Dynamic TXOP configuration for Qos enhancement in IEEE 802.11e wireless LAN

Abstract

This paper presents a study on transmission opportunity (TXOP) mechanism of the new MAC protocol described in the IEEE 802.11e supplement to the standard. 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
