TCP Performance Analysis by Loss Differentiation Algorithm over Lossy Wireless Links
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 …
