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 …

Abstract The 802.11 E 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 …

The spreading diffusion of wireless devices and the crowded coexistence of multimedia
applications greedy of bandwidth and with strict requirements stress the service provisioning …

The IEEE 802.11 e standard intends to enhance the Quality of Service (QoS) by introducing
Hybrid Coordination Function Controlled Channel Access (HCCA). In HCCA, the QoS …

IEEE 802.11 e HCCA reference scheduler is based on fixed value parameters that do not
adapt to traffic changes, thus quality of service (QoS) for multimedia applications is a …

Hybrid coordination function controlled channel access (HCCA) is a medium to enhance
quality of service (QoS) via the IEEE 802.11 e standard. The main limitation of HCAA is that it …

IEEE 802.11 e standard introduces HCF Controlled Channel Access (HCCA) to support
quality of service (QoS) for multimedia traffics. In HCCA, the traffics scheduled according to …

An effective method to assign TXOP for the multipolling mechanism (EMATMM) in high-
density WLAN is proposed by changing the TXOP and SI values in IEEE 802.11 e. In the …

With the increasing popularity of using Wireless Local Area Networks (WLANs) in a sense of
cost-effectiveness and easiness in deployment, the controlled channel access mechanism in …

The regular IEEE 802.11 e HCCA mode cannot guarantee the QoS support for the VBR
traffic. Hence, many researchers proposed new mechanisms by enhancing the regular …
