摘要：The current demand of MANET is its security and robustness. MANET’s operational performance also depends on security. An attacker can easily attack on MANET because of its open nature and bandwidth constraint. Most of research have been done on the MANET security. Wormhole attack is most severe threat to security of MANET. In which two faraway malicious nodes are linked to each other with high speed link called wormhole tunnel. Most of previous research work done on detection and prevention of wormhole attacks uses packet leashes, extra hardware (GPS, Directional Antenna etc.) and few modifies the source code of routing protocols to improve security. In this paper, we propose a security model that will detect and avoid the wormhole attack in MANET using routing protocol i.e., AODV protocol. Proposed security model has three phases. In the first phase, detection of malicious node is done by using Bogus RREQ and in second phase normal AODV operation is performed for detection of shortest path from source to destination. In the third phase, once again detection of attacker is done by using delay metric if there is presences of wormhole attack then it repeats from phase one otherwise selects the shortest route to destination discovered in phase second.
