PDPT framework design is based on the most
commonly used server-client architecture. To
process data the server has online connection to the
information system. Technology data are continually
saved to SQL Server database (Arikan E., Jenq J.,
2007), (Jewett M., Lasker S., Swigart S., 2006).
Figure 2: Old application buffering.
The active presented area was divided to more
partial artefacts. This new modified system is now
implemented to our other projects, where the
position of user is needed. One of these projects is a
Guardian II. This project is for hospitals areas for
patients and physicians monitoring. In such
implemented the new possibilities of biomedical e-
health systems are discovered for increasing of
interactivity. Based on position of patient, the server
can select the nearest physician or nurse to act on
discovered problem. By this way the response on
problem can be reduced and it can help to save more
human life. One of next steps is testing of accessible
technologies for accessing of SQL server buffer and
the selection of better one. In this time the testing of
technologies like LINQ, ADO.NET and the direct
access using SQL queries is being realized.
4 CONCLUSIONS
The main objective of this paper is in the
enhancement of information system for locating and
tracking of users inside a building. It is possible to
locate and track the users inside buildings. In this
paper I have presented the information system
framework that uses and handles location
information and information system functionality.
The indoor location of a mobile user is obtained
through an infrastructure of WiFi access points. This
mechanism measures the quality of the link of
nearby location provider access points to determine
actual user position. User location is used in the core
of server application of PDPT framework to data
prebuffering and pushing information from server to
user’s PDA. Data prebuffering is the most important
technique to reduce time from user request to system
response. It is important to give a high importance to
final optimalization of application.
The experiments show that the location
determination mechanism results with sufficient
quality of the actual location of the user in most
cases. Some minor inaccuracy does not major effect
on PDPT core decision making.
