Network and control relationship is an essentialaspect in the design of networked control systems (NCSs). Thedesign parameters are mainly centered in the transmission rateand in the packet structure, and some studies have been madeto determine how transmission rate affects the network delayand consequently the stability of the control. In Internet, theseanalysis are mathematically complex due to the large number ofdifferent potential scenarios. Using empirical methods, this workdeduces that the transmission scheduling problem of an NCS canbe solved by designing an appropriate transport protocol, takeninto account high and periodic sampling rates. The transportprotocol features are determined by simulation, using a newtest platform based on the NS2 network simulation suite, todevelop controletwork codesign solutions. Conclusions of thispaper are that the transport features are packet-loss-basedflow control, best effort, and fairness, supplemented by a packetpriority scheme.
