Specifications of APIs for exchanging information based on ITS dedicated communication

Conversion technology between IT(Information Technology) and automotive technics creates the new industry of ITS (Intelligent Transport systems) and the new paradigm in electronics, communication and traffic fields. Specially, Vehicular communication in ITS field is one of the most important technologies necessary to connect among driver, vehicle and provider to provide quality services. Solutions for vehicular communication based on IEEE 802.11 are described in IEEE 802.11p. IEEE 802.11p WAVE (Wireless Access in the Vehicular Environment) defines amendments to IEEE 802.11 that are necessary to support ITS applications. In Korea, V2V (Vehicle-to-Vehicle) and V2I (Vehicle-to-Infrastructure) communication systems called VMC (Vehicle Multi-hop Communication) are being developed by the Electronics and Telecommunications Research Institute. In this paper, we define the API(Application Protocol Interface) and communication sequence to provide the quality services about the reliability data exchange based on VMC.
