Theoretical maximum throughput of IEEE 802.11e EDCA mechanism

The goal of this paper is to validate a formulae, originally derived to calculate the throughout upper bound of the IEEE 802.11 networks, over a single Access Point (AP) based WLAN system combined with the IEEE 802.11e EDCA mechanism. In this paper some important assumptions are made to keep the formulae very simple. The most important assumption is that, the AP is providing service to client nodes with only one type of Access Category (AC) traffic at an instant. Comparing both the theoretically achieved maximum throughput and simulation results, for different access categories (ACs) and for different packet sizes we observed that the formulae is pretty much accurate except for only one test case.
