A realistic Mobility Model for urban traffic scenario in Vehicular Delay Tolerant Network

The vehicular mobility models have great significance and serious effect on simulation of Vehicular Delay Tolerant Networks. Most of the existing vehicular mobility models can be classified into synthetic mobility models. Though being widely applied, they do not properly reproduce complex urban traffic environment. To improving the vehicular mobility model´s reality, this paper analyzed real-world vehicular trace and proposed Real Trace Vehicular Mobility Model with introducing of the traffic flow theory. This model incorporated resident area and more realistic speed rule. On this basis, the further analysis of the proximity of the model, the statistical characteristic and the network connection characteristic are given in this paper. The simulation results show that the proposed model can properly approximate the actual vehicular behaviour in urban traffic scenario.
