One of the keys to the success of the Internet is relying on using efficient congestion control mechanisms. Congestion control is required not only to prevent congestion collapse in the network, but also to improve network utilization. Without congestion control, a sending node may continue transmitting packets that may be dropped later due to congestion collapse. This paper presents a modified fast recovery algorithm to enhance the performance of the most widespread congestion control protocol; TCP-NewReno. The proposed mechanism is evaluated by using the network simulator NS-2 and compared with both the TCP-NewReno and the TCP-Reno. The simulation results show that the proposed mechanism improves the performance of the TCP-NewReno against throughput and packet delay.
