Abstract
Este trabajo presenta un sistema de transmisión inalámbrica multimedia coordinada basado en DASH-SAND (Server and Network Assisted DASH). La solución aprovecha el protocolo SAND para intercambiar información de red entre el servidor y los clientes, mejorando la adaptación del streaming de vídeo DASH en entornos inalámbricos con múltiples usuarios concurrentes. Se presentan resultados experimentales que demuestran las ventajas de la coordinación asistida por red para mejorar la Calidad de Experiencia (QoE) en escenarios inalámbricos.
