| 摘 要： | 采用复杂网络理论研究VAENTs网络动态拓扑结构特性，以基于车辆换道功能的智能驾驶移动模型为
基础，应用VanetMobiSim仿真软件建立了车辆交通网络，详细分析了VAENTs网络瞬时拓扑特征及平均度、聚类系数和调和平均最短路径长度等复杂统计参数随时间的变化特征。通过仿真实验发现VAENTs网络动态拓扑不具有无标度属性，只在特定条件下，才呈现小世界网络的特征。

| Abstract: | This paper, the dynamic topology of the vehicular network was investigated using the perspective of complex network. In order to simulate vehicle movement, vehicular network with intelligent driver model with lane changes (IDM-LC) is set up by VanetMobiSim software. The instantaneous topology and the statistics of the degree distribution, clustering coefficient and harmonic mean minimal path length of VANETs were analyzed. The results show that VANETs do not have the properties of scale-free property and exhibit small-world properties under the specified conditions. |
