Recent research efforts of academia, automotive industry and transportation sector point to Intelligent Transportation Systems as a key technology for improving road safety, traffic efficiency and comfort driving.
Vehicular Ad Hoc Networks (VANETs) have significant potential to enable applications for traffic safety efficiency transportation and sustainable mobility. The dissemination methods and routing mechanisms play
an essential role in the design and characterization of vehicular applications. This article provides an
overview of vehicular ad hoc networks; we describe the fundamental concepts, communication standards and
vehicular applications. This paper also presents a survey on routing protocols for VANETs and simulation results for Distributed Robust Geocast.
