Abstract: Wireless networks are going to be pervasive, and hence it is almost impossible to keep ourselves away from this technology. But still wire network has its own significance, which can not be ignored due to its reliability. The major difference between both technologies is that wireless has more error prone attitude to packet transmission with respect to wired network. Among the available transport level protocol, TCP is the most prominent due to its characteristic and long term use in application. Rather than concentrating on new transport layer protocol, I have improved the present TCP congestion control mechanism so that it can be used universally on wired and wireless technology. One of the reasons behind the degradation of TCP congestion control mechanism performance is considering packet loss due to corruption in channel as network congestion. In this dissertation I have cast the idea of two windows for measuring the real congestion window and status of packet loss due to corruption in channel. Proposed algorithm changes real congestion window based on degree of packet loss due corruption in channel to increase in throughput of network. It has been tested on the network simulator NS3. results shows that congestion widow get affected only in case of packet loss due to high load rather than packet loss due to corruption in channel. It enhances the network throughput ratio significantly of such networks, which is susceptible to error, with respect to present TCP variant such as Tahoe, Reno and NewReno.
