Cognitive IoT platform for fog computing industrial applications

In this paper, we propose a fog computing (FC) application for industrial internet of things (IIoT). The need for the distributed intelligence application to the edge of the IIoT, achieved by fog computing paradigm, is first pointed out. To provide such a distributed intelligence, we propose the application of the cognitive IoT concept. A platform is deployed named cognitive IoT platform. A detailed presentation of the functional architecture is provided highlighting the required distributed intelligence through the cognitive agent application as key enabler for the embedded intelligence. In the sequel, we provide a particular FC application with a particular solution for predictive maintenance (PdM) in smart factory application. Experimental setup and tests are carried out using the platform in order to provide PdM-as-a service. The proof of concept follows with the corresponding results that demonstrate a real-world fog computing solution to the edge of an overall IoT architecture. (C) 2020 Elsevier Ltd. All rights reserved.
