Abstract:
A GPS based tracking system is proposed which keeps track of the location and speed of a vehicle which can be monitored by a mobile phone text messaging system. The system is able to provide real-time text alerts for speed and current location of a vehicle. Particularly, the present location can be locked and the system will alert the owner by sending a text message if the vehicle is moved from the present locked location. In addition, the speed can be locked and an alert can be sent to ownerâ€™s mobile phone if this speed is exceeded.
