It generally works by broadcasting the information and used air as medium. It's broadcasting nature and transmission medium also help attacker, whose intention is to spy or disrupt the network. Many type of attack can be done on such Mobile Ad-hoc network. The emphasis of this paper to study wormhole attack, some detection methods and different techniques to prevent network from these attacks.
