　　Mesh Networking， the Critical Open Sesame for Smart Lighting Success

　　家庭和小建筑物的业主接受智能技术的好处，如自动光激活和调光，提供更好的舒适性和便利性以及公用事业法案。家庭自动化市场预计将超过160亿美元，由2019。易以最小的中断或昂贵的重装升级，非常可行的一种DIY项目或使用本地安装程序，不需要专家或智能建筑知识，将广泛采用的关键。标准机构已经认识到简化过程，如建立网络和增加新设备的重要性，并引入标准，尽量减少调试和维护所需的技术知识

　　ZigBee®联盟为例，介绍了ZigBee光链路（ZLL）剖面提供了一个标准的关注更入门级智能照明的机遇和比其他公司如ZigBee家庭自动化更容易安装和使用（闸）。所有的执行协调员不调试简化初始网络设置和添加额外的节点。常见的照明设备和控制器的支持，如可调光灯，彩色灯，颜色或场景控制器，而扩展到ZigBee集群库支持行动，如建立场景和控制颜色。在一个可信的协调装置的情况下，通过交换网络关键节点保持与所有的主密钥加密的安全。

　　Like the Home Automation profile， ZLL runs on top of the ZigBee PRO wireless network protocol， which has important strengths for home automation and smart lighting. These include low power consumption， as well as support for peer-to-peer mesh connectivity that enables robust fault-tolerant wireless communication throughout networks that extend over large distances.

　　While low power consumption and the robustness and extended range inherent in mesh networking deliver obvious advantages for smart lighting in homes or offices， another feature that is increasingly expected is the ability to adjust settings using a mobile phone either from within the premises or from a remote location via the Internet. This is not only convenient for users， who tend to carry a smartphone easily to hand， but can also save product vendors the additional overhead of having to build and ship a dedicated controller.
