In this paper an adaptive ACs (Access Categories) number adjusting algorithm for the EDCA (Enhanced Distributed Channel Access) scheme is proposed. It has been shown that the total performance of the wireless network can be enhanced especially under the highly loaded network conditions. It has been introduced as a result of collecting a data buffer and the switching mechanism for AC queues. The simulation results demonstrate that the proposed adaptive ACs number adjusting algorithm for the EDCA scheme outperforms significantly the 802.11 specification. This outperformance of wireless network is observed under the large network size and high network load.
