The scheduling of the exchanged messages is an essential mechanism in the context of Networked Control Systems. The more often, the scheduling is based on static priorities but this scheme has shown limits when process control applications are considered. These limits have yet been demonstrated by the authors by considering a Networked Control System implemented on the Fielbus CAN. The goal of this...
Collision-free Medium Access Control (MAC) protocols based on Carrier Sense Multiple Access (CSMA) and priorities associated to the frames are interesting solutions in considering real-time traffic in a wireless context. We have already presented such a protocol using priorities represented by the BlackBurst technique [1]. The goal of this paper is, at first and mainly, to specify another such protocol,...
We consider, by means of a study based on a simulation, the implementation of process control applications on a Wireless Local Area Network (WLAN) with a collision-free CSMA MAC protocol called CANlike protocol (adaptation of the MAC protocol of the CAN bus to the wireless context). The co-design approach is based on links between the Quality of Control (QoC) provided by the controller and the Quality...
