dc.descriptionTele-education went from being an option to becoming a necessity given the current public health problems. Due to this, the educational sector has included blended courses as part of its training offer. Mobile Ad Hoc Networks (MANETs) will therefore, become an important resource to work, under this class format, with students outside the classroom, in accordance with the standards recommended inside a university campus. MANETs require certain parameters that ensure the quality of communications and identify the factors that influence Quality of Service (QoS). The purpose of this study is to determine the factors that affect the quality of communications in a tele-education environment. For this purpose, the QoS of a MANET supporting a real-time video streaming is evaluated based on throughput. As a result, the main factors that directly or indirectly affect the operation of the network could be identified, which may help in making decisions regarding aspects such as the number of nodes and the node mobility speed. Moreover, the versatility and scalability of the MANET was proven, as when the number of nodes went from 5 to 10, throughput increased by 14 %. This also occurred with the transmission rate factor when the video was streamed in a channel with a variable bitrate (64–4096 kbps).en-US
dc.descriptionHoy en día, la teleeducación pasó de ser una opción a una necesidad provocada por problemas de salud pública. Por ello, el sector educativo ha adoptado, como parte de su oferta formativa, el formato de cursos semipresenciales. Por tanto, la red móvil ad hoc network (MANET) debe ser un recurso importante para trabajar bajo este formato con estudiantes fuera del aula según las normas recomendadas dentro del campus universitario. Esta red requiere parámetros que aseguren la calidad de la comunicación e identifiquen los factores que inciden en la calidad del servicio (QoS). Este trabajo tiene como objetivo determinar los factores que afectan la calidad de la comunicación en un entorno educativo mediante la evaluación de la QoS de la red a través del parámetro throughput con la transmisión de un servicio de teleeducación en tiempo real como el video streaming soportado en una MANET. Como resultado se pudo identificar los principales factores que afectan de forma directa o indirecta el funcionamiento de la red para poder tomar decisiones con respecto al número de nodos y a la velocidad de movilidad de estos, entre otros. De esta forma, fue posible demostrar la versatilidad y escalabilidad de la MANET que, al aumentar la red de 5 a 10 nodos, incremento el throughput en un 14 %. Igualmente sucedió con el factor de tasa de transmisión con la emisión de un video compartiendo un canal con una velocidad de bits variable de 64 – 4096 kbps.  es-ES
