Wireless Ad-hoc Sensor Network is an emerging platform in the field of remote sensing, data collection, analysis, rectification of the problem and research in various studies. The objective of this paper is to examine resource depletion attacks at the routing protocol layer, which attempts to permanently disable network nodes by quickly draining their battery power. This type of attack is called as vampire attack. These attacks are not specific to any protocol, but rather rely on the properties of many popular classes of routing protocols. 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. Methods to detect and secure data packets from vampires during the packet forwarding phase is discussed.
