Wireless sensor network is a communication network across the sensors nodes. Sensor nodes collect information about the physical environment. Now-a-days one main issue in wireless adhoc sensor network is wastage of energy at each sensor nodes. Energy is the one most important factor while considering sensor nodes. Wireless sensor networks require solution for conserving energy level. One new type of attack called vampire attack, which occurring at network layer. It leads to resource depletion (energy) at each sensor nodes, by destroying battery power of any node. It transmits a small complaint messages to disable a whole network, hence it is very difficult to detect and prevent. Existing protocols are not focusing on this vampire attack happening on routing layer, hence there exist two types of attacks namely, carousel and stretch attack. Hence there is a large of energy loss. New protocol called PLGP, a valuable and secure protocol is proposed along with one-way signature chaining algorithm to avoid this vampire attack. By using this, existing problems can be overcome.
