Two Phase Methodology for the Detection of Malicious Vehicles from Vehicular Ad hoc Network

The vehicular ad hoc network is the decentralized form of network in which malevolent user can join the network which can trigger a variety of active and passive attacks. The denial of service is an active type of intrusion that is triggered by the malicious nodes present in the network. This research work introduces a new two-phase methodology for detecting and isolating the attack. In the first phase of the methodology tentative nodes will be analyzed which can be the malevolent nodes. The second phase confirms the nodes as spiteful nodes through the promiscuous mode. NS2 is applied to stimulate proposed technique and certain metrics are considered to compute the results.
