Providing High Security in User for Vehicular Ad- Hoc Network

S.Manoranjitha, M.Vasanthi

Vehicles have to be prevented from the misuse of their private data and the attacks on their privacy. Investigate the authentication and privacy issues in VANETs. The architecture of vehicles are dynamically clustered according to different related metrics from these clusters, a minimum number of vehicles are selected as vehicular gateways to link VANET. Issues pertaining to gateway selection, gateway advertisement and discovery, service migration between gateways when exchanging messages between vehicles, there are network issues that must be addressed, including the hidden terminal problem, high density, high node mobility, and data rate limitations. Vehicles (users) and a Regional Trusted Authority, we consider a VANET consisting of a city lay and highway, finite numbered registered RTAs nodes along roads and a large number of vehicles on or by the roads. RTAs are always reliable, while vehicles on city ride and in highway ride is used analyze the various metrics and compared with different routing protocols such as AODV, DSDV, DSR in simulation.
