Detection and Prevention of Wormhole Attack Using Decentralized Mechanism
Akanksha Gupta · 2014
Wireless networks are susceptible to many attacks, including an attack known as the wormhole attack. A wormhole is one of prominent attack that is formed by malicious colluding nodes. This attack can results in a serious danger in computer networks, particularly against a lot of location-based wireless security systems and ad hoc network routing protocols. The wormhole is feasible still when the attacker has not cooperated as any hosts. A planned position of the wormhole can consequence in a momentous collapse in communication across a wireless sensor network. A planned position of the wormhole can consequence in a momentous collapse in communication across a wireless sensor network. In these attacks two or more wicked colluding nodes generate a high-level effective tunnel in the network, which is engaged to carry packets between the tunnel endpoints. These tunnels imitate shorter links in the network and so perform as benefit to unsuspicious network nodes which by default look for shorter routes. The detection and prevention of such wormholes in an ad-hoc network is still considered a challenging task. Numerous approaches have been proposed for the detection and isolation of wormhole nodes. In this paper we have proposed a new approach for detection and prevention of Wormhole attack. The proposed approach is an improvement over the existing technique and the simulation results of proposed technique show better performance in comparison to the existing technique.
