Zigbee,6LoWPAN,Z-Wave简介

Zigbee

      Zigbee是基于IEEE802.15.4标准的低功耗个域网协议。根据这个协议规定的技术是一种短距离、低功耗的无线通信技术。这一名称来源于蜜蜂的八字舞，由于蜜蜂(bee)是靠飞翔和“嗡嗡”(zig)地抖动翅膀的“舞蹈”来与同伴传递花粉所在方位信息，也就是说蜜蜂依靠这样的方式构成了群体中的通信网络。其特点是近距离、低复杂度、自组织、低功耗、高数据速率、低成本。主要适合用于自动控制和远程控制领域，可以嵌入各种设备。简而言之，ZigBee就是一种便宜的，低功耗的近距离无线组网通讯技术。

                                            

6LoWPAN

  6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area Networks.6LoWPAN is the name of a working group in the Internet area of the IETF.The 6LoWPAN concept originated from the idea that "the Internet Protocol could and should be applied even to the smallest devices,"^[2] and that low-power devices with limited processing capabilities should be able to participate in the Internet of Things.The 6LoWPAN group has defined encapsulation and header compression mechanisms that allow IPv6 packets to be sent to and received from over IEEE 802.15.4 based networks. IPv4 and IPv6 are the work horses for data delivery for local-area networks, metropolitan area networks, and wide-area networks such as the Internet. Likewise, IEEE 802.15.4 devices provide sensing communication-ability in the wireless domain. The inherent natures of the two networks though, are different.The base specification developed by the 6LoWPAN IETF group is RFC 6282. The problem statement document is RFC 4919,6LoWPAN PHY和MAC层也是基于IEEE802.15.4标准  

                                                                                                         

Z-Wave

     Z-Wave是一种无线通信协议，专门应用在智能家居上，如住宅和轻型商用车远程控制。Z-Wave射频具有低功耗，使得这项技术可以嵌入或改装到家电中。这项技术主要应用在以下几个方面：灯光、住宅远程控制，娱乐系统以及家用电器。Z-Wave PHY和MAC层是基于ITU-T G.9958协议(Short range narrow-band digital radiocommunication transceivers – PHY and MAC layer specifications)
