Mobile Ad hoc NETwork (MANET) is a collection of mobile nodes without any centralized administration. It is easy to deploy malicious node to impersonate another node in MANET. Mobile ad hoc network has no clear line of defense, so, it is accessible to both legitimate network users and malicious nodes. In this paper, trust oriented reputation system is developed which attains trust convergence and authentication to the mobile nodes. In the first phase of the scheme, detection of the malicious node is achieved.
