Now a day’s mobile customers are will increase tremendously, to finish their necessities with growing channel allocation the Cognitive Cellular Network is crucial to do not forget. CCN be made up a subscribe as mobile and cognitive as unsubscribe person which can be makes use of the mobile band through stopping intervention. The Cuckoo Search Algorithm is taken into consideration to lessen intervention among spectrum allocation for subscriber and unsubscribe customers. CS is cutting-edge nature-stimulated algorithms, that is invited through Yang and Deb [10]. CS do not forget the brood parasitism hobby of a few cuckoo species .Proposed CS is determined greater higher than BCO PSO and ABC , SINR acquired with proposed CS is determined to be higher in comparison to pronounced paintings with Particle Swarm Optimization (PSO), Artificial Bee Colony (ABC) .
