Abstract

In this paper, we present DGS, a Driving Guidance System based on wireless sensor networks (WSN) which guides a driver to drive a car in safety. The system consists of two sub-systems: SMS (Speed Measurement Sub-system) and WPS (Weather information Providing Sub-system). SMS measures the speed of a car and captures the image of the speeding car using a speed camera. WPS provides weather information including the road conditions (icy, wet, etc.) via VMS or a telematics terminal. The paper describes the overall system architecture of DGS from the hardware platform to the application software in the view point of a WSN. We implemented the WSN based SMS of DGS from hardware to application software. The experimental results show that the accuracy of speed measurement is over 99% at 80kmph and the predicted battery life-time using measured current profiles is about 3 years. We also discuss the lessons acquired from the real-life experiments we performed. We believe that the lessons can be useful in other WSN applications as well as in typical telematics applications.
