Sensing Technologies in Ubiquitous Network Environment : From Stand-alone Intelligent Sensing to Knowledge-Shared Network Sensing

Real world consists of various kinds of natural and man-made objects, which are changing, moving, and interacting with each other dynamically. Capturing all these objects widely, continuously, and accurately is the rapidly growing subjects in the sensing technology. In order to use those vast information in the computerized network environment as precious resources, and make the best use of the corresponding physical objects as sustainable resources, we will show in this article how the ubiquitous sensing and networkin systems can be developed based on a tight coupling of sensing and wireless communication technologies, and based on a tight coupling of objects in the real world and information in somewhere in the network via a ubiquitous, automatic identification tag system.
