The Research Of Perception Layer Structure Of Things

The Internet of things is a revolutionary development following the computer,Internet and mobile communication.In recent years,it is widely used in industrial monitoring,health care,intelligent traffic,and so on.The research on the Internet of things has been increasingly attached great importance by governments,academic circles and industry,and many new technologies continue to appear.The Internet of Things can be divided into three parts: one is the sensory layer,the other is the application layer,and the third is the network layer.The main study of this article is the Sensory layer of the Internet of things.Sensory layer refers to a combination of devices that have a variety of perceived performance or capabilities.The role of the sensory layer is to sense and collect physical events generated in the physical world and related event information data.So,the sensory layer serves as the basis for things or event links and is the most basic technology for achieving the Internet of things.As the basic layer of the development of the Internet of Things,the sensory layer provides certain technologies for establishing low-cost,high-efficiency,and high-sensitivity Internet of things.Based on this,The main work of this dissertation aim at the structure of the sensory layer of the Internet of Things and research and analysis the Internet of Things.The details are as follows:(1)First,it introduces the related knowledges of the Internet of things: the definition,basic features,development process,development status and development trend of the Internet of things;then,the structure of the IOT perception layer is studied and analyzed in view of the components of the IOT perception layer.(2)This paper gives a detailed overview of the concept and main features of the discrete event dynamic system,the logic hierarchy model and the theoretical development,structure,combination and application fields.(3)The DEDS system is considered as a double sub algebra state,and the double sub algebra is discussed and analyzed.In particular,the application of the limit algebra theory to the modeling and function of the computer field is studied and analyzed,and the network analysis method based on the maximal algebra is compared with the analysis method based on the minimal algebra.The advantages and applications of maximum algebra method are discussed.(4)This paper introduces the related concepts and research status of WSN,and analyzes the formalization of Internet of things sensor network security protocols.It also introduces the security of the Internet of things sensor network,and uses the SNIT protocol to model and analyze the Internet of things sensor network.In short,the Internet of things perception layer as the basic level of the development of the Internet of things has important research significance and research value.This paper provides some theoretical support and technical support for establishing a low cost,high efficiency and high sensitivity Internet of things network.
