ABSTRACT
 

In multi hop wireless adhoc networks, there is a need for cooperation between nodes to route each other’s packets. This exposes these nodes to a wide range of security attacks. Also due to the vulnerability of the routing protocols, the wireless adhoc networks face several security risks. A particularly severe security attack that affects the adhoc network routing protocols, is known as the wormhole attack. The wormhole attack is carried out as a two phase process launched by one or more than one malicious nodes. In the first phase, these malicious nodes, called as wormhole nodes, try to lure legitimate nodes to send data via them by participating in the network. In the second phase, wormhole nodes could exploit the data & affect the communication by misbehaving.
