017-03-03
摘要:命名数据网络(Named Data Networking, NDN)是一种以内容为中心的新型未来网络架构,已有的研究表明该体系架构对于车载自组织网络(Vehicular Ad-hoc Network, VANET)有良好的适应性,NDN处处缓存的特点,使得兴趣包在转发时可能存在多个可选的目的节点,为此,本文设计了一种基于多属性决策的道路拓扑转发方案,通过多属性决策方法选取最优的目的节点,减少兴趣包盲目洪泛转发。仿真结果表明,该方案减少了兴趣包的平均请求时延,提高了数据的递交率,在VANET网络中有很强的应用性。

NDN Road Topology Forwarding Strategy Based on MADM in VANET
Abstract:Named Data Networking is a new future Internet architecture, which is based on contents. The recent research show that NDN architecture has good adaptability for VANET. The significant characteristic of NDN is caching everywhere, when interest packets are forwarded, the characteristic probably makes interest packet has several optional destination nodes. Therefore, this paper proposed a road topology forwarding strategy based on multiple attribute decision making method. Selecting the best destination node by multi-attribute decision. The simulation results show that the forwarding strategy reduce the average request delay of interest packets and increase Data delivery ratio, the strategy is applied to use in the VANET.
