Researching on future spectrum management based on cognitive radio

The influence of cognitive radio to future spectrum management was discussed through the aspects of management. And this paper has discussed the goals and purpose of the future spectrum management and announced that the future spectrum management function will be placed on the cognitive radio nodes. We give the point that the independence between policies and behaviors, behaviors and protocols can improve the mobility of spectrum management and brings the flexibility. And architecture of the future spectrum management involved a spectrum database and a policy database has been proposed. Also, a proposed layering framework of future spectrum management was presented, and the relative management processing is demonstrated too.
