dc.descriptionEl handoff espectral, en las redes de radio cognitiva, ocurre cuando el usuario secundario debe dejar el canal de frecuencia que está utilizando y continuar su comunicación en otra oportunidad espectral. Este proceso es un aspecto clave para garantizar una adecuada calidad de servicio y mejorar el desempeño en las comunicaciones del usuario secundario. Este libro de investigación tiene por objetivo presentar una propuesta de modelo adaptativo multivariable de handoff espectral para redes móviles de radio cognitiva. Para lo anterior, se desarrollaron tres algoritmos para la toma de decisiones durante un handoff espectral, con diferentes enfoques: difuso, realimentado y predictivo; estos conforman el modelo adaptativo multivariable de handoff espectral propuesto. Para evaluar el nivel de desempeño de los algoritmos desarrollados se realizó un análisis comparativo entre estos y los algoritmos de handoff espectral más relevantes en la literatura actual. A diferencia de los trabajos relacionados, la evaluación comparativa se validó a través de una traza de datos reales de ocupación espectral capturados en la banda de frecuencia GSM y Wi-Fi, que modelan el comportamiento real de los usuarios primarios. En la fase de validación, se propusieron ocho escenarios de evaluación, al considerar, dos tipos de redes: GSM y Wi-Fi, dos clases de aplicaciones: tiempo-real y mejor-esfuerzo, dos niveles de tráfico: alto y bajo, y diez métricas de evaluación.spa
dc.description.abstractSpectral handoff, in cognitive radio networks, occurs when the secondary user must leave the frequency channel they are using and continue their communication at another spectral opportunity. This process is a key aspect to guarantee adequate quality of service and improve performance in secondary user communications. This research book aims to present a proposal for a multivariate adaptive spectral handoff model for mobile cognitive radio networks. For this purpose, three algorithms were developed for decision-making during a spectral handoff, with different approaches: fuzzy, feedback and predictive; These make up the proposed adaptive multivariate spectral handoff model. To evaluate the level of performance of the developed algorithms, a comparative analysis was carried out between them and the most relevant spectral handoff algorithms in current literature. Unlike related works, the benchmark was validated through a trace of real spectral occupancy data captured in the GSM and Wi-Fi frequency band, which models the real behavior of primary users. In the validation phase, eight evaluation scenarios were proposed, considering two types of networks: GSM and Wi-Fi, two classes of applications: real-time and best-effort, two traffic levels: high and low, and ten evaluation metrics.spa
