A workload distribution problem model and online constraint forming technique for the control systems in the fog-computing environment

Abstract

Abstract The paper deals with the workload distribution problem in the fog-computing environments. This problem is topical due to the wide range of networked control systems functioning on the basis of cloud and fog-computing infrastructure. The latter presupposes the techniques of workload relocation between the cloud, fog, and, in particular, the endpoint devices. As control systems have their own requirements in terms of latency, reliability, fault-tolerance, etc., the specific techniques must be developed to deliver these particular features using the fog-computing infrastructure. In the current paper a problem model of workload relocation is presented, the problem of constraints forming is considered and the new constraint forming technique is proposed.
