Fast-response inter-vehicle communications
Keywords: ITS, inter-vehicle communications, safe driving, media access control (MAC), CSMA, CDMA Safe driving support is one of the most attractive and important applications of an inter-vehicle communication systems.
Real-time and reliable exchange of status information on such as vehicle location, speed, sudden braking etc., among vehicles, is a key to offering prompt warnings to drivers in order to avoid fatal traffic accidents. We have proposed a novel media access control (MAC) scheme based on code division multiple access (CDMA) technology, which offers fast response and high packet delivery ratio to meet the above requirements. This paper introduces the proposed scheme, performance evaluation by simulation, and prototyping for field experiment. It also mentions future studies.
