Abstract: hhe Internet of things is the hot spot of current research, which will bring out a trillion level information industry. The architecture about the Internet of things is divergent since the occurrence of IoT. There are mainly three layer, four layer, five layer architecture, etc. In this paper, various architectures of Ioh were studied. The advantages and disadvantages of its performance and suitable field of its application were analyzed and compared. Meanwhile, the serviccoriented architecture of Io T was put forward in order to provide the reference model for the various application of IoT.

Key words: Service-oriented, Cloud processing, Internet of Thing, Architecture
