Maximizing Lifetime of Nodes in Wireless Ad Hoc Sensor Network by Preventing Vampire Attack

A.Vincy, V.Uma Devi

Ad-hoc sensor network and routing data in them is a significant research area. There are a lot of protocols developed to protect from DOS attack, but it is not completely possible. One such DOS attack is Vampire attack-Draining of node life from wireless ad-hoc sensor networks. This explores resource depletion attacks at the routing protocol layer, which permanently disable networks by quickly draining nodes‟ battery power.The Vampire attacks are not exact to any specific protocol.The Vampire attacks, which are not easy to detect. The proposed approach consists of two phases. In the first, phase detecting and preventing denial of service attack based on secret sharing(SS) algorithm. In the second phase, increasing network lifetime based on switching the node states. The data verification process is provided at both the server and client side. It provides comparatively high security. It reduced the intruder spoofing.
