Open Middleware proposal for IoT focused on Industry 4.0

The arrival of hyper-connectivity and digitization through Cloud/Fog Computing in the productive industry, and together with an adequate analysis and treatment of data generated in this new industrial digital world, are giving rise to the well-known 4th Industrial revolution, with the sole purpose of automating processes more effectively, therefore, new information and communication technologies have a determining role; however, the lack of standardization and unified criteria for the development of cross-cutting platforms are a problem for the proper deployment of IoT, heart of 4th Industrial Revolution. This research raises the possibility of using an MQTT-minded middleware, with MQTT as an on-demand messaging protocol, taking advantage of its native characteristics and benefits in order to achieve an adequate implementation ecosystem for this new paradigm in automation and process controls. A proof-of-concept testbed was developed to support the selection of MQTT as the IoT Middleware protocol proposal; as well as a High-Level Osmotic-type Middleware Architecture solution for the new 21st Century Industry was developed.
