Internet of Things:Summarize on Concepts,Architecture and Key Technology Problem

Internet of things is closely related to numerous fields.We first analyze basic concepts and features of Internet of things,and compare the relationships among Internet of things,the ubiquitous network,machine to machine,and the cyber physics system.Then,we introduce the ubiquitous sensor network(USN) architecture designed by the International Telecommunication Union,and present research proposals for Internet of things architecture.Furthermore,we summarize the key technologies of Internet of things and propose the model of Internet of things technology system.Finally,the status of standardization is concluded and several development proposals are suggested for Internet of things.
