A rate adapted TCP acceleration for mobile wireless network
Sungwon Lee · 2009
FAST Transmission Control Protocol (TCP) was previously proposed for high capacity with long delay network environments, and `FAST TCP with Snoop' performs better than conventional TCP enhancements within mobile wireless network environments. However, FAST TCP has limitations when dealing with a dynamic mobile wireless link where high Frame Error Ratio (FER) and frequent delay changes due to variable rate. We propose an enhanced TCP acceleration algorithm at the TCP sender side which efficiently adapt to the maximum transmission rate of a mobile wireless link using Round Trip Time (RTT) and virtual Receiver Window (RWND) information. Also, the proposed algorithm provides superior performance over mobile wireless network environments.
