Abstract: Wireless sensor networks (WSNs) are the foremost promising research direction in sensing and pervasive computing. Previous security work has focused totally on denial of service at the routing or medium access management levels. Earlier, the resource depletion attacks are thought about solely as a routing drawback, very recently these are classified into new category as “vampire attacks”. Planned work examines the resource depletion attacks at the routing protocol layer that disable networks permanently by quickly debilitating node’s battery power. The new method for detecting Vampire Attacks is discussed in this paper.
