Abstract: - Transport Control Protocol (TCP), the mostly used transport protocol, performs well over wired networks. TCP Congestion control plays the key role to ensure stability of the Internet along with fair and efficient allocation of the bandwidth. So, congestion control is currently a large area of research and concern in the network community. During the last decade, several congestion control mechanisms have been proposed to improve TCP congestion control. Comparing these mechanisms, showing their differences and their improvements, and we identify, classify, and discuss some of these mechanisms of TCP congestion control such as Tahoe, Sack, Reno, New Reno, Vegas, and Westwood. TCP Westwood works for both wired and wireless network, and we propose a new algorithm called TCP West wood New to increase the performance of TCP-Westwood. We simulate the proposed algorithm TCP West wood New using the well known network simulator ns-2, by comparing it to the original TCP-Westwood. Simulation results show that the proposed scheme achieves better throughput than TCP Westwood and decreases the delay.
