Design of 6LoWPAN border router based on multiple open source system

Abstract

Based on the open source system of OpenWrt,it develops application socket-support,and ports the 6LoWPAN/RPL border router(6LBR) to the OpenWrt. It Choses TL-WR703N SoC and CC1310DK as the core handware platforms, and relys on Contiki,6LBR and OpenWrt, to design a 6LoWPAN border router. Meantime,it uses lowpower CC1310 chips produced by TI company to design two 6LoWPAN sub nodes，and buids a testing network of Internet of Things, including a PC, two 6LoWPAN nodes and a 6LoWPAN border router. The result shows that PC terminal can use CoAP protocol to realize the data acquisition and control of the 6LoWPAN node.This 6LoWPAN border router can be applied to some seenarios such as industrial control, environmmental monitoring, smart home and so on, and it has the certain application value.
