This paper is concerned with infrastructure mode WLANs that use the IEEE 802.11 DCF mechanism. The authors are interested in analytical models for evaluating the performance of TCP controlled simultaneous uploads and downloads where each connection has arbitrary TCP windows size. A detailed analysis of the aggregate throughput of TCP download in a WLAN for a single rate Access Point (AP) is given in by assuming constant TCP windows for all the links. Similarly aggregate throughput of the AP is evaluated for the multi rate cases are in. However these works also consider either only downloads or uploads with constant windows.
