Research Of6LoWPAN In Internet Of Things Application Based On Multiple Open Source System

Along with the upgrade and continuous development of network technology, perception of science and technology and high performance, a word once emerging "IoT"(Internet of Things) gradually begins opening to the general population. IoT is a kind of extension of Internet technology when products connecting, it’s also regarded as another revolution of science technology after computer revolution and the Internet boom. The will of IoT is to implement all things connect with each other, everything online. The key point is, we could access, perception and control product in any place, at any time. The technology of IoT cannot develop without sensor network. Nodes in network access to Internet realizing the IP is a important part of the technology of IoT. Internet task working group applying IPv6in the IEEE802.15.4, made the6loWPAN protocol, realized the connection between the wireless sensor network and IP network.This paper realized6LoWPAN protocol based on multiple open source operating system applied in the field of environmental monitoring, in this way, We can use the wired or wireless way through sensor collected online equipment of sensitive data, such as temperature, voltage, and control equipment remotely. The main innovation point is to combine with Arduino which is now very popular and Contiki platform, take their advantages, equivalent to a new kind of control system. In order to implement the hardware environment monitoring, this paper’s main work begins with the background of the iot research, analyzes the domestic and international status of the Internet of things technology, and to understand the IP compound networking system architecture and analyzes the advantages of the IPv6protocol in the possibility of IEEE802.15.4protocol on application. Then compared the embedded Internet operating system in the world today, chose the Contiki operating system platform for further research. Based on the platform of Contiki operating system can completely implement6loWPAN protocol and a variety of IETF formulated by the relevant protocol. At last, we achieved the function of61oWpan border router by reaching OpenWRT, completed the6loWPAN based on HTTP and CoAP protocol for online equipments ensor data acquisition and control for the manipulative parts of device.
