“…In order to meet these constraints, several contributions have been proposed in the literature in an attempt to address the data dissemination issues in vehicular environment by applying different dissemination strategies [8,13,29]. The most common solution whereby these strategies perform, is to select a set of relay nodes responsible for re-transmitting message, in order to reduce excessive transmissions.…”

The dissemination of road safety messages is a challenging task in VANETs. Indeed, they should be efficiently transmitted by achieving a high packet delivery within a limited transmission delay and a minimum of overhead. In order to meet these constraints, while overcoming the data dissemination challenges, researchers have proposed a wide variety of solutions. Most of these solutions are addressing the well-known Broadcast Storm problem. In this context, we propose in the current work a new dissemination strategy denoted ''READ'' for robust and efficient adaptive data dissemination protocol. On the one hand, the originality of this protocol lies in its robustness that is achieved through a smart relay selection. Therefore, a high data reliability is guaranteed based on a beaconless strategy while taking into account the surrounding vehicles' density. On the other hand, the protocol efficiency is manifested through the effective use of the limited network resources by reducing the excessive number of redundant messages. The simulation results show that the proposed solution achieves a high data reachability within a low transmission delay while using the minimum network resources. Furthermore, READ presents an adaptive feature that makes it suitable either for safety applications or for comfort application.

“…The main reason for which VANETs have been standardized consists in the deployment of real-time and safety applications for drivers and passengers: they are able to broadcast real-time alerts to drivers about risks on their planned journey and their immediate surroundings [3]. Under these considerations, it can be stated that especially in the last years, vehicular networks are promising in a number of useful driver and passenger oriented services which include, for example, on-demand Internet connections and multimedia services.…”

In the last years, vehicular networking has grown up in terms of interest and transmission capability, due to the possibility of exploiting the distributed communication paradigm in a mobile scenario, where moving nodes are represented by vehicles. The different existing standards for vehicular ad-hoc networks, such as dedicate short range communication (DSRC), wireless access for vehicular environment (WAVE)/IEEE802.11p, have given to the research community the possibility of developing new medium access control (MAC) and routing schemes, in order to enhance the quality and the comfort of mobile users who are driving their vehicles. In this paper, we focus our attention on the optimization of traffic flowing in a vehicular environment with vehicle-2-roadside capability. As shown later, the proposed idea exploits the information that is gathered by road-side units to redirect traffic flows (in terms of vehicles) to less congested roads, with an overall system optimization, also in terms of carbon dioxide emissions reduction. An analytical model, as well as a set of pseudo-code instructions, have been introduced in the paper. A deep campaign of simulations has been carried out to give more effectiveness to our proposal.

INTRODUCTIONI N THE last years, the interest in vehicular opportunities and potentialities has drastically grown, due to the numerous advantages inherited from mobility solutions in urban/suburban environments. In particular, Vehicular Ad-hoc NETworks (VANETs) represent a new and modern paradigm of communication, where the nodes are able to communicate in a distributed manner, based on the ad-hoc paradigm [1], [2].VANETs are going to be considered as one of the first adhoc networking reality in nowadays applications, enabling the transmission among nearby vehicles as well as between vehicles and nearby external devices. In fact, each node is equipped with a wireless device, the On-Board Unit (OBU), which is able to interact with the infrastructure equipment for comfort/security applications, trade and infotainment services.
