Mitigation of Vampire Attacks in Wireless Sensor Networks

Abstract

Ad-hoc sensor network and routing data in them is a most significant research area. There are lots of protocols established to protect from DOS attack, but it is not perfectly possible. One such DOS attack is Vampire attack. This vampire attack is a resource depletion attacks at the routing protocol layer, which permanently disconnect the networks by quickly draining nodes’ battery power. These “Vampire” attacks are not specific to any specific protocol, but rather depend on the characteristics of many popular classes of routing protocols. This project illustrates a technique to tolerate the attack by employing the Cluster Head. In case of each Vampire attack, the Cluster Head employs in this situation and distributes the packet to destination without dropping the packet. Thus give a successful and reliable message delivery even in case of Vampire attack. In the worst case, a single Vampire can increase network wide energy usage by a factor of O(N), where N is the number of network nodes.
