Mobile ad hoc Network (MANET) is more commonly outlined as a network containing workforce of self-sustaining nodes interconnected with the aid of wireless connections.Considering that the entire mobile nodes in MANET can transfer freely, every node can behave as a router to forward packets from source to destination.So routing security needs to be relevant in MANET which results in performance degradation.The Denial of service (DoS) attack has more force in MANET that intents several forms of severalattacks in the ad hoc network.In order to beat the DoS attack we advocate a new methodology that is best suitablefor Optimized link State Routing (OLSR) protocol.The new mitigation system is to shield the OLSR protocol from node isolation attack.Securing information under such circumstances becomes an important consideration.In Elliptic Curve Cryptography (ECC), large size keys are required and secret sharing among neighbors should be initiated repeatedly because of the mobility of nodes.Therefore, an efficient key management scheme which overcomes the above drawbacks is still a prime requirement in MANETs.
