“…Indeed, by exploiting the interactions between various layers of the network stack, the cross-layer design can play a critical key role in overcoming current communication limitations. Our proposed paper builds on the obtained previous results [7][8] and addresses some of the most challenging open problems in the field.…”

Vehicular Ad-hoc Networks (VANETs) are advanced network technologies applied to improve safety on roads and to offer suitab le solutions for Intelligent Transportation Systems (ITS). The goal of VANETs is to assistdrivers and to act as a smart co-pilot that can alret ab out accidents and help avoiding them while prodivding high-end infotainment systems for b oth the driver and passengers. Consequently, VANETs can save millions of lives around the world, especially in Saudi Arab ia, which has a very high rate of road accidents annualy. In this paper, we introduce and discuss VANETs, related routing protocols, challenging prob lems, and the existing solutions. This work is a part of a b igger project that aims to enhance VANETs technologies and to updapteITS to sign ificantly promote road safety in general and Saudi Arab ia's roads in particular.

“…Over the last decades, probabilistic broadcasting schemes have been implemented using several techniques such as probabilistic density-based schemes [3]- [8], probabilistic counter-based schemes [9][10] and [11], probabilistic GPSbased schemes [12][13] [14], and probabilistic algebraic-based scheme [15]. Several studies show that probabilistic schemes that depends on a GPS device are the appropriate solutions for several communication scenarios in VANETs.…”

“…Based on the collected information from DL1, DL2 and DL3, the rebroadcast probability value that to be used in the high-density regime is calculated as follows: www.ijacsa.thesai.org (8) The WM must be queued with the high priority at MAC layer.

“…Usually, vehicles are considered inside the high-density regime if it travels with speed less than 10km/h. In this case, the rebroadcasting probability is set dynamically with respect to different density levels that are calculated in (8). For instance, when the vehicle A receives the WM from the emergency vehicle, it calculates DL1, DL2, DL3, P and Time_Delay as follows: www.ijacsa.thesai.org…”

In intelligent transportation systems, broadcasting Warning Messages (WMs) by Vehicular Ad hoc Networks (VANETs) communication is a significant task. Designing efficient dissemination schemes for fast and reliable delivery of WMs is still an open research question. In this paper, we propose a novel messaging scheme, Advanced Speed and Density Warning Message (ASDWM). ASDWM is a broadcast-based scheme that meets design objectives and achieves high saved rebroadcast and reachability, as well as low end-to-end latency of WM delivery. The ASDWM uses vehicle speeds and vehicles density degrees to help emergency vehicles to send WM according to a road condition, adaptively. Simulation results demonstrate the effectiveness and superiority of the ASDWM over its counterparts.

“…The speed adaptive probabilistic flooding algorithm [19] and the weighted p-persistent, slotted 1-persistent, and the slotted p-persistent are examples of probabilistic protocols [20]. In [21], an adaptive probabilistic protocol is proposed where, on one hand, vehicles in a dense network have a low probability of rebroadcasting messages and, on the other hand, in a sparse network they have a higher rebroadcast probability.…”

Vehicular ad hoc networks (VANETs) have been proposed in order to assist the driver on the road. There are multiple applications where VANETs are needed, for example, proposing routes to reach a given destination, cooperating for traffic management, or preventing the driver of dangers on the road. In this paper, we focus on message broadcast for driver safety. Such broadcasting must be fast and reliable such that all the vehicles in a certain area receive the message as fast as possible. There are several proposals in the literature of broadcast protocols for critical messages in VANETs. In order to get a wide view of the different techniques to broadcast a message, we evaluate a set of protocols representing one or more broadcast techniques. Moreover, we propose PDB, a preset delay broadcast protocol with a fixed delay for vehicles attempting to retransmit a warning message, which provides a fast and reliable dissemination. We show that by adequately setting the waiting time for the relay candidates, we can significantly reduce the delay to cover a given area, while at the same time preserving a good reliability. Moreover, we model different techniques to broadcast an emergency packet in a VANET such as count-based, geographical, distance-based, and opportunistic, and thus we implement a subset of state-of-the-art protocols that implement one or more of those techniques. Finally, our research shows that stopping beacon transmissions when a warning message is detected does not provide a significant performance improvement. Nonetheless, by allowing a continuous channel access, we prove that the performance of any protocol might be greatly increased.
