普适计算中的室内位置感知

Indoor Location-aware of Ubiquitous Computing

随着计算模式从主机计算和桌面计算逐步向普适计算过渡,上下文感知计算是普适计算的核心研究内容,而位置感知计算在上下文感知计算研究中又具有极其重要的地位。该文综述了多种重要的室内位置感知技术,并结合作者在三维位置定位方面的研究成果介绍了各种位置感知方法,最后对位置感知模型的一般情况进行了深入探讨。

Determining physical location of indoor objects is one of the key issues in development of context-aware applications in ubiquitous computing environment. This is mainly because context information obtained from sensor network is meaningful only when the physical location of context information source is determined. This paper surveys some important indoor locating technologies, and introduces several location-aware methods combining with the author＇s preliminarily research results. A general location-aware framework is discussed elaborately at last.
