Security is not guaranteed in wireless ad hoc network because of its unstable infrastructure. This network suffers from various attacks; here in this paper, the authors deal with wormhole attack. Wormhole is identified base on the fact that transmission time between two fake neighbors created by wormhole is considerably higher than that between two real neighbors which are within radio range of each other. Many techniques are used to detect wormhole attack but they do not efficiently remove the wormhole.
