A Survey of Different Techniques for Detection of Wormhole Attack in Wireless Sensor Network

The nature of wireless ad hoc and sensor networks make them very attractive to attackers. One of the most popular and serious attack in wireless ad hoc and sensor network is the wormhole attack. It is a particularly severe attack on routing protocols for ad hoc networks in which two or more colluding attackers record packets at one location, and tunnel them to another location for a replay at that remote location. When this attack targets routing control packets, the nodes that are close to the attackers are defended from any alternative routes with more than one or two hops to the remote location. All routes are thus directed to the wormhole established by the attackers. This paper focuses on Wormhole attack detection in wireless sensor network. The wormhole attack is particularly challenging to deal with since the adversary does not need to compromise any nodes and can use laptops or other wireless devices to send the packets on a low latency channel. In This paper we have discussed and compared some of the very popular techniques for detecting this kind of attack.
