With the development of intelligent transportation systems, more and more attention was paid to the study of VANETs. A reasonable node mobility model is very important to evaluating the authenticity of various VANETs protocols. In this paper, a mobility model based on real map was proposed for VANETs to overcome the disadvantages of existing models.
The new model can show vehicles’ movement scenario more veritably in routing selection, movement direction of nodes restricted by roadnetwork, etc. Simulation results show that this model reflects VANETs performance properly, and it is valuable on studying and evaluating protocols for VANETs.
