Abstract: “TCP is the most popular end to end communication protocol in wired as well as wireless communication networks. At any point of time during the communication using TCP it is the size of the congestion window (cwnd) which determines the performance of the TCP. In this paper, we propose a new version of TCP: TCP-RP. TCP-RP uses fuzzy logic to determine optimum cwnd size during the Slow Start and Congestion Avoidance phase of TCP and improves network performance.”
