An Intervehicular Communication Architecture for Safety and Entertainment

Abstract

Abstract-Inter-vehicle communication (IVC) is emerging in research prominence for the interest that isgenerating in all major car manufacturers and for the benefits that its inception will produce. The specific features of IVC will allow the deployment of a wide set of possible applications which span from road safety to entertainment. Even if, on the one hand, these applications share the common need for fast multi-hop message propagation, on the other hand, they possess distinct characteristics in terms of generated network traffic. The current research state of the art only proposes solutions specifically designed for a single application (or class) that are not directly extendable to a general IVC context. Instead, we claim that a privileged architecture exists, which is able to support the whole spectrum of application classes. To this aim, we propose a novel IVC architecture that adapts its functionalities to efficiently serve applications in quickly propagating their messages over a vehicular network. We conducted an extensive set of experiments that demonstrate the efficacy of our approach. As representative case studies, we considered two application classes that for their network traffic characteristics are at the opposite boundaries of the application spectrum: safety and entertainment.

On the Effectiveness of an Opportunistic Traffic Management System for Vehicular Networks

“…Previous studies [24], [25], [26], [27], [28] show how the performance of traditional Ad-Hoc routing dissemination is heavily affected by vehicle density in urban areas. Conversely, gossip-based Ad-Hoc routing is very effective [29] in disseminating large amounts of information in dense networks and this is why we choose a utility-based gossip model in CATE.…”

An optimal 1D vehicular accidentwarning algorithm for realistic scenarios

“…Authors of [8] fix this problem by devising an algorithm that assesses the actual transmission range for every car in the platoon. A result of this algorithm are in general lower delays in forwarding alarm messages.…”

Modeling and Experimenting with Vehicular Congestion for Distributed Advanced Traveler Information Systems

“…Table 5 shows the functionalities a broadcasting scheme should implement to rapidly spread traffic information as far as possible. This is a complex issue which can be summarized as follows [12]- [20]. Every time a given vehicle receives SendMessage(message, nextRelay); 5: end a message, this is delivered to the ATIS application which will permit to that vehicle to construct a picture of the traffic situation concerning the roads surrounding it (line 1).…”
