Abstract: Aiming at the limitation of the traditional Transmission Control Protocol(TCP) control protocol used in the heterogeneous network, in the use of grey correlation analysis on the basis of network parameters, this paper puts forward a TCP-N protocol based on the round delay jitter product differentiating packet loss. According to the measured round delay jitter product, this algorithm constructs membership function, it differentiates wireless error packet loss and network congestion packet loss according to the membership degree to the corresponding congestion control. Simulation experimental results show that compared with the traditional TCP protocol, TCP-N can more accurately differentiate the wireless error loss from congestion loss in heterogeneous network, improve the TCP throughput and bandwidth utilization, and improves network performance.
