TCP and its modeling in wired-cum-wireless networks Cire Sall

This paper aims to revisit the TCP congestion window model already proposed in the literature, and discusses some of its parameters in wired-cum-wireless networks. Clearly, an enhancement of the above mentioned model is proposed following new variants of TCP designed to work in such environments. This issue led us to derive a model estimating the effective throughput of TCP in such environments, which was validated by simulation under NS2. Finally, the efficiency of random marking used by active queue managements (AQM) implemented at base stations linking wired and wireless parts of a network is assessed; our simulation shows that a deterministic (non random) marking leads to better results with respect to a random one.
