摘　　要：为适应"绿色交通"的潮流、深入研究车载网网络演化规律,基于城市VANET实证数据,建立一种网络动态演化模型。结合车载网自身特点,以收集的上海市4000多辆车辆的真实数据为样本,分析车载网的演化过程和连通性,进而解释其对应的网络行为。模型从确定图形链接方式出发,利用小世界等网络链接特性,充分发挥出随机和优先链接在网络演化中的优势。通过仿真实验,验证车载网网络演化的规律性及动态演化模型的有效性,为车载网网络的分析与管理提供助益。In order to adapt to the trend of "green transportation" and deeply study the evolution of vehicle network,a network dynamic evolution model is established based on the empirical data of VANET.Based on the characteristics of on-board network and the real data of more than 4000 vehicles collected from Shanghai,the evolution process and connectivity of on-board network is analyzed,and then its corresponding network behavior is explained.Starting from the way of graphic link,the model makes full use of the characteristics of network links such as small-world to give full play to the advantages of random and preferential links in network evolution.Through the simulation experiment,the regularity of network evolution and the validity of the dynamic evolution model of vehicle network are verified,which is helpful for the analysis and management of vehicle network.
