Interest in finding methods of improving TCP performance over satellite and wireless networks is high. This has been an active area of research within the networking community. This research develops an algorithm, CETEN-R for TCP to determine if a particular packet is lost due to congestion or corruption and react accordingly. An analysis of the performance of CETEN-R under a variety of conditions is studied and then compared to TCP Reno and TCP New Reno. When delay is high and the error rate is high CETEN-R showed a 77.5 increase in goodput over TCP New Reno and a 33.8 increase in goodput over TCP Reno. When delay is low and the error rate is high, CETEN-R showed a 146 increase in goodput over TCP New Reno and a 77 increase in goodput over TCP Reno. At low error rates, CETEN-R provides no advantage over TCP Reno or TCP New Reno.
