【摘要】 提出了一个以信息为中心的物联网互联框架——GlobeSen,实现传感器网络与互联网的高效互联。首先面向无线传感器节点这类弱网元,结合感知数据的时空特性,设计了一套以信息为中心传感器网络协议NDNs,主要包括感知数据命名方法、基于时空关系的数据匹配方法、路由转发方法和协作式的缓存策略。进而设计了一个运行在网关的协议转换机制NDNt,实现NDNs和互联网上运行的NDNx之间的互通。使用TelosB无线传感器节点和ARM开发板搭建了一套原型系统,并在实地环境中进行了部署,通过一系列实验对上述设计进行了验证。更多还原

【Abstract】 Interconnection framework of information-centric IoT: GlobeSen was proposed, which implemented the efficient interconnection of sensor networks and Internet. According to the characteristic of weak network elements, such as wireless sensor nodes, and the spatio-temporal relationship of sensory data, an information-centric network protocol for sensor networks NDNs was designed. Then, a protocol translation mechanism in the gateway was designed to interconnect NDNs and NDNx that running in Internet. A prototype by using the Telos B wireless sensor node and ARM board was implemented, and the proposed design by deploying the prototype in the environment was evaluated.更多还原
