ABSTRACT

          In recent years, new applications, architectures, and technologies have been proposed for

vehicular ad hoc networks (VANETs). Regarding traffic safety applications for VANETs, warning

messages have to be quickly and smartly disseminated in order to reduce the required

dissemination time and to increase the number of vehicles receiving the traffic warning

information. In the past, several approaches have been proposed to improve the alert

dissemination process in multihop wireless networks, but none of them were tested in real urban

scenarios, adapting its behavior to the propagation features of the scenario. In this paper, we

present the Profile-driven Adaptive Warning Dissemination Scheme (PAWDS) designed to improve the warning message dissemination process.
