Title
A novel IEEE 802.11aa intra-AC prioritization method for video transmissions
Abstract
Ensuring QoS guarantees for real-time multimedia traffic in WLANs has recently attracted a lot of attention from standardization bodies and researchers. In order to increase the granularity of traffic prioritization and QoS support provided by EDCA, the intra-access category prioritization mechanism has been proposed in the recent IEEE 802.11aa amendment. In order to improve real time transmission over WLANs, two standard transmission selection algorithms can be used to prioritize traffic within the voice and video access categories of EDCA: the strict priority algorithm and the credit-based shaper algorithm (CBSA). This paper focuses on the improvement of video transmission over WLANs using two video transmission queues (primary and alternate) and the two traffic selection algorithms and compares the behavior of IEEE 802.11aa with legacy EDCA. Additionally, it comments on the possible ways of CBSA implementations. Finally, it proposes an adjustment of CBSA to wireless environment (WCBSA) which gives the most promising results.
