Recently, we have witnessed a flurry of research activities in search of dynamic spectrum access (DSA) strategies for improved efficiency. This research is multi-disciplinary and spans the engineering, economics and regulatory communities. Ideas of cognitive radio (CR) are also integral to much of this research. DARPA was one of the early proponents of such research under its XG program. XG sought to develop spectrum management policies and technologies for DSA, based on the notions of real-time, low-power, wideband sensing, rapid channel characterization, and opportunity determination by a policy reasoner. XG concepts are being incorporated in subsequent DARPA programs such as WNAN and WAND. NSF recently launched the Programmable Wireless Networks (ProWiN) program to address basic issues in spectrum agile radios and networks. Research in Europe has been supported under the Research Frame-work and the DRiVE program. Standardization efforts are underway under the IEEE 802.22 umbrella. Regulatory agencies in the U.S. (e.g., the FCC), the European Union, and elsewhere are in the process of redefining spectrum policies. There have also been several conferences and workshops devoted to DSA and CR (e.g., DySpan, CrownCom, IEEE Workshop on Cognitive Radio Networks).
