The EDCA mechanism of the IEEE 802.11 standard has been designed to support, among
others, video traffic. This mechanism relies on a number of parameters whose configuration …

The MAC layer of the 802.11 standard, based on the CSMA/CA mechanism, specifies a set
of parameters to control the aggressiveness of stations when trying to access the channel …

Streaming multimedia content in real‐time over a wireless link is a challenging task because
of the rapid fluctuations in link conditions that can occur due to movement, interference, and …

Although the EDCA access mechanism of the 802.11 e standard supports legacy DCF
stations, the presence of DCF stations in the WLAN jeopardizes the provisioning of the …

The minimum contention window () value of the EDCA protocol gives priority access to the
different categories of traffic on the WLAN and also affects the rate of collision and delays …

The volume of video streaming traffic over the Internet has increased dramatically over the
last 10 years. By the end of 2014, it is expected that 77% of the US internet traffic will be …

This paper presents efficient mechanisms for delay-sensitive transmission of video over
IEEE 802.11 a/e wireless local area networks (WLANs). Transmitting video over WLANs in …

One of the main challenges with 802.11 e EDCA is the configuration of the open parameters
of this mechanism, namely AIFS, CWmin, CWmax and TXOP_limit. In this paper, we address …

In this paper, we give an analytical justification how to control the QoS parameters using a
throughput approximation model for IEEE 802.11 e EDCA. Using the model, we propose a …

In this paper, we analyze the issues involved in developing a system based on the IEEE
802.11 e draft proposal, which defines medium access control (MAC) procedures to support …
