Intelligent Prebuffering Using Position Oriented Database for Mobile Devices

Paper describes a concept of PDPT Framework with main focus on Position Oriented Database on server and mobile devices. Also the problem of low data throughput on mobile devices is described as a main, which can be solved by PDPT framework. Some interested details from development of Position Oriented Database on mobile devices equipped with Windows Mobile operating system are also showed as a program code in C# language and a data-base structure at server and mobile side. Localization and user tracking is described only as a necessary condition for prebuffering realization because the PDPT Core maces a decision when and which artifact (large data files) need to be prebuffered. Every artifact is stored along with its position information (e.g. in building or larger area environment). The accessing of prebuffered data artifacts on mobile device improve the download speed and response time needed to view large multimedia data. The conditions for real sticking in corporate areas are discussed at the end of paper along with problems that must be solved before stocking.
