4 CONCLUSIONS
I am focused on the real usage of the developed
PDPT Framework on a wide range of wireless
mobile devices and its main issue at increased data
transfer. For testing purpose, five mobile devices
were selected with different hardware and software
capabilities. The high success rate found in the test
data surpassed our expectations. This rate varies
from 84 to 96 %.
The PDPT prebuffering techniques can improve
the using of medium or large artifacts on wireless
mobile devices connected to information systems.
The localization part of PDPT framework is
currently used in another project of biotelemetrical
system for home care named Guardian II to make a
patient’s life safer. Another utilization of PDPT
consists in use of others wireless networks like BT,
GSM/UMTS, WiMAX, or in GPS. This idea can be
used inside the information systems like botanical or
zoological gardens where the GPS navigation can be
used in outdoor. The BT and GSM data collecting
and processing is described in this article along with
sample code. Some improvements of Locator
module or Artifact Manager are described as well as
improved architecture of PDPT server database. The
larger area of PDPT utilization can improve
importance of PDPT Framework in wireless mobile
systems.
