A New Handover Scheme for Providing Security in VANET

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. Each and every vehicle is interconnected to each other hence it can send alert message to another vehicle to reduce the speed or increase the speed to avoid accidents. Each and every vehicle can use internet facility while traveling. Since mobile internet is used nowadays but this road side unit internet connection is more speed. The information transferred between vehicle and RSU is more secure, because the road side unit provides unique key for each and every user connected to it. When the vehicle is moved out of the particular range, handover scheme occurs. The bending information will be transferred from old RSU to the new RSU. The service provided by the road side unit is called Service-Oriented Vehicular Ad Hoc Network.
