Abstract: A strategic arrangement of the worm hole can result in an important breakdown in communication across a wireless network. Among of all of these security issues we have considered wormhole attack prevention and detection mechanism in our thesis work. In this thesis, we address the problem of identifying and isolating malicious attack nodes which form wormhole attack. A model is developed for detection and prevention of wormhole, in which have implemented a wormhole detection method based on alternate path. This multi-path technique is based on AODV. And Simulation Analysis show that our implemented approach has good accuracy in terms of PDF and throughput. In simulation have carried out using NS-2 Software. Keywords: Worm Hole Attack, AODV, Multipath AODV, MANET, Performance Matrices.
I. INTRODUCTION MANET is a collection of mobile nodes that have the ability to communicate with each other without a fixed infrastructure. In this each device is free to move freely in any direction. One of the many benefits of MANETs is that it can be used where there is no proper infrastructure support for wireless access and wired backbones. A major drawback of MANET is that since it is an infrastructure less network that is built on the fly, each node here also acts as a router. Due to constant mobility, rapidly changing topology, decentralized controls, it has to face various security concerns.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. Security is one of the biggest challenges of MANET. Safety issues in this are mostly concentrated in the safe passage and the parts that install the data transmission safely. And security has become a major concern in wireless networks and has emerged as an important research area. Which are more vulnerable to intrusion by malicious agents than any wired network. MANETs suffer from a variety of security attacks and threats such as: denial of service, flood attack, impersonation attack, selfish node abuse, routing table overflow attack, wormhole attack, black hole attack. Therefore, we have covered one of the important problems in our work wormhole attack.
