Configuration of IEEE 802.11e EDCA for Voice and Data Traffic: An Experimental Study

In this paper, the authors conduct an experimental study of the Enhanced Distributed Channel Access (EDCA) mechanism of the IEEE 802.11e standard with a testbed consisting of 1 Access Point and 15 WLAN stations. The focus of their study is the proposal of guidelines for the configuration of the open parameters in the EDCA mechanism. Specifically, they aim at supporting two widely deployed applications nowadays: voice and data traffic. To their knowledge, this is the first attempt to propose concrete configuration guidelines for the support of these two application types. From the comparison of their proposed configuration against the one recommended by the standard, they show that their guidelines outperform the standard's by 20% to 40%, depending on the number of data stations present in the WLAN.
