“…Transmission power control and beacon rate control are two main examples of adaptation approaches. The authors in [4], [24], [25], [20], [26], [15], [27] have proposed adaptation approaches to tune transmission power with varying vehicular densities. That is, the purpose is to reduce transmission power in dense vehicular scenarios and hence improve fairness.…”

“…In other words, event driven messages have highest priority and maximum transmit power as compared to the periodic beacon message. For the fast dissemination of beacon safety messages, the authors in [4,29] proved desirable and satisfactory performance of beaconless geographical forwarding. According to this forwarding mechanism, the emergency message is transmitted to all neighbour nodes and they independently elect themselves as a next forwarder.…”

“…However, rapid changes in traffic density from sparse to heavy, as well as periodic beaconing between vehicles, can cause the wireless channel between vehicles to promptly become congested, resulting in a high degree of performance degradation of vehicular network [3], [4], [5]. The reason for this channel congestion is that each vehicle periodically broadcasts beacons at a fixed rate.…”

A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Beaconing approaches is an important research challenge in high mobility vehicular networks with enabling safety applications. In this article, we perform a survey and a comparative study of state-of-the-art adaptive beaconing approaches in VANET, that explores the main advantages and drawbacks behind their design. The survey part of the paper presents a review of existing adaptive beaconing approaches such as adaptive beacon transmission power, beacon rate adaptation, contention window size adjustment and Hybrid adaptation beaconing techniques. The comparative study of the paper compares the representatives of adaptive beaconing approaches in terms of their objective of study, summary of their study, the utilized simulator and the type of vehicular scenario. Finally, we discussed the open issues and research directions related to VANET adaptive beaconing approaches.

Vehicle-to-vehicle communications can be used effectively for intelligent transport systems (ITS) and location-aware services [1]. The ability to disseminate information in an ad-hoc fashion allows pertinent information to propagate faster through the network. In the realm of ITS, the ability to spread warning information faster and further is of great advantage to the receivers of this information. In this paper we propose and present a message-dissemination procedure that uses vehicular wireless protocols for influencing traffic flow, reducing congestion in road networks. The computational experiments presented in this paper show how an intelligent driver model (IDM) and car-following model can be adapted to 'react' to the reception of information. This model also presents the advantages of coupling together traffic modelling tools and network simulation tools.

“…We had integrated the results presented in [TMSH07] into ns-2. We had also tested several monotonically decreasing functions for the curve tting process and found that an optimum trade-o between accuracy and execution time could be achieved using a third order polynomial (see Equation 7.1):…”
