In MANET is a collection of autonomous system of mobile nodes connected with each other using wireless link and each node communicates with each other using wireless link that are within its transmission range. The network is unbounded by any fixed infrastructure or any central authority. The dynamic topology and open nature makes the Mobile Ad-hoc NETwork (MANET) more vulnerable to security threats. The success rate of MANET highly depends on the confidence in the security shown by the users. Wormhole attack is one such security threat at network layer which causes routing disruption.
