Secure Detection and Prevention Scheme for Jamming Attack in MANET

In MANET, secure routing is the major issue and it is difficult to identify malicious hosts as the topology of the network dynamically changes. In this paper we proposed the security scheme against jamming attack with AOMDV protocol. The proposed IDS scheme is identified the jammer attacker through the flooding of number of misbehavior control packets. These control packets are only consumes the network bandwidth and after some time it blocks the whole channel. Because of the mobility of the ad hoc network, a compromised node can frequently change its attack target and perform malicious behavior to different node in the network, thus it is very difficult to track the malicious routing behavior performed by a compromised node in network but the proposed scheme is identified it without any overhead in routing performance. The proposed IDS (Intrusion Detection System) security scheme is identified the attacker by their routing entry present on other nodes routing record. The attacker has dump the whole performing of network. The Multipath routing protocol AOMDV is provides the multiple path if the attacker is exist in established path. The infection from attack and performance metrics like throughput, routing load is evaluated and observe the secure proposed security scheme is immobilized the routing misbehavior of jamming attacker and provides secure AOMDV routing performance as equal to normal AOMDV performance.
