Ibrahim Lawal Abdullahi, Steve Adetunji Adeshina, Felix Kalu · 2021
This paper introduces the concept of blockchain-based fog computing for Internet of things (IoT) by reviewing some similar works in the research area of the paradigm. The review of trends and challenges in this paper performs an analysis of related works in the literature review to identify some of the established gaps by researchers, then breaks down the key technologies individually while highlighting their alignment with the other technologies that form the paradigm. This work further identifies and highlights the key areas for improvement in the design consideration. Based on current research in the area, the paper outlines concepts on how blockchain technology could best be suited for fog computing in an IoT setting. The paper concludes by suggesting a future area of research in the domain.
