As wireless networks are deployed widely and user expectations grow, it is important to study the trade-offs among good put, latency and loss rates that exist in link and transport protocols. Under low residual loss rates, retransmissions can be effective in bringing down the loss rate. However, at high loss rates, current links trade-off good put and low latency for a small loss rate which diminishes overall performance. The authors look at the performance at the link and transport layers in the presence of raw loss and see how current protocols make an unattractive trade-off at the link layer.
