“…The Dynamic TXOP (D-TXOP) scheduling algorithm [80] analyzes the video of the prerecorded streams before the call setup, which has been previously highlighted in [84]. The D-TXOP is suitable for transmitting type (I) of VBR video source categorized in Subsection III-A, which shows variability in packet size.…”

Recently, the demand for multimedia applications is dramatically increased, which in turn increases the portion of video traffic on the Internet. The video streams, which require stringent Quality of Service (QoS), are expected to occupy more than two-thirds of web traffic by 2019. IEEE802.11e has introduced HCF Controlled Channel Access (HCCA) to provide QoS for delay-sensitive applications including highly compressed video streams. However, IEEE802.11e performance is hindered by the dynamic nature of Variable Bit Rate (VBR) video streams in which packet size and interval time are rapidly fluctuating during the traffic lifetime. In order to make IEEE802.11e able to accommodate with the irregularity of VBR video traffic, many approaches have been used in the literature. In this article, we highlight and discuss the QoS challenges in IEEE802.11e. Then, we classify the existing QoS approaches in IEEE802.11e and we also discuss the selection of recent promising and interesting enhancements of HCCA. Eventually, a set of open research issues and potential future directions is presented.

“…Figures 10 and ? ? show both simulation; and analytical results for the HCCA, AXTOP scheduling schemes were computed using Equation (18) and AMTXOP in Equations (22). The simulation and analytical results reveal that the model and the simulation agree for both video sequences with acceptable difference up to maximum 10% which caused by the disregarded overheads.…”

Adaptive multi-polling scheduler for QoS support of video transmission in IEEE 802.11e WLANs

et al. 2015

The 802.11E Task Group has been established to enhance Quality of Service (QoS) provision for time-bounded services in the current IEEE 802.11 Medium Access Control (MAC) protocol. The QoS is introduced throughout Hybrid Coordination Function Controlled Channel Access (HCCA) for the rigorous QoS provision. In HCCA, the station is allocated a fixed Transmission Opportunity (TXOP) based on its TSPEC parameters so that it is efficient for Constant Bit Rate streams. However, as the profile of Variable Bit Rate (VBR) traffics is inconstant, they are liable to experience a higher delay especially in bursty traffic case. In this paper, we present a dynamic TXOP assignment algorithm called Adaptive Multi-polling TXOP scheduling algorithm (AMTXOP) for supporting the video traffics transmission over IEEE 802.11e wireless networks. This scheme invests a piggybacked information about the size of the subsequent video frames of the uplink streams to assist the Hybrid Coordinator accurately assign the TXOP according to actual change in the traffic profile. The proposed scheduler is powered by integrating multi-polling scheme to further reduce the delay and polling overhead. Extensive simulation experiments have been carried out to show the efficiency of the AMTXOP over the existing schemes in terms of the packet delay and the channel utilization.

“…Therefore video source can cooperate with the packet switching devices to provide the valuable frame size information. Feed-forward bandwidth indication (FFBI) [36] has been proposed to feed forward the video frame sizes in a stream of video frames and use them as bandwidth indications that can be utilised instead of bandwidth forecasts. FFBI can be also extended for use with live video by introducing a small delay at the video source [36].…”
