QoE Assessment of Audio-Video Transmission over IEEE 802.11aa GCR with Off-the-Shelf Devices
Teranishi Daiki, Toshiro Nunome · 2018
This paper evaluates the effect of reliable groupcast on Quality of Experience (QoE) of audio-video IP transmission over a wireless LAN with off-the-shelf devices. We utilize IEEE 802.11aa GroupCast with Retries (GCR) Unsolicited Retry as a reliable groupcast scheme. We think that a wireless access point groupcasts audio and video streams to several terminals connected to the access point. We use GCR Unsolicited Retry as a transmission method of audio-video data and evaluate application-level Quality of Service (QoS) on several experimental conditions. In addition, we assess QoE by a subjective experiment. As a result, we find that GCR Unsolicited Retry presents higher QoE than a conventional transmission method.
