A SURVEY ON WORMHOLE DETECTION AND PREVENTION APPROACH

Mobile ad hoc network is a dynamic network technology. The topology of network is fully dynamic additionally the centralized control is absent. Since, the network attackers are always trying to break the routing strategy and deploy the attacks. Therefore, the routing protocols are in key role. Among a few different kinds of attack in ad hoc network this paper considers the wormhole attack for investigation. This paper reviews the different techniques utilized for identification of wormhole attack and also suggest a new methodology for avoiding the wormhole attack links
