Abstract

Current wireless networks feature fixed spectrum assignment policies, according to which licensees are granted the rights for the use of frequency bands on a long-term basis over vast geographical regions. Moreover, the huge success of wireless applications has prompted the exponential growth of unlicensed band usage, thus causing possible wireless spectrum shortage. Part of the problem is that spectrum usage is not uniform (according to FCC, only 15 to 85 percent of the licensed spectrum is utilized on average). © 2009 IEEE.
