Security and privacy are one of crucial factor in the area of information technology and iys applications. Ad-hoc network is a type of non-infrastructure wireless network that is more prone to be attacked and abused due to its properties. Deploying the ad-hoc network in vehicular environment needs the additional security consideration to prevent the attacks that can cause the serious harms like accidents, crashes and fatality of living being lives. In this paper we have explored analysis and requirements of the security solution for the ad hoc network under the vehicular environment. Different categories of threats, their risks are evaluated and then various issues related to deploying the security solutions are addressed by mentioning the proper security technologies and tools.

Mobile Ad Hoc Network is a infrastructure less wireless network where the mobile nodes leaves and joins the mobile network very frequently. The routing of the packets from source node to destination node, the routing protocol is used. On Demand Distance Vector Routing protocol is very common and implemented with Mobile Ad Hoc Network nodes to handle the operations of packet routing from by any node as a source node to destination node. In this paper prevention of black hole attack by modifying the On Demand Distance Vector routing protocol. The sequence number of 32 bit is initiated with the Route Reply and route sequence packet broadcast to determine the request reply from black hole node under the Mobile Ad Hoc Network. The sequence number and On demand Distance Vector Routing protocol are integrated with a mechanism to find the Request Reply of message containing routing information from source to destination node in Mobile Ad Hoc Network.
