In present era, where every person has become addicted to wireless networks, MANET'S has fulfilled the demand of the people by removing the dependency of fixed network.Mobile ad-hoc networks have extended the range of mobile nodes beyond their level.Now when we talk about wireless communication, routing is the backbone of any communication.Ad hoc on demand multipath distance vector routing algorithm (AOMDV) is a very reactive protocol in MANET's.We have selected AOMDV algorithm for routing purpose as there have already been done several work with AODV.Also, in AOMDV the end to end delay is reduced by utilising several parallel paths.Various routing attacks have been identified in single path routing but here we have introduced worm hole attack in multi path routing i.e.AOMDV routing algorithm.In this paper, we have studied the performance of AOMDV algorithm under worm hole attack.Also, we have provided security and authentication to each and every node by the use of public key and private key.Different metrics of the proposed protocol has been evaluated from simulation on NS2 on different scenarios i.e. with worm hole attack and without worm hole attack and there has been a noticeable improvement in the throughput and energy consumption is also reduced.
