A simple algorithm for dynamic configuration of TXOP limit is proposed for the contention channel access mode, called Enhanced Distributed Channel Access (EDCA). The proposed scheme aims to define dynamic rules for TXOP duration adjustment in multimode IEEE 802.11e networks in order to improve system efficiency and provide better QoS provision.

However, if no control is applied to the legacy stations, this coexistence may deteriorate QoS support provided by the new IEEE 802.11e standard. In this paper the influence of IEEE
