The impact of transmit buffer on EDCA with frame-bursting option for wireless networks

Enhanced distributed channel access (EDCA) is a contention-based scheme of the 802.11e proposal. To allow a station to transmit more than one frame, an optional feature known as controlled frame-bursting (CFB) is introduced in its proposal. We perform a detailed evaluation of the EDCA protocol with the CFB option to quantify its performance gain. The impact of the MAC transmit buffer size is also incorporated. Accordingly, we propose a suitable approach to guide the configuration of the burst limit.
