Abstract

New types of complex mobile devices can operate full scale applications with same comfort as their desktop equivalents only with several limitations. One of them is insufficient transfer speed on wireless connectivity in case of downloading the large multimedia files. Main area of paper is in a model of a system enhancement for locating and tracking users of a mobile information system. User location is used for data prebuffering and pushing information from server to user’s PDA. All server data is saved as artifacts along with its position information in building or larger area environment. The new partial prebuffering techniques is designed and pretested. The accessing of prebuffered data on mobile device can highly improve response time needed to view large multimedia data. This fact can help with design of new full scale applications for mobile devices.
