| Abstract | This paper investigates performance behaviour of TCP sessions when supported over IEEE 802.11b Wireless LANs. We emphasize the interaction between uplink/downlink TCP fairness and link layer parameters or Access Point buffer provisioning. The novel aspect is that this investigation is fully made in an experimental environment. We prove that TCP suffers of some inequalities that derive to unfair bandwidth sharing between uplink and downlink. Our extensive experimental analysis shows the main effects of these inequalities on the TCP behavior and highlights some performance anomalies that are difficult to be measured via simulations. A simple, but effective, scheduling mechanism is then provided within the Access Point to alleviate the unfairness. |
