In an environment where there is no base station and no static infrastructure Mobile Ad Hoc Network plays a vital role. It is becoming popular technology because of fast growth of wireless devices, dynamically changing network topology. Because of the ad hoc in nature MANET is more vulnerable to different types of attacks and thus need to be protected against these attacks. One of the common attacks is infiltration; therefore, infiltrator detection should be added as another defense before an infiltrator can transgression the system. For such defense one can use Infiltrator verification mechanism. In current scenario infiltrator verification mechanism for conventional wireless networks are not well suited for MANETs. In this paper an approach is proposed to implement a new adroit infiltrator verification mechanism which provides second layer security for node isolation attack (DoS) using OLSR. The performance of proposed algorithm is tested in terms of packet delivery ration and network throughput and is found improved as compared to Standard OLSR.
