Design of a Fog Controller to Provide an IoT Middleware with Hierarchical Interaction Capability

With a large number of IoT devices currently and growing, it is of great importance to orchestrate them so that all exercises are fully functioning. This project focuses on the creation of low-cost IoT middleware capable of decentralizing responsibilities, processing, and decision making in a network. This work addresses the construction of an IoT middleware itself, showing the pillars based on its construction - using microservices in its composition - from the storage of information, dealing with particularities of the proposed architecture, up to its ability to react to certain scenarios. It also presents how to use fog concepts to decentralize middleware responsibilities at different points in a hierarchy in an IoT network. Finally, it is commented on the limitations of the following project and possible parts for improvement to be considered in future projects.
