Components of fog computing in an industrial internet of things context

The "Internet of Things" (IoT) represents an em- bodiment of the continuous convergence between the physical facet of human activities and its reflection on the informa- tion world. In the context of “Industrial Internet”, where the operation of complex physical machinery is integrated with networked sensors and software applications, IoT is under- stood as a technological enabler of significant advances in the efficiency of industrial processes. In this paper, we elaborate on the main challenges brought on by the Industrial Internet and identify its key enabling technologies relevant to the Fog Computing paradigm. Further on, we propose the introduction of an Adaptive Operations Platform (AOP) to provide end-to- end manageability of the enabling Fog Computing infrastructure according to the operational requirements of industrial process. We present our prototype setup for AOP and elaborate on its performance evaluation in a typical industrial scenario.
