物联网架构和智能信息处理理论与关键技术

Theory and Key Technologies of Architecture and Intelligent Information Processing for Internet of Things

物联网(Internet of Things,IoT)是一种通过各种接入技术将海量电子设备与互联网进行互联的大规模虚拟网络,包括RFID、传感器以及执行器的电子设备通过互联网互联互通,将异构信息汇聚后共同完成某项特定的任务。为了解决物联网规模化运用中的关键技术,首先探讨了物联网与这些网络的区别,给出了物联网的定义、特征以及参考架构。同时,创新性地提出了区域服务器的概念,并通过本体论知识表达等方法的运用解决了物联网中的"信息孤岛"难题。智能信息处理是物联网的核心内容之一,而物联网的知识表达与情景感知等相关技术是物联网智能信息处理的核心内容。据此,着重分析研究了智能信息处理的信息空间定义、信息量化方法以及信息处理各阶段的主要问题及相应的解决办法。

Internet of Things（IoT） is a virtual network which is dedicated to combine the Internet and a huge number of things together and those things are connected to the Internet via various technologies,e.g.,wired or wireless technologies.By connecting to the Internet,things,e.g.,RFID,sensors or actuators,could communicate with each other.Firstly,this paper introduced the characteristics,network architecture and the difference among IoT and other networks,e.g.,wireless sensor networks and RFID.To achieve the target of large-scale application,we proposed a general network architecture for IoT.Meanwhile,the concept of Regional Server was presented firstly in the proposed architecture to address the ＂Information Isolated Island＂ problem.Then,this paper claimed that semantic interoperability,knowledge presentation and context-ware technology are key technologies for IoT.Accordingly,this paper deeply investigated the key problems of intelligent information processing,e.g.definition of information spaces,quality of information and information processing technologies,in an extensive way.
