La radio cognitiva es una tecnología que hace un uso eficiente del espectro y permite a los usuarios secundarios utilizar las oportunidades espectrales de las bandas licenciadas, pero sin interferir con las comunicaciones de los usuarios primarios.

Cognitive radio networks (CRN) allow for an increase in spectral efficiency and performance of today's wireless networks. Currently, multiple proposals exist in the area of spectral decision-making and mobility; however, very few evaluate the impact

A very important task in Mobile Cognitive Radio Networks (MCRN) is to ensure that the system releases a given frequency when a Primary User (PU) is present, by maintaining the principle to not interfere with its activity within a cognitive radio syst

Spectrum sensing is one of the most important processes in Mobile Cognitive Radio Networks because the whole system depends on its values to decide on the spectrum frequency assignment to the secondary users. The mobility of all the users in these ne
