Abstract: Internet of Things(IoT) is a virtual network which is dedicated to combine the Internet and a huge number of things together and those things arc connected to the Internet via various technologies, e. g. , wired or wireless technologies. By connecting to the Internet, things, e. g. , RFID, sensors or actuators, could communicate with each other. First1y, this paper introduced the characteristics, network architecture and the difference among Ioh and other networks, e.g. , wireless sensor networks and RFID. To achieve the target of large-scale application, we proposed a general network architecture for IoT. Meanwhile, the concept of Regional Server was presented firstly in the proposed architecture to address the "Information Isolated Island" problem. Then, this paper claimed that semantic interoperability, knowledge presentation and context-ware technology arc key technologies for Ioh. Accordingly, this paper deeply investigated the key problems of intelligent information processing, e. g. definition of information spaces, duality of information and information processing technologies,in an extensive way.
