A Critical Study on Wormhole Detection and Prevention In Manet |
A Mobile Ad hoc Network (MANET) is acollection of self-configurable mobile node connected through wireless links.Absence of central controller it is difficult to determine the reliable &secure communication in Mobile Ad hoc network. Worm hole attack that are workas to established path in between sender and receiver but if the sender hasstart data transmission then in that case the worm hole attacker has create adirect link, referred to as a wormhole tunnel between them, it means more ofthe number of trusted nodes it means higher successful data communicationprocess rates may well expected. In this desertion we proposed detection aswell as prevention technique against wormhole attack, for detection we useprofile base detection technique and get attacker node information like nodenumber, number of attack packet, attack time etc. after that we preventwormhole attack using neighbor trust worthy base technique and secure themobile ad-hoc network communication, through our proposal we provide secure aswell as reliable communication and simulate through network simulator-2 andanalyze the network behavior in attack and prevention case.
