This paper presents a mathematical model for evaluating TCP flows behaviors in WLAN. Now a days Downstream flows play an important role in traffic of a wireless networks. In many networks TCP downstream flows have less throughput than upstream flows. Simulated results of our proposed scenario show base station buffer size cause unfairness between flows. This unfairness specially injures downstream flows throughput. Our main goal is demonstrating this tow flow behaviors by simulating a proposed scenario and presenting an analytical and mathematical model for evaluating these flows behavior. You will see if the base station buffer size be larger than 1.5 time of TCP receiver window size, the throughput of tow flows is nearly equal hence accessing the sharing bandwidth remains fair INDEX TERMS: WLAN,TCP, throughput, downstream flow, upstream flow, glomosim simulator.
