Abstract
Transmission control protocol (TCP) suffers significant performance degradation over wireless networks where packet losses are not always caused by network congestion. In order to prevent frequent retransmission timeout (RTO), which is the main reason for the degradation, we propose enhancements that make it possible for a TCP sender to recover packet losses occurred during fast recovery period. The proposed scheme consists of two algorithms called Duplicate Acknowledgement Counting (DAC) and Extended Fast Recovery (EFR). Simulation results show that the proposed scheme improves the throughput of TCP NewReno by reducing the number of RTO.
