Concept of Vehicle-To-Vehicle Communication

In recent years, as an instance of vehicular ad-hoc network, the telematics integrating the utility of telecommunications and informatics has dramatically promoted the development of wireless communications in vehicular environment, intelligent transportation system, and automotive electronics industry. The further extension of WAVE (Wireless Access in Vehicular Environments) technology is dedicated short range communication (DSRC). These networks are characterized by rapidly changing topologies and shorter connection lifetime, and one of the most essential goals of the emerging DSRC based V2V communication standards is to enable road safety applications that can save thousands of lives. Safety-related applications are primarily geared toward avoiding the risk of car accidents such as cooperative collision warning, lane change, emergency vehicle approaching warning, pre-crash sensing, traffic violation warning.
