Design And Implementation Of The Wireless Internet Of Things System Based On The6LoWPAN Technology

With the development of computer networks, more and more devices need to access thenetwork. So the Internet of Things has become a hot research at home and abroad. Thedevelopment of the Internet of Things can not be separated with the sensor network. Assign IPaddresses to wireless sensor networks, and access to the internet has become an importantbranch of the internet of things. In order to achieve a seamless connection between wirelesssensor networks and IP networks.6LoWPAN working group of the Internet Engineering TaskForce is committed to IPv6applications on top of the IEEE802.15.4.The focus of the research is to design and implement a Internet of Things applicationplatform which base on6LoWPAN technology. Platform in the hardware and software to useas much as possible to meet the versatility, scalability principle, so as to provide a platform toadapt to the more scenarios.The hardware is the production of Smeshlink, include MX231CC wireless node and theMX-USBStick wireless gateway, and JTAG download. The software uses the integrateddevelopment of ContikiStudio environment (GCC AVRStudio).References of Internet of Things application model, raising a network architecture of theInternet of Things application platform which based on6LoWPAN, hardware and softwareimplementation is divided into four main parts: the sensor nodes, gateways, web configurationinterface and database server.The paper described the basic concept of the Internet of Things, research status anddevelopment trends, and in-depth study of the basic technology of IPv6and6LoWPAN.Reference6LoWPAN release of the draft agreement, carried out a detailed study on the the6LoWPAN core technology. Combined with the the Contiki system of characteristics, designand realization a based Contiki6LoWPAN wireless Internet of Things, analysis of the overallprotocol architecture of the network system, elaborated the system core technology andprogramming. Finally, test the system to achieve in actual. The results show that the systemcan work properly, communicate via IPv6, the web interface to view real-time and historicalmonitoring data. It also can be achieved through the expansion board, remote control function on the lamp. And in accordance with the actual needs of future, the corresponding functioncan be expanded.
