You are provided with the abstract of a scientific paper and the abstracts of the papers it references. Your task is to write a Related Work section for the main paper. This section should concisely summarize and integrate the key points from the cited abstracts, reflecting how they relate to the main paper's contributions and context. In your summary, use numerical citation markers like [1], [2], etc., to refer to the corresponding papers.

Main Abstract:
In a multirate WLAN with a single access point (AP) and several stations (STAs), we obtain analytical expressions for TCP-controlled long file transfer throughputs allowing nonzero propagation delays between the file server and STAs. We extend our earlier work in [3] to obtain AP and STA throughputs in a multirate WLAN, and use these in a closed BCMP queueing network model to obtain TCP throughputs. Simulation show that our approach is able to predict observed throughputs with a high degree of accuracy.

[1]: In this paper we develop an analytic model of the behaviour of competing TCP flows in wireless networks. A key feature of this work is that we take explicit account of the interactions between competing TCP flows. This allows us to study issues such as responsiveness and the impact of the flow AIMD parameters on fairness.
Numerous models and analyses have been proposed for wireless networks with TCP-controlled traffic, but very few consider propagation delays. In [1] , RTT is considered in modelling the TCP traffic in a WLAN. However, the authors' interest was in showing that 802.11e supports features that can be exploited to overcome certain TCP performance anomalies.
