Abstract
The focus of this work is to study the efficacy of
TCP's flow control algorithm on mobile phones. Specifically, we
identify the design limitations of the algorithm when operating in
environments, such as mobile phones, where flow control assumes
greater importance because of device resource limitations. We
then propose an adaptive flow control (AFC) algorithm for TCP
that relies not just on the available buffer space but also on
the application read-rate at the receiver. We show, using NS2
simulations, that AFC can provide considerable performance
benefits over classical TCP flow control.
