Framework of Real VANET Simulation Research

Vehicular Ad hoc Networks (VANETs) has a high node mobility speed, frequently changed network topology and limited node movement directions. Simulation is the main method that obtained in the VENET's research. The simulation of VANET includes two main parts: the built of vehicular mobility model and the simulation of self-organizing wireless mobile network. The authenticity of network simulation result is largely determined by the authenticity of the vehicular mobility model. This paper analyzes the category of vehicular mobility models, concludes the basic method to build vehicular mobility models, introduces SUMO as a vehicular mobility model building software and outlooks the future development of VANET simulation technology.
