A mobility model based on traffic flow theory for Vehicular Delay Tolerant Network

The choice of the mobility models affect seriously the simulation results of the key technologies for Vehicular Delay Tolerant Networks. Most of the existing vehicular mobility models can be classified into synthetic mobility model which do not conform to the real scenario. With the real vehicular trace, this paper proposed realistic vehicular mobility model based on traffic flow theory which has considered the road topology, the vehicular speed rules and the routing selection. On this basis, this paper analyzed the model's proximity of the actual vehicular behaviour, this model's statistical characteristic and network connection characteristic. The simulation results show that the proposed model can properly approximate the actual vehicular behaviour in urban traffic scenario.
