Abstract: Abstract-Preliminary studies and general observations indicate a significant amount of "white space" in radio spectrum, varying in frequency, time, and geographic locations. Enabled by regulatory initiatives and radio technologies advances, opportunistic usage of the white space can potentially mitigate the spectrum scarcity. In this paper, we consider a scenario in which secondary users can opportunistically access unused spectrum vacated by idle primaries. In such a spectrum-agile system, a critical and uniq… Show more
