Abstract:
The wireless communication technologies enabled vehicles on a highway to communicate, in order to share state information and information to avoid potential collision. This paper discusses a protocol which avoids vehicle accidents. The vehicle state information is being obtained using ultrasonic sensors, to predict potential accident and accordingly the speed of the vehicle is reduced using ARM processor (Advanced RISC Machines). This protocol provides warning message when the safety distance is reduces than the safety limit. Here, the car will be equipped with an ultrasonic sensor which will continuously track for any obstacles from the front side. If the obstacle is detected then the µC will continuously compare the distance given by the ultrasonic sensor. If distance goes on reducing indicating that the front car is coming closer to the current car then the microcontroller will start applying brakes until the distance is within safe limit.
