LOPEZ SARMIENTO, Danilo Alfonso; RIVAS TRUJILLO, Edwin  and  GUALDRON GUERRERO, Oscar Eduardo. Proposed methodology for assignment of spectral bands in wireless cognitive radio networks. Tecnura [online]. 2014, vol.18, n.spe, pp.61-69. ISSN 0123-921X.  https://doi.org/10.14483/udistrital.jour.tecnura.2014.DSE1.a05.

This paper raises a proposal starting from the current state that improves the process of allocation of spectral bands at the decision-making stage in cognitive radio, decreasing the time that the system takes to select a channel to transmit data from unlicensed users, assuming the existence of free spectrum and estimating the behavior of the secondary user and primary user.

Keywords : Cognitive radio networks; licensed and non-licensed users; proposal within conceptual diagram framework; spectral decision-making.
