Abstract

A wireless sensor networks is a temporary, infrastructure less network where nodes communicate without any centralized mechanism. This dynamic behaviour of WSN makes this network more potentially applicable in conference, battlefield environment and disaster relief, and has received significant attention in recent years. Attacker may use this weakness to disrupt the network. Subsequently, Power draining is the major thread; where attacker not only exhausts the network traffic but also degrades the life of node as well network. The objective of this study is to detect and prevent wireless sensor networks from unwanted power draining due to Vampire attack. Here, Targeted Flooding through high battery capacity node has been used to deploy Vampire attack in mobile ad-hoc network. Subsequently, energy consumption and capacity observation technique has been used to detect malicious node(s). Furthermore, prevention method forcefully shutdown malicious nodes and transfer communication.
