Abstract: In order to solve the problems of the transmission model of the wireless network control system, the mathematical model between the network latency and packet data loss was built, the full wireless features were supplied for the controller design. A simulation model of wireless network was established using the network simulation toolbox TrueTime based on the Matlab/Simulink. All nodes in this simulation model could move freely, and the mode had several interference nodes, the AODV routing protocols were adopted to choose routing, for implementing the communication between two nodes. Then via simulation, the sending and receiving time of the two nodes communication was recorded. The experimental results show that this simulation model could simulate the communication among the sensor, actuator and controller, be the simulation model to investigate the transmission model of the wireless network control system.
