Abstract: In this work the problem of wormhole attack is identified, and solved it using a multi-path-based approach. This multi-path based AODV approach has been implemented to identify and prevent wormhole attack. We have successfully used this scheme to avoid attacks for MANET environments. And we have presented the analysis of performance with proposed and existing and found that proposed model better than existing approach in terms of PDF and THROUGHPUT, and this is also better. Keywords: Worm Hole Attack, AODV, Multipath AODV, MANET, Performance Matrices.
I. INTRODUCTION In MANET, as the nodes are utilizing open air medium to communicate, they face acute security problems compared to the wired medium. The mobile ad hoc network is vulnerable to various kinds of attacks, among most of the attacks are deployed on the basis of poor routing protocol design. One such critical problem is wormhole attack. During the wormhole attack, a malicious node captures packets from one location in the network, and with the use of tunnels them to another malicious node at a distinct point, which replays them locally. we have identified two types of wormhole attacks. In the first type, malicious nodes do not take part in finding routes, meaning that, legitimate nodes do not know their existence. In the second type, malicious nodes do create route advertisements and legitimate nodes are aware of the Existence of malicious nodes, just do not know they are malicious. Therefore, there is a need to implement security parameters in order to protect MANETs from malicious users. Due to this type of attack creates the path break problem. so, we considered create this type of problem due to wormhole attack. and solved using Multi-Path based AODV approach. In this work, we have presented a simulation-based study of the effects of wormhole attacks in MANETs. In this work we have implement Multi path Based AODV Technique For prevention and detection of wormhole attack. And have compared modified metrics using network simulators version 2 and performance metrics such as PDF and throughput with the existing AODV method. The rest of the paper is organized as follows. In Section 2, we introduce overview of overview of AODV, Section 3 Worm hole attack and Next Sections presents a Problem Statement and solution model multipath methodology to prevent a worm hole attack, result and lastly discussed conclusion.
