Technique to Detect and Isolate Jamming Attack in VANET

The vehicular ad hoc network is the decentralized type of network in which mobile nodes can communicate with each other. Due to self configuring nature of the network malicious nodes join the network which are responsible to trigger various types of active and passive attacks in the network. The jamming attack is the active type of attack in which malicious node select the nodes which will be controlled by the malicious node. The selected nodes are responsible to flood the victim node with the rough data packets. In this work, threshold based technique has been proposed in which node which is sending data above the threshold value will be responsible to trigger jamming attack in the network. The proposed technique has been implemented in NS2 and it has been analyzed that proposed technique performs well in terms of throughput, delay and packet loss.
