Abstract

We present a model for characterising the behaviour of the buffer at a base station router when TCP flow control is used in combination with a link layer retransmission protocol over a cellular wireless link. We show how our model can be used to predict packet latency, optimally dimension the buffer, and tune TCP to ensure maximum utilisation of the link, for specific wireless channel conditions. Finally we verify the model with simulation results obtained using the NS-2 simulator
