Cognitive radio network management

The regulatory agencies have been pushed by the increasing demand for wireless ubiquitous connectivity to be ever more aggressive in providing innovative ways to use spectra efficiently. Driven by these new opportunities, the future radio systems should look for the optimized architecture, circuit, and algorithm as a whole. In this article, it has been investigated both the unique merits and the challenging tasks of combining policy-based management philosophy with cognitive radio technologies. Some example analysis have also been discussed. It is highly expected that the appropriate combination of policy-based management and CR will lead future wireless communications.
