Degradation of the performance of TCP because of errors in transmission media has always a Key area of research. In recent years, the demand for network bandwidth is growing due to increase in global population of internet and verity of application. Congestion is the major problem in today’s internet. So, for managing traffic and to keep the network stable, Congestion Control algorithms are used. TCP protocol is basically designed for wired network need to be modified for the wireless network. In wired network, TCP works well, but in wireless network the data losses are occurred. The losses of data are occurred because of not only congestion, but random bit error is also reason for data losses over wireless link. TCP has been modified by various add on techniques to achieve a desired performance level in heterogeneous environments. TCP is responsible for flow, error and congestion control which has a direct impact on network performance and service. Among TCP variants, SACK TCP is considered as the most stable and efficient scheme.
