LED intelligent lighting system based on 6LoWPAN

Nowadays, the LED industry has witnessed an ever-growing development. LED intelligent lighting system, which is highly-efficient, environment-friendly, intelligent, and user-friendly, has become a new trend in the lighting industry. Formed by LED lamps, wireless sensor network needs a large amount of nodes. To realize its IP, a large number of IP addresses are needed. But the wireless sensor network is not compatible with IPv6, which contains lots of address resources. The design and implementation of IPv6 node based on the protocol of 6LoWPAN will be first illustrated in this paper. IPv6node uses CC2530 as the hardware core, and combines with LED constant-current drive circuit. The software part applies Contiki, an open-source operating system, adopts ZigBee Cluster Library as the application, blends uIPv6 protocol stack and 6LoWPAN technology to achieve the compatibility between IPv6 and IEEE 802.15.4, and connects the IPv6 nodes by using RPL router protocol so as to form a wireless lighting network based on IPv6. Then the design of the gateway node used to convert IPv4 protocol and IPv6 protocol will be introduced in the paper. It applies CC2538 microcontroller and make possible the frequent transceiver of wireless radio. Then the paper introduces the design and implementation of network communication module and the interface and function module on the Android interface through the appliance of the IPv4 control node.
