VANET-Challenges in Selection of Vehicular Mobility Model

Vehicular Adhoc Network (VANET) is wireless communication between vehicle to vehicle and vehicle to roadside infrastructure. The VANET has different challenges if we compare it with MANET. VANET has traffic, safety and user application based challenges which have some specific design requirements. To evaluate any VANET design, simulator with vehicular mobility model is required. Vehicular mobility model play a significant role in evaluating different challenges. It is found that different models are for different purposes. In fact Proper design with proper model is required for getting better results. A classification is made between different Vehicular mobility model on the basis of type, sub type, interaction level, and evaluation purpose with their examples.
