Soluções IoT com atuação em Edge computing na Indústria 4.0: uma arquitetura de referência

Abstract

The demand for Edge Computing solutions in Industry 4.0 is increasing, especially in production environments that require real-time decision-making. However, implementing Edge Computing in industrial networks based on the Internet of Things (IoT) poses significant challenges, such as interoperability, low latency, and scalability. To support software architects in defining architectures for this context, this work proposes a Reference Architecture (RA) named ED-operator RA. The development of ED-operator RA was based on a Systematic Literature Review (SLR), through which relevant artifacts were identified, including non-functional requirements, software solutions, middleware, and other reference architectures previously proposed in the literature. The proposed architecture was modeled using multiple architectural views, including context view, container and module view, deployment view, control flow view, and data flow view. To ensure the validity of the architecture, this work presents an architectural evaluation based on the SAAM (Scenario-Based Architecture Analysis Method), supported by an experiment conducted using a prototype of the ED-operator RA. As a result, the ED-operator RA consistently demonstrated compliance with the defined requirements, reconciling scalability, interoperability, security, privacy, and low latency in IoT environments based on Edge Computing. Furthermore, this study provides a structured and reproducible methodology for the development and evaluation of reference architectures.
