Paper Details

Now a day’s use of wireless networks for access the Internet is increasing. It shows that use of themain transport layer protocol TCP will be increase in near future. The traditional TCP suffer from packet losses andthroughput degradation over wireless link. To improve performance of the TCP New Reno, so many variants of theTCP have been proposed like TCP Reno, New Reno, Tahoe, and Westwood etc. But no one has been de ployingsuccessfully except TCP New Reno.TCP New Reno shows improvement in throughput over Reno and SACK inwireless network. But TCP New Reno does not differentiate issue of packet loss due to congestion or bit error. So italways decrease cwnd (congestion window) in all issues of packet loss and degrade the performance. This paperproposes to improve the performance of TCP New Reno by differentiate issue of packet loss through eithercongestion or bit error. In our study we seen that New Reno gives us better performance in wireless link forthroughput, delay and packet delivery ratio. In recent research, New reno can differentiate bit error andcongestion control loss.
