Description

The IEEE 802.11 standard supports two MAC mechanisms, the Distributed Coordination Function (DCF) and the Point Coordination Function (PCF). These mechanisms are considered to be insufficient for achieving a reasonable quality in scenarios with high background load. Thus, QoS enhancements are vividly studied and evaluated. The QoS enhancements developed by the IEEE 802.11e WG have been under design for several years. The amendment to the 802.11 standard was finally approved and published in November 2005. Basically, IEEE 802.11e introduces two additional MAC modes: the Enhanced Distributed Channel Access (EDCA) and the HCF Controlled Channel Access (HCCA), which have been derived from their earlier versions EDCF (Enhanced Distributed Channel Function) and HCF (Hybrid Coordination Function) of previous drafts.
