Vehicular Ad hoc NETwork (VANET) is the subgroup of the Mobile Ad hoc NETwork (MANET). VANET interconnects the nodes for transferring secure information between nodes; here vehicle acts as a node. VANET is used to provide safety and efficiency in transportation system. Many traffic signals are used to reduce accidents in the roads, but since it is not much effective. Hence VANET is used; it uses Road Side Unit (RSU). This RSU connects to the internet, and provides information to the vehicular ad hoc network users.
