Abstract

This paper describes the issues involved in performing location tracking in a library environment using existing wireless LAN infrastructure and personal digital assistants. Limitations on computation power and operating systems support are considered in the experiment design and four mainstream location estimation algorithms: center of gravity, triangulation, smallest M-vertex polygon and fingerprinting, are being compared to facilitate location-aware computing.
