摘　　要：近年来,物联网的发展受到了高度重视,学术界、工业界及政府对物联网的发展给予极大关注.物联网被认为是可以将数以亿计的物理对象连接起来,通过信息技术进行监测、分析和控制的网络,在延伸人类的感知控制能力方面潜力巨大.大量物联网研究工作已经开展,许多物联网示范系统也被开发,并取得了显著应用效果.但同时,物联网当前的发展也面临着一些根本性的问题:物联网有什么特殊需求必须满足?当前物联网技术处于什么阶段?物联网的发展方向在哪里?这些问题值得探讨.本文回顾了互联网发展的历程,并根据互联网发展经验,分析物联网的现状,提出物联网当前处于"物-机"相连的局部小规模物网阶段,其发展方向应是相连众多小规模"物网"的开放大网——"物联网".基于这一思路,提出称之为WInternet的物联网设计,并介绍了其总体架构、工作模式和协议体系,同时也探讨了若干其他值得进一步研究的问题.In recently years, Internet of things （IoT） has attracted great attentions from academic, industry, and the government. IoT is considered to be a network that can connect billions of physical objects together, and has great potential in extending human beings capability in monitoring, analyzing, and controlling the physical space using cyber technologies. Extensive IoT research has been done. Large number of IoT systems have been built and applied successfully. However, the development of loT is facing several fundamental issues, such as what are the characteristic requirements of loT？ What is the current development stage of loT, and what is the future direction？ These are questions need further investigation. In this paper, we review the development history of Internet and summarize the lessons we learned from this development. Then we analyze the current status of loT, and argue that most of the current IoT systems are ＂net o~ things＂, i. e. , small scale networks connecting physical physical objects. The future of IoT should be ＂Internet of Things＂, i. e. , inter-connected, large scale, and open network. With this judgment, we propose a novel IoT architecture, named WInternet, and disuse its design principals, network topology, connection scheme, protocol stack, as well the open issues in IoT and WInternet development.
