Wireless Mesh Networks (WMNs) are believed to revolutionize wireless internet connectivity by economically extending broadband internet access over very large areas. In their default state, WMNs operate in the ISM band. Due to severe congestion in this unlicensed band, some of the constituent Mesh Routers (MRs) in a WMN may have over-congested operating conditions. Hence, it is desirable for such MRs to operate on a different band. There exist unused or white spaces in the spectrum used by licensed operators, who are referred to as Primary Users (PUs). Cognitive radio technology is one that...

"Spectrum Selection, Sensing, and Sharing in Cognitive Radio Networks" introduces the readers to a comprehensive idea about the evolution and functionality of Cognitive Radio from a network perspective. The book covers an efficient modeling technique of spectrum occupancy patterns of primary users in licensed bands, substantiating the results based on real-time experiments performed in Boston, MA, USA. The next chapter introduces a new idea for cognitive radio termed as "Spectrum Selection," a concept of preferable selection of spectrum for further spectrum sensing. A separate chapter on...
