Short-range communication technology in the internet of vehicles

In recent years, as an instance of a vehicular ad hoc network, the telematics integrating the utility of telecommunications and informatics has dramatically promoted the development of wireless communications in vehicular environments, intelligent transportation systems, and the automotive electronics industry. Nowadays, IEEE 802.11p and IEEE 1609 family standards are called wireless access in vehicular environments (WAVE) standards, since they are developed to facilitate the provision of wireless access in vehicular environments. The WAVE technology is classified under dedicated short-range communications (DSRC). Several ongoing research projects supported by car manufacturers, electronic industries, governments, and academia have been underway to accelerate the deployment of short-range wireless networks that exploit vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) infrastructure communications based on WAVE. These networks are characterized by rapidly changing topologies and short connection lifetimes, and one of the most important goals of the emerging DSRC-based V2V communication standards is to enable road safety applications that could save thousands of lives.
