This paper presents a unique approach for a model-based admission control algorithm for
the IEEE 802.11 e enhanced distributed channel access (EDCA) standard. The analytical …

The EDCA (Enhanced Distributed Channel Access) mechanism proposed in the IEEE
802.11 e draft, allows differentiating traffic channel access with different priorities. However …

Although IEEE 802.11 based wireless local area networks have become more and more
popular due to low cost and easy deployment, they can only provide best effort services and …

The provision of quality of service (QoS) in wireless network becomes very important. IEEE
802.11 e standard was introduced to enhance the media access control (MAC) layer …

Call Admission Control is one of the main mechanisms allowing an efficient protection of
active flows, especially on a wireless network using a distributed access scheme as is the …

One of the main quality of service mechanisms, allowing mainly the protection of already
active flows, is admission control. This is even truer on the MAC level of 802.11 based …

Extensive research addressing IEEE 802.11 e enhanced distributed channel access (EDCA)
performance analysis, by means of analytical models, exist in the literature. It started mainly …

We propose an admission control mechanism for 802.11 e WLANs that is based on the
measurement of important metrics characterizing the radio channel, and is integrated with …

IEEE 802.11 e is being proposed to improve QoS (Quality of Service) by IEEE 802.11
working group. HCCA (HCF Controlled Channel Access), a centralized polling based …
