MANET has no clear line of defense, so, it is accessible to both legitimate users and malicious attackers. Availability of network services, confidentiality and integrity of the data can be achieved by assuring that security issues have been met. In this paper, the authors develop a security based technique using some routing protocols so as to recognize & eradicate the problem of gray hole attack in mobile adhoc network. In first phase, they develop the method to handle the spiteful node in the network. In the next phase of protocol is to implement the gray hole attack so as to recognize gray hole attack & find out its consequences on the adhoc network.
