Wormhole Attack Detection and Prevention in Mobile Ad-hoc Network Using Authentication Based Delphi

As Mobile Ad-hoc network is infrastructure less network in which every node can take part in data transmission and reception process. Various kinds of attacks have been arises in the network during transmission, which affects on the performance of the network. Wormhole attack is one attack from them which is created by collaborative attackers. Different techniques have developed to detect & prevent wormhole. But perfect solution is yet to be covered. Delay per Hop Indication (DelPHI) is a technique for wormhole detection in which authentication is essential in order to provide prevention. This is an effective approach to detect the fake route and also adopt preventive measure against wormhole nodes so that it will not appear in the route discovery phase. The focus of this paper is to provide a better solution in terms of wormhole detection of wormhole and to take some preventive measurement against the wormhole by considering the pros and cons.
