我们已经见证了固定互联网的出现，今天几乎每台计算机都连接在一起;我们目前正在见证移动的互联网的出现，智能手机、平板电脑和上网本呈指数级爆炸式增长。然而，与物联网（IoT）的预期出现相比，这两者都将相形见绌，在物联网中，日常物品能够连接到互联网，推特或被查询。虽然对世界各地的经济和社会的影响是无可争议的，促进这种无处不在的连接的技术一直在努力，直到最近才开始形成。为此，本文及时介绍了业界认为符合电源效率，可靠性和互联网连接的重要标准的无线通信堆栈。工业应用已经成为该协议栈的早期采用者，该协议栈已成为事实上的标准，从而引导了早期的物联网开发，已经部署了数千个无线节点。通过本文和新兴行业联盟的验证，我们相信，使用IEEE 802.15.4和IETF工作组的最新发展的标准化方法是唯一的前进方向。我们介绍并涉及功率高效的IEEE 802.15.4-2006 PHY层、功率节省且可靠的IEEE 802.15.4e MAC层、实现通用互联网连接的IETF 6LoW-PAN适配层、实现可用性的IETF ROLL路由协议的关键实施例，最后，IETF CoAP实现了互联网应用的无缝传输和支持。本工作中提出的协议栈收敛于以下标准化符号：ISO/OSI和TCP/IP协议栈。几年前似乎不可能的事情，即，鉴于物联网网络的极端限制，构建一个定义明确、符合标准和符合互联网的堆栈正开始成为现实。
We have witnessed the Fixed Internet emerging with virtually every computer being connected today; we are currently witnessing the emergence of the Mobile Internet with the exponential explosion of smart phones, tablets and net-books. However, both will be dwarfed by the anticipated emergence of the Internet of Things (IoT), in which everyday objects are able to connect to the Internet, tweet or be queried. Whilst the impact onto economies and societies around the world is undisputed, the technologies facilitating such a ubiquitous connectivity have struggled so far and only recently commenced to take shape.To this end, this paper introduces in a timely manner and for the first time the wireless communications stack the industry believes to meet the important criteria of power-efficiency, reliability and Internet connectivity. Industrial applications have been the early adopters of this stack, which has become the defacto standard, thereby bootstrapping early IoT developments with already thousands of wireless nodes deployed.Corroborated throughout this paper and by emerging industry alliances, we believe that a standardized approach, using latest developments in the IEEE 802.15.4 and IETF working groups, is the only way forward. We introduce and relate key embodiments of the power-efficient IEEE 802.15.4-2006 PHY layer, the power-saving and reliable IEEE 802.15.4e MAC layer, the IETF 6LoW-PAN adaptation layer enabling universal Internet connectivity, the IETF ROLL routing protocol enabling availability, and finally the IETF CoAP enabling seamless transport and support of Internet applications.The protocol stack proposed in the present work converges towards the standardized notations of the ISO/OSI and TCP/IP stacks. What thus seemed impossible some years back, i.e., building a clearly defined, standards-compliant and Internet-compliant stack given the extreme restrictions of IoT networks, is commencing to become reality.
