摘　　要：基于分簇结构提出一种适用于AdHoc网络的访问控制方案。通过将资源和节点分等级来实现不同权限的访问控制;采用简单有效的信誉模型和激励机制来改变节点的权限,实现了动态的访问控制;通过簇头代理访问资源,增强了网络的安全性,并且使网络中优质资源得到充分利用。仿真结果表明,该方案有较高的效率和较少的通信量。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 uti- lizes the quality resources. Simulations result show that this scheme is of high efficiency and little communication.
