NTA-IOT: A FLEXIBLE AND MODULAR ARCHITECTURE FOR IOT APPLICATIONS

Resumo

This work introduces the NTA-IoT, an abstract IoT architecture that is intended to be flexible and modular, in order to serve as a generic guide tool for developing IoT projects. The model is composed of two types of layers: base layers and support layers, with each layer providing a particular service in the IoT infrastructure. Some considerations and possible roles for building IoT projects following the NTA-IoT architecture are also detailed. Finally, this paper presents an example of a concrete implementation of the architecture on a home automation problem, based on the use of different technologies such as KNX, MQTT and the Outsystems platform to build a functional end-to-end IoT project. The correct functioning of this implementation shows that the architecture is, in fact, consistent and well-suited to serve as strategic guide to carry IoT projects with satisfactory results. Although the case study presented in this work is applied to home automation, the framework is hoped to be applicable to any type of project.
