we introduce many types of attack. In many types of attack wormhole attack is more dangerous attack for network because it is very hard to detect. We discussed about a wormhole attack & its models and types. This survey introduces different wormhole detection techniques location based, time based, neighbour information based and authentication based methods using ConSetLoc, Time Petri net, ROCRSSI, LIDeA, Merkle algorithems to detect wormhole attack. And existing detection techniques and its advantages and limitations.
