| Abstract: | The limitations of the DCF(Distributed Coordination Function), a basic access mechanism of IEEE 802.11 Wireless LAN, in supporting Quality of Service(QoS) are discussed. EDCF (Enhanced DCF), a new access mechanism adopted by the future IEEE 802.11e standard for QoS support, is analyzed. The performance of EDCF is simulated and an analysis of simulation results is made against the performance of the original IEEE 802.11 DCF. |
