车载网运动模型的复杂网络解析方法

摘要

车载网快速移动的特点导致其结构具有强烈的复杂性,传统的网络研究方法无法对这种复杂性进行分析.针对此问题将复杂网络解析方法运用于车载网的研究之中,依据车载网组网过程建立车载网运动模型,通过复杂网络研究手段与运动模型相结合的方式对车载网的度分布、鲁棒性以及网络连接变化率进行分析与仿真实验.结果表明,所构建的运动模型能够反应车载网构网过程,复杂网络解析方法在车载网性质分析方面十分有效.%The fast-moving characteristic of VANET(Vehiche Ad-hoc NETwork) leads to a high complexity of network structure that the conventional methodology of network cannot figure out.The solution proposed was based on the complex networks theory since its applicability is straightforward for this high complexity of VANET.And a mobility model was also proposed based on the process of network construction of VANET.The combination of the complex networks theory and the mobility model can be used to analyze the degree distribution,robustness,and the rate of connection change of VANET.Meanwhile,the method be simulated and validated.The results show that the proposed mobility model can represent the process of network construction of VANET,and the complex networks theory is very effective in its property analysis.
