Mesh Networking， the Critical Open Sesame for Smart Lighting Success

　　家庭和小建筑物的業(yè)主接受智能技術(shù)的好處，如自動光激活和調(diào)光，提供更好的舒適性和便利性以及公用事業(yè)法案。家庭自動化市場預(yù)計將超過160億美元，由2019。易以最小的中斷或昂貴的重裝升級，非常可行的一種DIY項(xiàng)目或使用本地安裝程序，不需要專家或智能建筑知識，將廣泛采用的關(guān)鍵。標(biāo)準(zhǔn)機(jī)構(gòu)已經(jīng)認(rèn)識到簡化過程，如建立網(wǎng)絡(luò)和增加新設(shè)備的重要性，并引入標(biāo)準(zhǔn)，盡量減少調(diào)試和維護(hù)所需的技術(shù)知識

　　ZigBee?聯(lián)盟為例，介紹了ZigBee光鏈路（ZLL）剖面提供了一個標(biāo)準(zhǔn)的關(guān)注更入門級智能照明的機(jī)遇和比其他公司如ZigBee家庭自動化更容易安裝和使用（閘）。所有的執(zhí)行協(xié)調(diào)員不調(diào)試簡化初始網(wǎng)絡(luò)設(shè)置和添加額外的節(jié)點(diǎn)。常見的照明設(shè)備和控制器的支持，如可調(diào)光燈，彩色燈，顏色或場景控制器，而擴(kuò)展到ZigBee集群庫支持行動，如建立場景和控制顏色。在一個可信的協(xié)調(diào)裝置的情況下，通過交換網(wǎng)絡(luò)關(guān)鍵節(jié)點(diǎn)保持與所有的主密鑰加密的安全。

　　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.
