    摘要: In communication networks, a cognitive network (CN) is a
    new type of data network which is used to solve some of the problems
    that face current networks. Cognitive radio (CR) is part of a cognitive
    network and a smart wireless communication system. CR is conscious
    of its surrounding environment, and learns from the environment. It
    adapts its internal states by making corresponding real-time changes in
    certain operating parameters. In this paper, we propose a novel
    Cognitive RBAC (Role-Based Access Control) scheme which can be
    applied to Mobile Heterogeneous Networks (MHNs). The MHNs consist
    of mobile communication systems and Wi-Fi systems. The required new
    definitions for the RBAC model are proposed in this paper. They can
    improve the ability of conventional RBAC model to meet new
    challenges. In our scheme, we assume that a Cognitive Server (CS)
    provides and manages the permissions of services, and Network
    Providers support and manage a variety CRs and CNs, individually. For
    more efficiently managing CR and CN and meeting the large scale
    heterogeneous networks, we let mobile user can perceive network
    candidate actively to access services, in which the permissions are
    depending to the contract made by CS with each Network Provider. In
    this paper, the new generalized cognitive RBAC model and their
    definitions are proposed, and could be applied to new applications in a
    MHNs environment.
