【摘要】 普适计算将是未来的主流计算模式,物联网是互联网的下一代发展形态.物联网的出现使普适计算的计算环境发生变化:①物体的普遍联网,使普适计算的环境进一步拓展,从而构成了更加复杂的计算物理空间.而对应信息空间如何组织,是一个值得研究的问题;②物联网为普适计算中的服务迁移提出了更高的普遍适应要求,并促进了对普适计算进一步研究和发展,推动普适计算成为物联网的基本计算模型.本文提出一种新型网络应用架构ASR.ASR重点解决了两个问题:①面向广域物联网中的普适计算服务迁移技术问题,提出了计算区域网模型,使计算服务可以在广域物联网中针对不同的"物联网"环境执行,而不是传统的在个体计算环境中执行.②提出了以"参照执行"为核心的计算框架模型,进行了面向物联网的服务普适性研究,可以使计算服务更加适应于不同的物联网环境.更多还原

【Abstract】 Pervasive computing will be the mainstream computing model in future,and Internet of Things is the next generation of Internet.The emergence the Internet of Things changes the environment of pervasive Computing:?Objects in general networking expands pervasive computing environment, and thus constitute a more complex calculation physical space,and how to organize the corresponding information space is a problem worthy of study.?Internet of Things put forward higher requirements to pervasive computing,promote further research on the development of pervasive computing, and drive pervasive computing to the basic computational model.This paper proposes a new network application architecture ASR.ASR focused on solving the two problems:①Things for wide-area pervasive computing services in the migration of technical problems,made a model of computing area network,so that services can be calculated in the wide area of things for different ’Internet of Things’ environmental performance,rather than the traditional calculation in the individual execution environment.②Put forward a "reference implementation" as the core framework of model calculations,and carry out for the things of universal services,make computing services to adapt to different environments.更多还原
