基于使用IPv6的低功耗无线个人局域网的无线传感网在智慧路灯中的应用

Implementation of IPv6 over low power wireless personal area network based on wireless sensor network in smart lighting

针对现有的采用电力载波通信(PLC)技术的智慧路灯系统中存在系统结构复杂、兼容性与扩展性差、开发部署周期长和安全性与抗干扰性低的问题,提出了一种基于IPv6的低功耗无线个人局域网(6LoWPAN)的智慧路灯系统。将6LoWPAN应用在对基于PLC的智慧路灯系统的改造中,把原有的PLC节点改成6LoWPAN无线节点,把集中控制器改造为边界路由器,并在应用层上采用了受限应用协议(CoAP)和智能物体网际协议(IPSO)应用框架。通过与基于PLC的智慧路灯进行对比,结果表明采用6LoWPAN无线网络的智慧路灯系统结构简化、兼容性与扩展性高、系统开发部署周期缩短一半以上并且网络安全性和抗干扰性较高。

Concerning the disadvantages such as the complexity of the system structure, low compatibility and expansibility, time consuming in development and deployment, low security and anti-interference in the smart lighting system based on Power Line Communication （PLC）, a new smart lighting system based on IPv6 over Low power Wireless Personal Area Network （6LoWPAN） was proposed in this paper. An example of implementing 6LoWPAN in smart lighting system by replacing PLC was presented, the PLC nodes were replaced by 6LoWPAN nodes, the central controller was replaced by border router, and the Constrained Application Protocol （CoAP） and Interuet Protocol for Smart Objects （IPSO） application framework was applied in the application layer. Compared with the smart lighting system based on PLC, the new smart lighting system with 6LoWPAN technology is simpler in system architecture, it has higher compatibility and expansibility, the development and deployment time is reduced more than 50%, the network security and anti-interference is better.
