随着信息技术的飞速发展,无线传感器网络正成为传感器领域内一个新兴的研究方向,它是一种全新的信息获取和处理技术。同时,随着无线传感器网络技术的成熟,普适计算电渐渐成为现实。通过普适计算,人们可以随时随地获得所需要的各种信息。这些技术的应用,将给人们的生活带来前所未有的便利。文中以此为研究背景,分别介绍了无线传感器网络的起源、发展和特色,以及普适计算的出现、概念和具体构建。
With the magic development of information technology, wireless sensor networks ,are becoming a new research field. It is a novel technology about acquiring and processing information. And with the maturity of the wireless sensor networks, pervasive computing is also becoming a reality, which means that to provide people with any interested information whenever and wherever. With the application of these technologies, it will bring people a lot unprecedented convenienee. With these researches and applications background, this thesis separately describes the origin, development and features of wireless sensor networks, the emergence, idea and implementation of the pervasive computing.
