Research On The Framework Of The Internet Of Things

Internet of Things had attracted wide attention as a hot topic gradually with the rapidly development of the technology of the RFID, technology of the Internet, Wireless communication technology, Wireless sensor and so on. The research and application-related fields had more and more attention by many other countries. Now, Wireless communication technology obtains the body’s indentifying information and sensor information through with implanted with microchips into the various objects and connects to the Internet.There are four basic layers in the Internet of Things, the Perception layer, the Transmission layer, the Operating layer and the Application layer. The issue has explored the basic form of the Framework of Internet of Things by the some related technologies, such as the computer technology, Network communication technology, Wireless sensor, indentifying technology in the four layers.Besides technologies mentioned above, the core technology is the development of the middleware. The middleware is connected with the underlying device and the application layer. The middleware can masked the obstruction come from the different of the underlying hardware. The middleware will provide a stable development environment for users. The pros and cons of the middleware can affect the function of internet of things.In recent years, the standard of Coding, Identification and Connector has improved steadily because of the development of the RFID indentifying. However, Wireless sensor network has shortage in the high-performance and low-consumption module design. Therefore the issue has designed and completed a wireless sensor network system which is composed of middleware and several wireless intelligent sensor nodes.The issue has two parts, one part focuses on the Framework of Internet of Things and some other relayed technologies, the other aims at the introduction of the design of a low-power Wireless sensor network. In the last of the issue, some problems and their improving work will be put forward.
