RESEARCH NOTES: Design of a Distributed and Highly Scalable Fog Architecture for Heterogeneous IoT Infrastructures

Fog computing can provide an effective solution to the challenges presented by today’s ever-emerging Internet of Things (IoT) infrastructures. As the number of interconnected devices progressively increases, these infrastructures require better solutions to ensure high scalability and processing capacity, along with an efficient use of available resources. This is why this paper presents a distributed Fog architecture, specifically designed to address the challenges and difficulties presented by heterogeneous IoT environments. This Fog architecture is used as an intermediate layer between the IoT devices and the final layer, it has been designed after the previous analysis of the requirements to be met for the solution, then the modularization of the architecture has been carried out so that it can be easily distributed, and finally, an implementation has been generated on a real environment as a validation case of the proposal.
