IEEE 802.11 standard provides two access mechanisms for its distributed coordination
function (DCF) protocol, the default basic access mechanism and the optional request-to …

This paper proposes and studies performance of the IEEE 802.11 distributed coordination
function (DCF) with new backoff functions, which are analyzed under saturation conditions …

This study investigates a comparison between Enhanced Distribution Channel Access
(EDCA) against the “legacy” IEEE 802.11 Distributed Coordination Function (DCF) method …

Wireless local area networks (WLANs) based on IEEE 802.11 Distributed Coordination
Function (DCF) have been widely used in many industry. This paper mainly analyzes the …

We propose a new design of success prioritized distributed coordination function (SP-DCF)
based on the backoff mechanism of IEEE 802.11 DCF to prioritize the station (STA) after …

In IEEE 802.11 wireless local area networks (WLANs), an important technique for medium
access control (MAC) is the distributed coordination function (DCF). Two access …

Most of analytical models proposed so far for the IEEE 802.11 distributed coordination
function (DCF) focus on saturation performance. In this paper, we develop an analytic model …

In this paper, we propose a mechanism named modified backoff (MB) mechanism to
decrease the channel idle time in IEEE 802.11 distributed coordination function (DCF). In the …

In contention-based wireless networks, the efficiency of channel access mechanism is
greatly affected by the contention level. The basic channel access mechanism, ie distributed …

The IEEE 802.11 is the most dominating protocol in the wireless local area networks and in
which, the fundamental mechanism to access the channel is called distributed coordination …
