Evaluation of Various Forms of DSRC System- A Review

Wireless communication is the fastest growing segment of communication industry. It has captured the attention of media and the imagination of public. There are many new applications emerging in the wireless communication including automated highways and factories, smart homes and appliances, remote telemedicine. So the growth of wireless systems coupled with the proliferation of laptop and palmtop computers as standalone systems and as part of the larger networking infrastructure. Vehicle safety wireless communications are emerging due to the occurrence of many accidents when distant objects or roadway impediments are not detected quickly. To avoid these accidents, long range safety systems are needed with real-time detection capability and without requiring a line-of-sight view by the driver or the sensor. Early detection of intersections is required for obstacle location around blind corners and dynamic awareness of approaching vehicles on intersecting roadways. So this article discusses the vehicle safety by the communications-based active safety systems research called Dedicated Short Range Communications (DSRC) used in various forms available in wireless vehicle safety systems.
