Abstract: This paper proposes an access control scheme for cluster-based Ad Hoc networks. This scheme classifies the resources and nodes into levels to provide differentiated privileges access control. A dynamic access control mechanism is implemented based on the simple effective trust model and incentive mechanism which can change the node’s privilege. The cluster-head proxy is developed to access the resource that enhances security and fully utilizes the quality resources. Simulations result show that this scheme is of high efficiency and little communication.
