Wireless Campus LBS: A Test Bed for WiFi Positioning and Location Based Services

摘要

The Wireless Campus LBS project is designed to provide a test bed for location-based services (LBS) research, and it is a valued service for the University of Twente (UT) campus community. Initiated in early 2005, the project's research team is comprised of members from the University of Twente Computer Architecture Design and Test for Embedded Systems group, the UT department of Information Technology, Library and Education, and the International Institute for Geo-lnformation Science and Earth Observation. The research has focused on Wireless LAN positioning techniques and contextually aware data management systems for ubiquitous computing. The system delivers mapping information for LBS and mobile applications through the use of adaptive, cartography-aware database objects. In this paper, we describe the theoretical background of LBS and positioning services in location-aware GIS and database technology, the University of Twente Wireless Campus, and the prototype we developed for providing positioning and location-based services using that Wireless Campus environment.
