This paper presents a mathematical formulation and implementation framework of Fuzzy Logic Controllers in cognitive radio operations. The approach is rooted in fuzzy set theory, enabling linguistic rule-based decision-making for spectrum sensing, power control, and channel selection. In Cognitive Radio Networks, a primary difficulty is determining how Cognitive Radio may utilize a licensed channel without disrupting Primary Users and when to relinquish that channel. In this work, we define a fuzzy logic model that manages the operation of Cognitive Radio to prevent interference with Primary Users. Our proposed model does not just decide the handover according to the Primary Users power but also on the performance of the Secondary User and achievement of quality of service on both Primary Users and Secondary User.
