Abstract: The things is object connected to Internet of Things(IoT)，and it's attributes determine IoT characteristics and research methods. Analysis of the main attributes of things indicate the things is man, service, substance and product, kind of representative agent IoT main features are self-feedback architecture, 3C, security, complex networks, complex ecosystem, and IoT complex ecosystem theory model is composed of TSESOI(Time, Space, Energy, Structure, Order, Information). Analysis of the relationship between basic concepts and network applications gives a theoretical founlotion architecture related to IoT.

Key words: Internet of things, Perception, Agent, Complex network, Network science
