The ISM frequency bands (902~918 MHz (region 2 only), 2.4 GHz ~ 2.483 GHz, and 5.725~5.875 GHz) are unlicensed bands available for use by commercial technologies. In particular, the 2.4 GHz ~ 2.483 GHz band is very popular and is currently used by WiFi, Zigbee, Bluetooth, and RFID technologies. Moreover, microwave ovens, hand held phones, and other wireless devices operate in the same frequency range,...
Protocols in Cognitive Radio Networks (CRNs) tune the radio and network parameters to utilize the unused frequency spectrum, and thus improve the application performance. Generalized Network Utility Maximization (GNUM) approach has been used to derive optimal algorithms in CRN from a theoretical formulation of the problem. However, there are several practical challenges for realizing these algorithms...
