“…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.…”

“…However, the performance network might be deteriorated in terms of excessive packet delay and unreliability of beacon message dissemination in case of using naive beacon broadcasting service. To alleviate the problem of simple broadcasting, three key parameters can be adapted to vehicular network scenarios; beacon generation rate, beacon transmission power and contention window of the Medium Access Control (MAC) layer [44], [45], [15].…”

“…Following the trend, the authors in [15] proposed a joint dynamic adjustment of transmission power and contention window size. The adaptation of transmission power by first computing communication range and then using that range to determine the power level.…”

“…Thus, dynamic transmission power adaptation is an imperative need in such bipolar traffic distribution environment [13], [14]. On the other hand, quality of service differentiation of various applications are very important in VANET since vehicles might expose to different incidents [15].…”

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.

Summary Internet of Vehicles is recorded as an ever growing area for connected vehicles to exchange their information with other vehicles using vehicle‐to‐vehicle communication. Vehicle‐to‐vehicle communication is possible by forming vehicular ad hoc networks, with the help of roadside units using vehicle‐to‐roadside communications in the network. Internet of networks has many advantages such as road safety, traffic management, and sharing information on daily traffic and updating traffic information. For example, the Internet of Vehicles can be used to reduce traffic and deaths occurring due to road accidents, to reduce the fuel needed, and to reduce travel time. Interconnected vehicles rapidly learn about road conditions and traffic and respond to the driver; thus, necessary actions are taken. However, the attacker can modify the information in the connected vehicles and, thus, creates problem on the road. Data fascination is one of the main attacks on connected vehicles where connected vehicles take action based on information from the other vehicle. In this paper, first, a model has been proposed to detect the data fascination attack using the hashing technique to enhance the security in the interconnected vehicles by adjusting the size of the contention window to transfer original information to other interconnected vehicles at the correct time. Second, a model has been suggested to reduce the travel time in case of traffic congestion. The efficiency of the proposed model is checked using numerical methods obtained from the simulation results. From the obtained results, the proposed approach prevents data fascination attacks in interconnected vehicles and provides high throughput with lower delay.
