【摘要】：针对车载自组织网络(VANET)拓扑结构的动态性特征,基于车辆换道功能的智能驾驶移动模型,应用Vanet Mobi Sim仿真软件详细研究车载自组织网络拓扑结构的动态中心性。构建VANET时序网络模型,建立基于衰落因子和信息存储转发指数的动态中心性评价方法,该方法不仅能够描述当前网络拓扑与历史网络拓扑之间的联系,而且能够刻画VANET中信息的存储转发机制;最后,通过仿真实验分析了VANET动态中心性。结果表明虽然VANET拓扑结构的动态中心性随着衰落因子和信息存储转发指数的变化而变化,但重要节点整体的排名基本保持相对稳定的状态。该结论有助于更好地确定信息传播的中继节点,实现信息的成功投递,而且为VANET拓扑结构的抗毁性提供指导。
[Abstract]:In view of the dynamic characteristics of the vehicle-borne ad hoc network (VANET) topology, the dynamic centrality of the vehicle-borne ad hoc network topology structure is studied in detail by using Vanet Mobi Sim simulation software, which is based on the intelligent driving movement model of the vehicle switching function. The VANET temporal network model is constructed and the dynamic centrality evaluation method based on fading factor and information storage and forwarding index is established. This method can not only describe the relationship between the current network topology and the historical network topology. Moreover, it can describe the mechanism of information storage and forwarding in VANET. Finally, the dynamic centrality of VANET is analyzed through simulation experiments. The results show that although the dynamic centrality of VANET topology changes with the change of fading factor and information storage and forwarding index, the overall ranking of important nodes remains relatively stable. This conclusion is helpful to better determine the relay nodes of information transmission, to realize the successful delivery of information, and to provide guidance for the survivability of VANET topology.
