The increasing demand of wireless communication and the needs of new wireless devices have tend to research on self organizing, self healing networks without the interference of centralized or pre-established infrastructure/authority. Vehicular Ad hoc NETworks (VANETs) is the subclass of Mobile Ad hoc NETworks (MANETs). The communication may be of 3 types: inter-vehicle communication, vehicle to roadside communication and inter-roadside communication i.e. communication between roadside unit and the base station. Network connectivity is the key factor for frequent link breakage and high mobility of vehicles as it greatly affects the VANET performance.
