A Survey of Challenges in selection of Vehicular Mobility Models in VANET

With the recent advancement of technology, a new technology named VANET (Vehicular Adhoc Network) is emerging day by day. VANET is a wireless communication between vehicles to vehicles and RSU (vehicles to road side units). It is different from MANET, so the challenges of VANET are also different from MANET. It has many challenges like safety, traffic and user application based challenges which require some particular design. The vehicular mobility model plays a vital role in examining different challenges. There are different models for different purposes and for getting better results we have to apply the correct model which is suitable for the particular situation. In this paper, a proper classification is done between different vehicular mobility models with respect to their types, sub types, usage (interaction level), evaluating purpose and example of each model is also provided
