There is a drastic increase in the number of crimes involving vehicle theft. This can be avoided by using Real-time anti-theft and tracking mechanism using GSM and GPS. In the current scenario, it takes a minimum of two days to find the lost or the stolen vehicle. Vehicle tracking mechanism alerts the owner or the user of the vehicle with the message at the time of theft occurred. Moreover, this mechanism helps to find the location of the theft vehicle by using GSM and GPS at any time and also stores the message by the application in the mobile. Vehicle tracking mechanism helps to prevent and reduce the theft of vehicles. Further, these types of devices are less expensive and also affordable for all vehicle owners. The ability to track vehicles is useful in many applications including the security of personal vehicles, public transportation systems, School buses, and others. Therefore, the development of vehicle tracking system using the Global Positioning System (GPS) and Global System for Mobile Communications (GSM) modem is with the aim of enabling users to locate their vehicles with ease and in a useful manner. The system will provide users with the capability to track vehicle remotely through the mobile network.
