Performance Improvement of TCP by TCP Reno and SACK Acknowledgement
Transmission Control Protocol (TCP) is the dominating end-to-end transport layer protocol which provides secure and reliable data transfer together with some other protocols. In this review paper, the authors contend that existing approaches to improve TCP performance over mobile ad-hoc networks have focused only on a subset of the factors affecting TCP performance by TCP Reno, SACK and Vegas. Effective resource utilization, such as bandwidth utilization, retransmission rate and window size, is compared. for evaluate these TCP congestion control algorithms from many aspects are present and they also concern fair resource allocation from two main categories, one is fairness between different delay links, and the other is competition between different TCP congestion control algorithms.
