Vehicular Ad Hoc Networks

Abstract

Vehicular Ad Hoc Networks(VANETs) are computer networks of moving nodes attached to vehicles. Theyalso include stationary infrastructure elements. This use of wireless local area network technology is becoming necessity and will grow rapidly in the near future. There is a wide range of VANET and associated Dedicated Short Range Communications (DSRC)applications. It starts fromsimple cases likeactive safety systems for driving, traffic information and collision warning, to more comprehensive Intelligent Transport Systems (ITS). Step up from simple driver assistance will be the complete takeover of the vehicle control. Finally, VANETs will support auto driver algorithms and applications for unmanned ground vehicles (UGVs). The aim of this paper is to present an overview of the technology, standards and problems, with some proposals for the quick start with the most necessary applications and for the future research.
