Проведено порівняльний аналіз пропускної здатності двох схем доступу безпровідних мереж DCF та EDCA в умовах насиченої завантаженості.
This paper is devoted to the comparison analysis of wireless networks access schemes DCF and EDCA in case of saturation condition.
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.
