Análisis de la Movilidad Espectral en Redes de Radio Cognitiva

Abstract: Se presenta una revisión sobre la movilidad espectral en redes de radio cognitiva, describiendo el Handoff espectral, sus clasificaciones, sus enfoques actuales, sus criterios de decisión y sus métricas de evaluación de acuerdo con la literatura actual. La revisión se realizó a partir del análisis de publicaciones recientes de corriente principal con sus respectivas citas, tratando de proveer un marco referencial completo de la literatura actual sobre la movilidad espectral en redes de radio cognitiva.

“…The International Telecommunications Union (ITU) defines cognitive radio (CR) as a "radio or system that detects and is aware of its surroundings and can be adjusted dynamically and autonomously according to its radio operation parameters" (Hernández, Pedraza, Páez, & Rodriguez-Colina, 2015). The solution in cognitive radio against the inefficient use of the radioelectric spectrum is none other than the dynamic access to the spectrum (DSA), allowing the opportunistic use of the available frequencies by secondary users (SU) without causing any interference to the primary users (PU) (Hernández, Pedraza, et al, 2015;R. López & Montejo Sánchez, 2015).…”

“…Hay varios estudios y publicaciones en el área de radio cognitiva, como se muestra en Wang y Ray Liu (2011) y Ghosh, Das y Chatterjee (2014); sin embargo, la mayoría de ellos se ha enfocado en proponer y validar algoritmos para el acceso al espectro en ambientes de un solo usuario, lo cual se aleja un poco de la realidad al no considerar un acceso multiusuario (Shetty, Agbedanu y Ramachandran, 2011;Carrillo,Mathilde, Yoshimura y Bazzo, 2013;Casadevall y Perejil, 2016;Hernández, Pedraza, Páez y Rodríguez, 2015;Ordoñez, 2016). Uno de los pocos trabajos que presenta un análisis multiusuario para redes de radio cognitiva es el de Liu, Nasser y Hassanein (2013), en el que se evalúa el rendimiento de dos algoritmos de asignación espectral en redes multiusuario: algoritmo genético y algoritmo heurístico.…”

“…The trending growth of applications, the scarcity of the radio electric spectrum and its underuse are current problems of wireless networks, which have fostered the use of strategies for dynamic and optimal access of the spectrum [1]- [4]. Cognitive radio (CR) is a promising approach that includes efficient and adaptive methodologies for the dynamic spectrum allocation (DSA) of existing radio [2], [5], [6].…”
