Fog Computing as Enabler for Blockchain-Based IIoT App Marketplaces - A Case Study

Fog Computing, Augmented Reality (AR) and Blockchain are technologies that have been receiving more attention in recent years. Fog Computing for on-site data analysis and Blockchain as a decentralized framework are used to establish security and trust. AR enables new interactive scenarios with devices in the industrial environment and provides user interfaces for devices that had previously lacked one. The combination of these technologies in an industrial environment opens up new possibilities and opportunities. We present the IIoT Bazaar, a decentralized marketplace for industrial edge applications that relies on Blockchain to create transparency for all stakeholders involved and to enable the traceability of app installations on edge devices. With Fog Computing, resource-limited edge devices can be integrated into the IIoT Bazaar ecosystem. Fog Nodes enable the provisioning of applications on edge devices and their integration into a decentralized Blockchain network. AR serves as an interface between the users and the machines, allowing people to interact intuitively with the edge devices. With a case study, we demonstrate the design and prototypical implementation of the IIoT Bazaar and its applications which bring software developers and users together using a combination of Fog Computing, AR, and Blockchain. We share the challenges we faced and our experiences we made during the case study.
