Wireless sensor networks are an exciting research direction in sensing with various parameters like security, energy. Most of the prior security work has done with denial of communication at the routing or medium access control levels. This paper mainly focuses on resource depletion attacks that are draining of battery life of the sensors at the routing protocol layer, which results in quickly draining nodes battery power. Vampire attacks do not have any architecture that is attacks are not specific to any specific protocol. In the worst case, a single Vampire can increase network-wide energy usage by a factor of O(N), where N in the number of network nodes.
