Indoor Positioning System Using Wi-Fi

At present, there is almost a citizen who has his own vehicle, and the theft occurs in the parking lot, sometimes driving in an unsafe place. Vehicle safety is very necessary for public vehicles. A vehicle tracking and locking system is installed in the vehicle to track in place and lock the vehicle engine. The vehicle uses the global positioning system (GPS) to determine the location and the global system for mobile communications (GSM). These systems need to constantly observe the needs of a moving vehicle and status reports. When the theft is identified, the person in charge sends a short message to the MCU, which then sends a control signal to stop the engine. The authorized person needs to send the password to the controller to restart the vehicle and open the door. It's safer, more reliable, and less costly.
