The IEEE 802.11 [1] currently used as the WLAN standard, specifies the distributed
coordination function (DCF), which is based on carrier sense multiple access with collision …

With the widespread IEEE 802.11 networks use, strong needs to enhance quality of service
(QoS) has appeared. The IEEE 802.11 medium access control (MAC) protocol provides a …

The basis of the Medium Access Control (MAC), proposed in IEEE 802.11 standard for
wireless local area networks, is the Distributed Coordination Function (DCF). DCF uses …

Abstract The release of IEEE 802.15. 4 medium access control (MAC) and physical layer
specifications represents a significant milestone in promoting deployment of wireless sensor …

The medium access control (MAC) protocol is the main element which determines the
system throughput in wireless local area networks. The MAC technique of the IEEE 802.11 …

Abstract IEEE 802.11-based wireless networks are becoming more popular, and a lot of
research is done to enhance the performance of the distributed control function (DCF) found …

In order to develop a contention-based MAC with quality of service (QoS) guarantee based
on the distributed coordination function (DCF), we investigate the backoff scheme. We …

Contention based MAC protocols are widely used in ad hoc networks because they are
suitable, where no central control node exists. However, contention based MAC protocols …

The medium access control (MAC) protocol in IEEE 802.11 wireless LAN employs
distributed coordination function (DCF) with binary exponential backoff (BEB) algorithm for …

Design of an efficient wireless medium access control (MAC) protocol is a challenging task
due to the time‐varying characteristics of wireless communication channel and different …
