Performance Analysis of IEEE 802.11 EDCA for a Different Number of Access Categories and Comparison with DCF

Performance analysis of the 802.11 EDCA and DCF using simulation and analytical model is presented. An impact of different number of ACs in the network performance is studied under nonsaturation and saturation network condition. Additionally, it is shown that the EDCA doesn’t provide a good prioritized access in contrast to the DCF, when only one traffic type is being transmitted through the wireless network.
