WLAN, Coexistence and QoS.
The IEEE 802.11e amendment is being designed to be compatible with the legacy 802.11 standard, therefore users with 802.11 network card will be able to connect and work without problems in a new QoS Basic Service Set (QBSS). However, this coexistence may deteriorate QoS support provided by the new standard. In this paper the influence of 802.11b DCF stations on the QoS provision in IEEE 802.11e standard is analysed and new mechanism for performance improvement of legacy IEEE 802.11 stations is also proposed.
