PROJECT TITLE :

Traffic Generation Rate Control of Wireless Sensor and Actuator Networks

ABSTRACT:

The traffic generation rate of the network used for cyber-physical systems may be a crucial style parameter since it directly affects the steadiness of physical systems and also the congestion level of communication systems. In this paper, we tend to propose a completely unique modeling framework of the final wireless sensor and actuator networks of cyber-physical systems where the sensor-controller and controller-actuator sides communicate over a lossy network. The performance model is then used to derive the optimal traffic generation rate of sensors and controllers for minimizing the maximum outage likelihood of the steadiness constraint of the management systems whereas guaranteeing a schedulability constraint. The resulting downside is a non-linear optimization drawback which permits to get the worldwide optimum. An efficient approximation converts the proposed optimization drawback into a linear programming downside. One attention-grabbing finding is that the optimal resolution assigns higher traffic generate rate on the controller-actuator link compared to the one of the sensor-controller link since the actuating-link is more important to guarantee the stability of the control systems.
