Data prebuffering using sql ce database on real time operation system Windows Mobile 6.0

Main area of interest is in a model of data prebuffering based system enhancement for locating and tracking users of our control system inside the buildings. The developed framework joins the concepts of location and user tracking as an extension for a new information system. The experimental framework prototype uses a WiFi network infrastructure to let a mobile device determine its indoor position. User location is used for data pre-buffering and pushing information from server to user´s PDA. All server data is saved as artifacts (together) with its position information in building. The accessing of prebuffered data on mobile device can highly improve response time needed to view large multimedia data. On mobile device the SQL server CE database is used. Mobile device operate with Windows Mobile 6.0 operation system which is real time. All operations in such mobile clients are deterministic.
