On Internet and Internet of things

Abstract

Based on analysis of development history and application environment changes of Internet,this paper provided a comprehensive discussion on incentive,connotation,organization,and some key issues of Internet of Things(IoT).On basis of analysis of typical definition of IoT,the author believed that the full range of information interoperability ITU to IoT as an Internet platform in application areas of human,machine,and intelligent physical objects(SPO) and next generation Internet applications generalization of Pervasive Computing(Ubiquitous Computing) concept is a more reasonable broad definition of IoT.Based on this definition,the author analyzed basic organization of IoT,which consisted of interconnected multiple Customer Premises Network(CPN) via backbone Subnetworks,and examined two types of components of SPO-CPN and their supporting techniques.It was also pointed out that introduction of SPO has little impact on Internet technology,except on access part of CPN of application systems.The author disagreed on definition of IoT in narrow sense given by European communities,which restricted IoT to Internet of interconnecting physical objects,and pointed out their models and architectures of IoT are essentially those of network application systems.
