Updated Congestion Control Algorithm for TCP Through Put Improvement in Wired and Wireless Network

The basic idea proposed in this paper is to determine the Optimal Congestion Window for a TCP Sender in a particular network set-up (that corresponds to the fair share of that connection) and keep this congestion window a constant to a point where the fair share in the network has changed considerably from the instance of the calculation of the size of the last window. At this point, the TCP Congestion Window is recalculated according to the nature of new circumstances. The proposed mechanism is particularly effective over wireless links, which have an inherently loss-prone nature, as Modified TCP's congestion window being independent of packet losses (be it corruption losses or it congestion losses), keeps transmitting at the same rate at before.
