Study on the Architecture and Key Technologies for Internet of Things

Internet of Things(IoT) combines sensor technology,embedded computing,Internet and wireless communication technology,distributed information processing technology,and has broad application prospects.Therefore,the revolution of the Internet of Things(IoT) has attracted highly attention of domestic and foreign government,academia and industry.There are still many open issues in the definition,architecture and key technologies of IoT.In this paper,firstly,based on analysis of existing literatures of IoT,the basic concept of IoT is dis-cussed from the view point of the architecture and key technology.Five essential factors which the IoT should have are summarized.Sec-ondly,the architecture is further proposed.its structure and functions are described.Thirdly,the key technologies of IoT are analyzed,in-cluding recognition technology,sensing technology,network technology and smart technology.Finally,this paper gives some suggestions of IoT development.
