Developing Internet of Things (IoT) systems has to cope with several challenges mainly because of the heterogeneity of the involved sub-systems and components. With the aim of conceiving languages and tools supporting the development of IoT systems, this paper presents the results of the study, which has been conducted to understand the current state of the art of existing platforms, and in particular low-code ones, for developing IoT systems. By analyzing sixteen platforms, a corresponding set of features has been identified to represent the functionalities and the services that each analyzed platform can support. We also identify the limitations of already existing approaches and discuss possible ways to improve and address them in the future.

物联网的低代码工程：研究状态

开发物联网 (IoT) 系统必须应对若干挑战，主要是因为所涉及的子系统和组件的异构性。为了构思支持物联网系统开发的语言和工具，本文介绍了研究的结果，该研究旨在了解现有平台的当前状态，尤其是低代码平台，用于开发物联网系统。通过分析 16 个平台，确定了一组相应的特征来表示每个分析平台可以支持的功能和服务。我们还确定了现有方法的局限性，并讨论了未来改进和解决这些问题的可能方法。
