Abstract

Distributed embedded systems have become larger, more complex and complicated. More often, such systems operate accordingly to the IoT or Industry 4.0 concept. However, large number of end modules operating in the system leads to a significant load and consequently, to an overload of the communication interfaces. The CloudBus protocol is one of the methods which is used for data exchange and concurrent process synchronization in the distributed systems. It allows the significant savings in the amount of transmitted data between end modules, especially when compared with the other protocols used in the industry. Nevertheless, basic version of the protocol does not protect against the system failure in the event of failure of one of the nodes. This paper proposes four novel variants of the CloudBus protocol, which allow the fault detection. The comparison and performance analysis was executed for all proposed CloudBus variants. The verification and behavior analysis of the distributed systems were performed on SoC hardware research platform. Furthermore, a simple test application was proposed. [ABSTRACT FROM AUTHOR]

17. Interpreted hierarchical Petri nets in digital controller design

Author

Andrzejewski Grzegorz and Karatkevich Andrei G.

Abstract

An approach to describe behavior of the embedded systems of logical control implementing concurrent algorithms is considered. A strictly defined model based on interpreted hierarchical Petri nets is used for specifying the control algorithms. The model allows efficient implementation in microcontrollers. Analysis and verification of the concurrent systems are discussed; the analysis algorithms for the considered model are presented.
