Cet article évalue la qualité de service et la qualité d'expérience (QoE) au niveau de l'application dans le cas où les flux audio et vidéo sont transférés avec l'accès amélioré aux canaux distribués (EDCA) du MAC IEEE 802.11e. Dans EDCA, une station peut transmettre plusieurs trames MAC pendant une opportunité de transmission (TXOP) ; c'est ce qu'on appelle l'éclatement TXOP. Par simulation, nous comparons d'abord la QoS au niveau de l'application avec le schéma d'éclatement TXOP et celui sans le schéma pour différentes distances entre le point d'accès (AP) et les stations. Dans cet article, nous supposons que le taux d’erreur sur les bits (BER) augmente à mesure que la distance augmente. Les résultats numériques montrent que le TXOP-bursting peut améliorer de nombreux paramètres de qualité vidéo tels que le délai moyen des unités multimédias (MU), le taux de perte MU et la qualité de synchronisation multimédia, en particulier lorsque le point d'accès envoie des flux audio et vidéo aux stations dans le sens de la liaison descendante. Nous examinons ensuite l'effet de TXOPlimite sur la qualité vidéo. Les résultats de simulation montrent que la qualité vidéo peut être dégradée si la valeur de TXOPlimite c'est trop petit. De plus, nous évaluons la QoE par la méthode des catégories successives, qui est une méthode psychométrique. Les résultats numériques montrent que le TXOP-bursting peut également améliorer la QoE. Nous effectuons également un mappage QoS entre le niveau application et le niveau utilisateur avec une analyse des composants principaux et une analyse de régression multiple.

Abstract: This paper assesses application-level QoS and Quality of Experience (QoE) in the case where audio and video streams are transferred with the enhanced distributed channel access (EDCA) of the IEEE 802.11e MAC. In EDCA, a station can transmit multiple MAC frames during a transmission opportunity (TXOP); this is referred to as TXOP-bursting. By simulation, we first compare application-level QoS with the TXOP-bursting scheme and that without the scheme for various distances between access point (AP) and stations. In this paper, we suppose that the bit error rate (BER) becomes larger as the distance increases. Numerical results show that TXOP-bursting can improve many metrics of video quality such as average media unit (MU) delay, MU loss ratio, and media synchronization quality, particularly when the AP sends audio and video streams to stations in the downlink direction. We then examine the effect of TXOPLimit on the video quality. Simulation results show that the video quality can be degraded if the value of TXOPLimit is too small. Furthermore, we assess QoE by the method of successive categories, which is a psychometric method. Numerical results show that TXOP-bursting can also improve the QoE. We also perform QoS mapping between application-level and user-level with principal component analysis and multiple regression analysis.
