As an increasing number of people are going wireless, reducing the criticism of wireless networks is becoming a top priority. Wormhole attack is a severe threat against ubiquitous sensor networks. In a wormhole attack, the intruder sniffs the packets at one point in the network and forwards them with a less latency and relays them to another point in the network. A strategic placement of the wormhole can result in a significant breakdown in communication across a wireless network. The objective of dissertation addresses the efficient comparing the proposed technique with the previous study. In this paper, we have proposed an algorithm where intrusion detection has been done in a proposed approach to detect the wormhole attacks. The AODV routing protocol is used as the underlying network topology. Data tracker is used for detecting and isolating the malice node i.e. acting as a wormhole. This approach is implemented by using NS-2. The Simulation results are presented to validate the stated goal by comparing various performance metrics.
