In order to tackle the controller synthesis problem for large-scale discrete-event systems, recent approaches suggest the design of interacting modular or decentralized supervisors. In these works, information exchange between the supervisors is either required implicitly by the synchronization of shared events or explicitly by the communication of events or symbols. However, it is not discussed how...
The synthesis of efficient distributed discrete-event controllers that are potentially implemented in networked controller devices has been extensively studied in recent years. However, different from the controller synthesis, the realization of such controllers on a network requires the additional consideration of timing issues due to the communication. To this end, we present a communication model...
Feedback control systems, of which control loops are closed over a real-time communication network, are called Networked Control Systems (NCSs). In this study, the message scheduling problem for NCSs with time slotted communication protocols is tackled. First, an algorithmic approach is presented to check the necessary and sufficient conditions for a given message schedule such that the real-time...
In the recent years, bus-based communication protocols have been developed to support time-critical applications in in-vehicle communication. In this respect, the FlexRay protocol is likely to become the de-facto standard. In this paper, we investigate the scheduling problem of periodic messages in the static segment of the FlexRay protocol. We determine a message schedule such that the available...
Today, peer-to-peer (P2P) traffic consumes the largest fraction of network bandwidth. The files shared by P2P communications are mostly copyright protected, and there are issues related to Quality of Service (QoS) support and billing of P2P traffic. Hence, scalable and accurate detection of peer-to-peer (P2P) traffic is a significant problem for network service providers. Flow-based detection methods...
Crosscutting concerns are the issues in object- oriented programming (OOP) that cannot be modularized within a software module. In this paper, an experimental evaluation of the use of aspect-oriented programming (AOP) for the implementation of crosscutting concerns in embedded real-time systems is presented. The crosscutting functionality of the project under study is realized both by employing OOP...
Recently, several efficient supervisor synthesis approaches for distributed discrete event systems (DES) have been established. In this paper, the implementation of such supervisors on interacting distributed programmable logic controllers (PLCs) on a network is considered for the hierarchical and decentralized control approach elaborated in our previous work. A communication model that captures the...
