Análisis comparativo entre arquitecturas de sistemas IoT

IoT systems are one of the current solutions for process automation. Its development is important to present solutions that adapt to new technologies. Despite its degree of use, there is not a unique architecture or reference model standardized that allows the development of an IoT system in a simple way. Developing an IoT system can be even more complicated when you don't have a unique guide. The present article makes a comparative study of two architectures and one reference model used for the development of IoT systems. The characteristics and functionalities of the selected cases will be exposed, and they will be compared to know the advantages and disadvantages of their use. The goal is to obtain a guide for the choice of an architecture or model for the realization of an IoT system, which has a support for its use; that is, it has already been used.
