Resumen (es_ES)

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. El objetivo de este artículo es analizar y comparar el desempeño de dos algoritmos de toma de decisiones multicriterio: Topsis y Vikor, con diferentes niveles de colaboración entre usuarios secundarios. Los dos algoritmos se evalúan y comparar con respecto al retardo durante una transmisión de información de 9 MB. La comparación se realizó bajo cuatro escenarios distintos, de acuerdo con la clase de servicio y el nivel de tráfico, para la banda de frecuencia GSM. De acuerdo con los resultados alcanzados el algoritmo Topsis tiene un mejor desempeño en los diferentes escenarios y niveles de colaboración.

Resumen (en_US)

Cognitive radio is a technology that makes efficient use of the spectrum allowing secondary users to use the spectral opportunities of the licensed bands, but without interfering with the communications of the primary users. The objective of this article is to analyze and compare the performance of two multicriteria decision making algorithms: Topsis and Vikor, with different levels of collaboration between secondary users. The two algorithms are evaluated and compared at the delay level during an information transmission of 9 MB. The comparison is made under four different scenarios, according to the class of service and the level of traffic, for the GSM frequency band. According to the results achieved, the Topsis algorithm has a better performance in different scenarios and collaboration levels.
