摘要
物联网技术已经引起国内学术界、工业界和新闻媒体的高度重视,当前物联网的定义、内在原理、体系结构和系统模型等方面还存在许多值得探讨的问题,通过对现有物联网技术文献和应用实例的分析,探讨了物联网与下一代网、网络化物理系统和无线传感器网络的关系;提出了物联网的服务类型和结点分类,设计了基于无源、有源和互联网结点的物联网的体系结构和系统模型;在总结物联网特征基础上,对物联网的研究提出了建议。
The technology of the Internet of Things (IOT) has attracted highly attention of academia,industry,and news media.There are still many open issues in the definition,internal principles,architectures and system models of IOT.Through the analysis of current technical materials and application cases of IOT,this paper discusses the relations between Next Generation Network,Cyber-Physical Systems,Wireless Sensor Network and the IOT.It proposes service types and node classification of IOT and designs the architecture and system model of IOT based on passive,active and internet nodes structure of IOT.After summary of the features of IOT,it proposes the suggestions on the researches and development of IOT.
