System Info of Multi-Domain Cognition in Cognitive Radio Networks
The environment cognition of cognitive radio networks (CRN) is extending from wireless domain (WD) to network domain (ND), user domain (UD) and policy domain (PD). In this paper, we propose three-layer system info of multi-domain cognition (MDC) with the characteristic of policy restriction and the capability of learning and reasoning. Especially, multidomain local cognition (MDLC) layer performs the acquirement of mass multi-domain cognition information (CI). Integrative consideration of effective expression, efficient transfer and distributive processing, multi-domain cooperative cognition (MDCC) layer implements rational flow and fusion of CI and multi-domain initiative cognition (MDIC) layer effectively utilizes CI by prediction and reasoning. After interpreting the connotation of MDC, we also present cognition framework in space and the simple mathematic model of MDC. In addition, we present the research challenges ahead as well.
