A High Performance and Efficient TCP Variant

With emergence of the latest technology and deployment of wireless mobile networks for data communication services, the need of the people has also been increased. There has been a significant effort to tune TCP for these networks. The performance of TCP is affected due to several factors including the congestion window, maximum packet size; retry limit, recovery mechanism, backup mechanism and mobility. The proposed TCP variants are successful in fixed networks but did not yield good results in a mobile wireless network. In this Work, we propose a new TCP variant named UB by integrating the features of TCP Westwood and Vegas. TCP-UB provides better performance than the other TCP variants from the mobility point of view. We have simulated our algorithm using NS2.28 which shows that TCP-UB achieves superior performance over TCP Vegas and Westwood.
