Mitigation of Jamming Attack in Vehicular Ad hoc Network

Vehicular Ad-hoc Network (VANET) is taking more attention in automotive industry due to the safety concern of human lives on roads. Security is one of the safety aspects in VANET. To be secure, network availability must be obtained at all times since availability of the network is critically needed when a node sends any life critical information to other nodes. However, it can be expected that security attacks are likely to increase in the coming future due to more and more wireless applications being developed and deployed onto the well-known expose nature of the wireless medium. In this respect, the network availability is exposed to many types of attacks. In this paper, jamming attack on network availability is presented and also provide a RTS/CTS mechanism to mitigate the jamming attack in VANET. A model to secure the VANET from the jamming attacks has been developed and gives a possible solution to overcome the attacks have been discussed.
