Harnessing Wireless LAN Communication for Scalable Indoor Localization and Tracking
Sprache des Titels:
Localization of people is an integral aspect of mobile computing research that has been inves-tigated primarily on the basis of radio or sound sensor technologies such as Bluetooth, WLAN or ultrasound. Due to the physical behavior of these carrier technologies in different environments, a principal distinction between outdoor and indoor localization has evolved. As an outstanding example of applied localization technologies, the Global Positioning System demonstrates the feasibility of a client-based solution to the outdoor localization problem on a global scale. For indoor spaces on the other hand, no convincing counterpart has emerged so far. The problem of localizing people indoors is still considered a matter of intense research.
Basically, two approaches exist for determining the user?s location indoors. The client-based variant assumes that sensor functionality is integrated in the mobile device of the user. The infrastructure-based solution uses sensors embedded in the environment. Recently, client-based WLAN localization has been the prevalent choice of technology for both mobile application research and the consumer market mainly because of the high availability of WLAN communication hardware.
