Dynamic Spectrum Management Policy for Cognitive Radio: An Analysis of Implementation Feasibility Issues
Junseok Hwang, Hyenyoung Yoon · 2008
Recently, a dynamic spectrum access technology has been in the spotlight for maximizing the utilization of the limited radio spectrum resource while accommodating the increasing amount of services and applications in the wireless networks. A cognitive radio is one of the key technologies based on dynamic spectrum manner. Although there have been many advances in cognitive radio with respect to the technology development, an additional research for the reformation of regulation, policy and market structure is still required to make CR-based dynamic spectrum access feasible and successful in the wireless market. Therefore, this paper classifies cognitive radio based network and application scenarios, and investigates feasibility of them. According to the analyses, this paper examines strategic approaches in the service providers', manufacturers', and policy makers' standpoints for the successful commercialization of cognitive radio with the dynamic spectrum management policy.
