摘要：For the reason of fast moving of the vehicles, the topology of Vehicular Ad-Hoc Networks (VANETs) dynamically changes and disconnections may frequently occur due to noise pollution. When two vehicles are disconnected, they are not able to access Information (Location, speed, vehicle identification) from each other. Information duplication has been widely used to decrease the effect of intermittent connectivity and improves Information access performance in distributed systems. When a vehicle leaves the group, it prefetches interested Information and transfers its buffered Information to other vehicles in advance so that they can still access the Information after it leaves. Mainly securing VANET application is very crucial to the implementation for this technology. Need to make sure that the vehicle is broadcasting a message is not a self-seeking or malicious vehicle. To face this problem, there is a need of a vehicle verification mechanism. Vehicle verification is though necessary to ensure the integrity, reliability and Security of the messages exchanged in the network. Network Simulator Version 2.0 (NS-2) is used to implementing this Mechanism. Extensive simulation results show that this method provides high Information availability, low Information access overhead, and Security.
