摘　　要：V-NDN(vehicular named data networking)是一种使用命名数据网络架构的车辆自组织网络(vehicular Ad-hoc network,VANET),主要用来连接移动车辆之间的通信。提高网络中兴趣包的命中率是研究领域急待解决的难题。文章研究了城市道路环境下V-NDN的数据转发策略,考虑到城市道路环境下路侧单元(road side unit,RSU)被均匀广泛部署的特点,提出了一种基于RSU辅助的V-NDN数据转发策略(RSU aided V-NDN)。通过实验仿真与传统的V-NDN和基于蜂窝网络辅助的V-NDN进行对比,结果表明该文提出的数据转发策略有效地提高了网络的服务质量(quality of service,QoS)。Vehicular named data networking(V-NDN) is a vehicular Ad-hoc network(VANET) via named data networking, which is mainly used for networking vehicles on the run. How to improve the hit rate of the interest package in the network is a difficult problem to be solved in this field. This paper studies the data distribution strategy of V-NDN in urban road environment. Considering that road side unit(RSU) is evenly widely deployed in urban road environment, a RSU aided V-NDN data forwarding strategy(RSU aided V-NDN) is proposed. Compared with the traditional V-NDN and cellular aided V-NDN through experimental simulation, the results show that the proposed strategy and method effectively improve the quality of service(QoS) of the network.
