物联网信息模型与能力分析

虽然近几年物联网技术开发与应用快速增长，但物联网理论研究仍然处于发展阶段.物联网作为一个典型的信息与通信系统，不仅具有现有互联网的信息存储和传递的能力，而且具有物品信息的自动采集和处理能力.构建物联网信息模型是分析物联网特征能力的一种有效方法.根据国际电信联盟有关物联网的定义和特征描述，通过采用统一建模语言构建物联网信息模型，分析和验证了物联网的物品相关能力、自主操作能力以及隐私保护能力，讨论了物联网信息模型在物联网技术标准方面的指导性结论，分析了物联网信息模型在讨论有争议的物联网概念或观点方面的应用价值.

Information Model and Capability Analysis of the Internet of Things

While the technical development and applications of the Internet of things (IoT) grow rapidly in recent years, the theoretical research of the IoT is still in the developing stage. The IoT is a typical information and communication system. It possesses not only the capabilities of storing and transferring information as with the existing Internet, but also the capabilities of automatic capturing and processing the information of things. The IoT information modeling is an effective method to analyze the characteristic capabilities of the IoT. In this paper, an information model of the IoT is described by unified modeling language according to the definition and characteristics of the IoT specified by International Telecommunication Union (ITU). The capabilities of things association, autonomic operation, and privacy protection are analyzed and validated based on the information model of the IoT. The conclusions of guiding the standardization of the IoT technology from the information model of the IoT are discussed, and the values of the IoT information model in resolving the issues of debated concepts or opinions of the IoT are analyzed.
