A COMPARATIVE STUDY OF EMBEDDED PROTOCOLS FOR SAFETY-CRITICAL CONTROL APPLICATIONS

Currently, distributed control systems (DCS) are becoming widely in used the embedded application domain. Especially in the automotive area, which is considering the possibility of replacing the major part of mechanical and/or hydraulic systems for electronic systems, the importance of reliable communication plays a key role. Nevertheless, it is necessary to understand and explore the facilities of the underlying communication platform in order to build reliable distributed control functions. In this context, this work presents a comparative analysis of embedded protocols focusing on the communication paradigm, which can be of type event-triggered or time-triggered. In addition, the timing behavior of a steer-by-wire model was extracted by simulating the system at the MAC network level, considering first a event-triggered and then a time-triggered protocol.
