چکیده
Due to the rapid increased in the day by day users for spectrum cause scarcity of it. So due to its limitation and for the effective utilization of spectrum Cognitive Radio (CR) technology came into existence. This CR consists of its four main modules, which are: Spectrum sensing, mobility, sharing and management. Among which spectrum sensing is the keystone part, as due to the dependency of other parts on it. For this many evolutionary algorithms are applied, so may that an optimized result may be obtained. This paper focuses on the optimization problem of spectrum sensing in cognitive radios. The algorithms which are used as genetic, particle swarm, ant colony, simulated annealing, flower pollination, cuckoo search and so more, also they are directly related to the natures, among which FPA (Flower Pollination Algorithm) is one of these. This FPA has compelling qualities. This is somehow related to the pollination process of flowers. Due to its good convergence rate, is used for spectrum sensing.
