The vision of cyber-physical systems (CPSs) considered the Internet as the future communication network for such systems. A challenge with this regard is to provide high communication reliability, especially, for CPSs applications in critical infrastructures. Examples include smart grid applications with reliability requirements between 99–99.9999% [2]. Even though the Internet is a cost effective...
Currently, cloud computing offers flexible, dynamic and cost effective computing outsourcing, but it limits these economic and operational benefits to non real-time and non safety-critical systems. This is because of the lack of alternative control, supported by current cloud infrastructures, in case of a broken cloud link. While steps have been taken in using cloud infrastructures for soft real-time...
For cyber-physical systems (CPSs), communications system reliability is an indispensable requirement to realize them in critical infrastructures. One of the important attributes of system reliability is availability. System availability is broadly defined as the proportion of time that the system will provide service. In some CPSs, such as smart grids, the units are distributed over large geographical...
Scheduling of time triggered communication systems belongs to the well known hard mathematical optimization problems. This paper tackles the communication scheduling problem in redundant network topologies, where the real-time process data has to be duplicated and sent on two different paths to its destination. This paper proposes an algorithm that is able to find a feasible schedule in a short time,...
