Wormhole attack is a Routing-Disruption Attack in ad hoc networks, those malicious nodes in these networks can bear wormhole attacks to make up a false scenario on neighbor discovery relations among mobile nodes. The attackers endanger the safety of ad hoc routing protocols with making a direct link, referred to as a wormhole tunnel, between malicious nodes. After building a wormhole tunnel, one attacker receives and copies packets from its neighbors, and forwards them to the other colluding attacker through the wormhole tunnel. However they need special hardware to support such communication.This article reviews wormhole attack on ad hoc networks and discusses approaches for preventing wormhole attack in these networks.
