As many kind of spectrum sensing techniques have been introduced for various wireless technologies. These spectrum sensing models have been improved the spectrum usage and have also opened up new opportunities for the different wireless applications to utilize the radio spectrum more effectively. To exploit these opportunities, the wireless transceivers need to be more intelligent to access the radio spectrum. Such an intelligent wireless transceiver is referred as a \"Cognitive radio\". In this paper the authors proposed efficient cluster based spectrum sensing technique using fuzzy logic controller for Cognitive Radios Network (CRN).
