The intemet of things has been paid more and more attention by the government, academe and industry all over the world nowdays. We first analysis the basic concept of Intemet of things, and compare the relationships among the Intemet of Things, Wireless Sensor Network, Internet and the Cyber Physics System. Then, we describe the architecture and technology system of Intemet of Things and propose corresponding models. Furthermore, we analysis the current states and problems of Intemet of Things. FinaLly, for the existing problems of Intemet of things in our country, development proposals are suggested for the future.
