Traffic generation for wireless network control systems (WNCS) is a very important design parameter that directly affects the stability of control systems and the level of congestion of communication systems. This paper proposes a framework for modelling wireless sensor and actuator networks in the WNCS, where the exchange of data from the sensor to the controller and from the controller to the actuator communicates through a lossy network. The performance model is used to obtain the optimum speed of traffic generation from sensors and controllers to minimize the maximum probability of interruption of the stability restriction of the control systems. The resulting problem is a non-linear optimization problem that allows the overall optimum to be obtained. An efficient approach turns the proposed optimization problem into a linear programming problem. From the respective simulation it is proposed that the optimal solution assigns a higher traffic generation speed in the controller-actuator link compared to the sensor-controller link, since the action link is more critical to guarantee the stability of the systems control.
