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.
