A Novel Proposal for Defending against Vampire Attack in WSN

Wireless sensor network is a communication network across the sensors nodes. A sensor node collects information about the physical environment. Now-a-days one main issue in wireless sensor network is wastage of energy at each sensor nodes. Energy is the one most important factor while considering sensor nodes. One new type of attack called vampire attack, which occurring at network layer. It leads to resource depletion (energy) at each sensor nodes, by reducing the battery power of any node. We propose method to mitigate this type of attack. This paper focuses on the goal of detection of vampire attack. The proposed method prevents the draining of life from network nodes. It works on the threshold energy of node. Thus, the problem of vampire attack can be reduced to some extent.
