中文摘要:
      车辆命名数据网络(VNDN)是将命名数据网络(NDN)与车辆自组织网络(VANETs)有机结合起来的一种新型网络架构,其信息共享方式由传统网络的地址转变为内容。当前的VNDN网络中,车辆查找内容主要通过泛洪兴趣包的方式,会消耗较多的网络资源,造成大量延迟。针对此问题,提出了一种基于多准则决策的兴趣包转发方法,该方法借鉴TOPSIS理论优势,选择特定车辆转发兴趣包,从而有效利用了网络资源。实验结果表明,所提方法在车辆获取特定信息时,在网络时延以及丢包率方面均体现出一定优势。
英文摘要:
      Vehicle Named Data Network (VNDN) is a new network architecture combining Named Data Network (NDN) and Vehicle Ad-hoc Network (VANETs), and its information sharing mode is changed from address to content. In the current VNDN, vehicle search content is mainly through flooding interest packets, which will consume more network resources and cause a lot of delay. To solve this problem, a interest packet forwarding method based on multi-criteria decision making is proposed. The method uses TOPSIS theory to select specific vehicles to forward interest packets, thus effectively utilizing network resources. Experimental results show that the proposed method has certain advantages in network delay and packet loss rate when the vehicle obtains specific information.
