The mobility scenes of urban transport applications in the vehicular Ad Hoc networks is analyzed in this study. Based on the VanetMobiSim traffic simulator and NS-2 network simulator, two kinds of typical scenarios of urban intelligent traffic were built, which are Models of junction and two-way fast four-lane, and the AODV and DSDV routing protocols were simulated and analyzed in these two scenarios simultaneously. Four evaluation indicators which include end-to-end delay, jitter rate, packet loss rate, and control packet overhead, are introduced to evaluate and compare the performances of different protocols in the same scene. In addition, in the simulation experiments of AODV, the effects resulted from vehicle speed, vehicle density, the maximum number of connections, and the number of packets sending per unit time are also analyzed. The simulation result shows that selecting the appropriate mobility scene model helps to evaluate the performance of the protocols objectively, different protocols present different performance and adaptability in different scenarios. DSDV performs better when applied to simple and stable mobile scenarios, while AODV has better adaptability to complex and ever-changing mobile scenarios. Moreover, AODV protocol is greatly affected by the complexity of network topology and the frequency of the change in structure.
