Redes inalámbricas definidas por software, calidad de servicio en sistemas IoT, soporte de comunicación, gestión del tráfico de mensajesResumen
Varios sistemas IoT demandan comunicación en tiempo real, lo que introduce restricciones temporales en la transmisión de datos y ejerce presión sobre la propagación de los mensajes en la red. Muchos de estos sistemas deben abordar estos requerimientos de comunicación considerando el uso de redes inalámbricas, lo que aún representa un problema abierto. Para afrontar este escenario de comunicación, es fundamental emplear estrategias de configuración dinámica que puedan adaptarse rápidamente al comportamiento de la red, garantizando la estabilidad y previniendo fallas bajo determinadas condiciones operativas. Por lo tanto, resulta necesario recurrir a mecanismos para implementar redes definidas por software (SDN), considerando la comunicación inalámbrica en tiempo real, a fin de dar soporte a estas aplicaciones. Este trabajo se basa en investigaciones previas de los autores y muestra cómo implementar redes definidas por software que se adapten dinámicamente a los requerimientos de tráfico en tiempo real en una red inalámbrica. El modelo de red fue implementado y evaluado utilizando el simulador NS-3. Los resultados experimentales demuestran que la incorporación de políticas SDN en redes inalámbricas mejora la predictibilidad de estos sistemas. Las bibliotecas implementadas en NS-3 fueron publicadas y puestas a disposición de investigadores y desarrolladores, quienes pueden utilizarlas para modelar y evaluar redes inalámbricas definidas por software específicas.
