TL;DR: The new hybrid coordination function of the IEEE 802.11e with its contention-based and contention-free (controlled) medium access control schemes is evaluated and the capability to provide QoS support is discussed by means of simulations.

TL;DR: The emerging 802.11 standard is overviewed and its finalized amendments and those under development are highlighted, to address the technical context of its extensions.

TL;DR: In this article, insights are provided into the latest developments in 802.11s and how the overall mesh concept fits into the 802 set of networking standards are explained.

TL;DR: In 2003, interests in the Institute of Electronics and Electrical Engineering (IEEE) 802.11 Working Group (WG) led to the formation of Task Group (TG) "s", which develops a Wireless Mesh Network (WMN) amendment and considers extensions to the Medium Access Control (MAC) too.

TL;DR: In this article, a distributed MAC protocol is provided that includes a superframe (102) having a slotted Beaconing Period (104) and a data transfer period (103), which defines initializing an ad hoc network by means of starting (101) a beaconing period, joining an existing beaconing Period, and resolving collisions during the beamforming period.
