A cluster based intrusion detection and prevention technique for misdirection attack inside WSN

Constrained resources, the ad-hoc nature of deployment and the vulnerability of wireless media are some of the most challenging characteristics of Wireless Sensor Network (WSN) which pose a need for unique security solutions. WSNs are susceptible to various attacks, in which Misdirection a kind of Denial of Service (DoS) attack is very difficult to detect and defend. In Misdirection Attack, the intruder misdirects the incoming packets to a node other than the intended node which introduces high end-to-end delay (sometimes infinite) in the network. The performance of the network (i.e. throughput) is also degraded. Thus the detection and prevention of this attack becomes very crucial. In this paper we have proposed a novel Cluster Based Intrusion Detection and Prevention Technique for Misdirection Attack. The network parameters calculated by the use of this technique shows considerable amount of improvement in throughput while introducing small amount of delay.
