An automotive navigation system[2],[12] is radio frequency
based wirless-mobile navigation system designed to guide
vehicles in its location using digital map[4] display.
Using the
road/path database, system can give multiple directions to other
locations to reach destination.
Vehicle tracking systems are electronic devices installed in
vehicles to enable vehicle owners or third parties to track the
location of a vehicle.
Most modern vehicle tracking systems now
use GPS[7] modules to allow for easy and accurate location of
the vehicle.
Many systems also combine a communications
component such as cellular or satellite transmitters to
communicate the vehicle's location to a remote user.
Vehicle
information can be viewed on electronic maps using the Internet
or specialized software.
The disadvantage of navigation system
function by GPS is it cannot locate a vehicle which is inside big
campuses like universities, airports, and tunnel [11].
The WiFi
(Wireless Local Area Network) provides the navigation, tracking
function in the big campuses area like universities, airports.
