基于对物联网概念的理解,文章介绍了物联网的特征,特别是其底层感知信息的时空特性和局部实时交互性,以及从对物理世界的感知、感知信息的传输和处理、对物理空间的反馈控制的开放式循环过程。基于云计算到海计算再到云海结合,从信息存储和处理的角度出发,文章探讨了物联网承载和处理巨海量信息的方式和结构,以及物联网体系结构需要考虑的问题,如开放性式循环结构和智能终端。
The most salient features of IoT are its spacial and temporal perception of information and the local real-time interaction,the open-cycle of perceiving,transmitting,and processing perceived information,and feedback control of the physical world.This paper considers sea computing and the combination of sea and cloud computing in discussing the architecture needed to bear and process mass information in IoT.Some proposals on the design of open-cycle structure and intelligent terminals are also made.
