Abstract
The upcoming IEEE 802.11e is an extension of the 802.11 Wireless Local Area Network (WLAN) standard for provisioning of Quality of Service (QoS). This paper discusses the problem of QoS support in 802.11e in coexistence scenarios. As long as a set of 802.11e-stations operate without any other competing stations in the area, QoS can be guaranteed by a central coordinator, using polling techniques. However, in the situation of overlapping sets of 802.11e-stations, all stations support priorities between different data streams, but cannot guarantee any QoS, because of the uncoordinated access to the common radio channel. An approach to model such a competition scenario is the stage-based game model in which players try to maximize their benefits. The extension of the game on multi stage games covers the dynamic effects of the competition. The intention of the model is the definition of an etiquette, i.e., a framework for the player's interaction, to establish cooperation under which adaptive QoS support is achieved.
