Detecting and revocation the compromised node in zone - based wireless sensor network using a two stage approach

Since the WSN is not secure in nature, it compromises the sensor node and the physical capture of these nodes is very easy for the intruder nodes. The intruder nodes simply communicate with any node in the zone, thus compromising the nodes and in turn spoiling the nature of the network. To reduce the damages be fallen on the compromised nodes, it should be successfully detected and revoked as soon as possible. Range of node specifies detection systems in wireless ad-hoc and sensor networks have been projected by academicians, of late. In the existing approach Leader based intrusion detection system is used to find out suspect regions where the compromised nodes are ensconced, here the Leader will be elected region wise based on the energy level to detect the attacker and revoke the compromised node. To overcome this as well as to provide high security two new stage approaches are proposed. They are the DPFM-[Data Packet Format Matching] method which detects the attacker node and DAA-[Divert Attention Attacker] method which prevents nodes compromising in the zone. The simulation result shows that the compromising node is eliminated and attacks are controlled in the network.
