  In this paper, we used XBee wireless technology due to the privileges that it
provides in terms of low cost and a high level of security which gives a more
reliable information transfer, penetration avoidance, and unauthorized access,
without any cost in sending and receiving this information. The aim of this
work is to syndicate the XBee wireless technology and global positioning system
(GPS) for a low-cost real-time vehicle tracking system and displaying the
result on Google earth. The overall system involved two main modules, the
displaying module (monitoring station) and the following module (vehicle unit).
The following module consists of microcontroller (Arduino) platform, XBee, and
GPS for navigation purpose. The GPS delivers real-time data about the location
of the vehicle and directs the coordinate to the XBee via the Arduino platform.
The later is incorporated as a connecting buffer between the XBee transmission
unit and the GPS receiver. Receiving the location data of the tracked vehicle
and displaying them on Google earth is the responsibility of the monitoring
station. The designed system has been tested practically in both crowded and
open area environments, the overall system works well and displayed the vehicle
coordinates nevertheless the existence of noise and interference in the vehicle
area and regardless the obstacles like buildings.
