The cognitive radio networks are an alternative to mitigate the saturation of the radio spectrum in some frequency bands, through a dynamic spectral assignment, where the secondary user opportunistically takes advantage of the free frequency channels of the licensed band of the primary user. In the present article an algorithm is developed to select free frequency channels or spectral opportunities in a cognitive radio network, based on the Artificial Bee Colony method. The evaluation of the proposed algorithm is carried out through simulations that incorporate the real behavior of the primary user, using real spectral occupancy traces, obtained through the spectrum monitoring with the energy detection technique, and having as evaluation cr...
