Abstract:
Recently, a new 802.11aa amendment has been released. Its main goal is to increase quality of service support for audio-video traffic streams. Among others, it defines the intra-access category prioritization mechanism coupled with appropriate traffic selection procedures, in order to increase the granularity of traffic prioritization in comparison to the currently used EDCA. This paper presents the preliminary study of the possible impact of the new feature on quality of experience (QoE) in case of H.264 video streams. The obtained results show that IEEE 802.11aa and 802.1Q parameters should be tuned to efficiently use the available bandwidth.
