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.
