Abstract: The Transmission Control Protocol (TCP) is a widely used transport layer protocol for reliable IP networks. To handle congestion in the network due to various reasons many algorithms have been designed. In this paper, we have carried out a detailed analysis of the Elastic TCP congestion control algorithm which is based on delay and independent of Round-Trip Time (RTT). Elastic TCP uses a Window-correlated Weighting Function (WWF) for deciding the update of congestion window size. We have proposed an enhanced Elastic (e-Elastic) for further improvement of performance. These algorithms Elastic and e-Elastic are more suitable for the high and moderate Bandwidth-Delay Product (BDT) while we have tested it for moderate BDT on network simulator-3 (ns-3). Our proposed algorithm improves the average throughput with 5.11%, 10.14%, 10.69% and 11.07% over Elastic, CUBIC, Veno and New Reno, respectively.
