简介：分布式的研究与学术gigabits开的网络实验室(龙实验室)是为与基于用三的同盟网络，层遮蔽结构的下一代因特网(NGI)有关的研究目的唯一的试验台。作为NGI的必要部分，与事情(IoT)的因特网有关的研究设备应该在龙实验室站台上被使用。这篇论文建议一条途径到由集成在龙实验室和IoT之间的云结构的每层集成IoT设备到同盟网络。这项研究活动扩大龙实验室的使用，做IoT和在同盟网络工作很好的无线传感器网络(WSN)设备。它也是为三层云结构的foundational研究，它能为另外的相关研究被再使用。最后，它为IoT因特网协议版本6完成准备工作(IPv6)设备在龙实验室研究，它为NGI是必要的。
