Abstract :
The performance of TCP flows over rate-adaptive wireless LAN (WLAN) is investigated. Therefore, an analytical model of WLAN from our previous work is enhanced to include multiple TCP down-link flows. Modelling TCP´s flow and congestion control over rate adaptive WLAN required to solve an M/G/1/B queueing system and a set of non-linear equations. The results are verified with simulations and show that the main performance influencing parameters are the locations of the users and of course the number of these. We show for several scenarios the TCP throughput that users can expect
