proposed algorithm for detection and isolation method is described.In Section V an analysis of the results is presented.Finally conclude the paper in section VI. Wormhole AttackIn the wormhole attack, an attacker tunnels messages received in one part of the network over a low latency link and replays them in a different part.The simplest instance of this attack was a single node situated between two other nodes forwarding messages between the two of them as shown in Figure 1.However, wormhole attacks more commonly involve two distant malice nodes colluding to understate their distance from each other by relaying packets along an out-of- AbstractAs 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.Figure 1: Wormhole attack.
