Abstract

TCP continues to be an important transport-layer communication protocol that is typically tuned to perform well in traditional wired networks, where bit error rate is low and congestion is the primary cause of packet loss. Wireless networks are prone to High BER, which is responsible for large number of packet losses. TCP incorrectly interprets these losses as signs of network congestion and throttles its transmission rate unnecessarily, which degrades end-to-end performance in wireless networks. Objective is to distinguish between congestion loss and wireless loss and to fine tune the TCP to perform well in wireless environment using Loss Differentiation Algorithm.
