Context-Aware Fog Computing Implementation for Industrial Internet of Things

The connectivity of devices has increased in the last decade enabling multiple innovative applications and solutions to serve industries and societies. This has solved multiple challenges and facilitated the improvement of methodologies and techniques adapted by humanity. One of the newly created paradigms that changed industries and technology is the Industrial Internet of Things (IIoT). IIoT is currently being adapted by various industries creating interactive supply chain ecosystems through the use of cloud computing. The size and distributions of these ecosystems introduced latency and Quality of Service (QoS) issues for edge devices sending data to the cloud. This research paper explores a paradigm called “Fog Computing” which aims to reduce the latency between IIoT devices and the cloud by deploying a “cloud-like” computing layer closer to the IIoT devices. In addition, a Context-Aware implementation of fog computing is proposed in this paper to provide the most optimised service to edge devices. Furthermore, this paper includes various experiments that examine the different context-awareness perspectives this paper proposes for fog computing. The results and outcomes of these experiments show reduction in latency and automated resource scaling from the use of context-awareness with fog computing over cloud computing for IIoT.
