Simulation Study of TCP/IP Communication Based on Networked Control Systems

This paper studies the TCP/IP communication issue of data stream in networked control systems (NCS). The character of the NCS is analyzed and the data stream type is discussed. Analytic model of TCP/IP is presented according to slow start theory. The simulation model is established based on OPNET software. The performance result of different type of data stream TCP/IP transmission is presented. Finally, the simulation result is analyzed, and defects and improved method of TCP/IP protocol is discussed
