A rate based TCP congestion control framework for cellular data networks

... not actually accurate indicators of link quality in cellular data networks Another proposal of performing TCP congestion control using the rate information is RATCP [37], which is not a practical ... Finally, we show that while forecasting techniques can decrease the delay in cellular data networks, it is not necessary as a quick reacting rate- based algorithm can al...
