“…It is evident that small beacon rate will alleviate link congestion at the cost of information accuracy. There are many schemes in literature that use different parameters to adapt beacon rate [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. The following is the short summary of adaptive beacon rate control algorithms.…”

Beacon or safety messages are broadcasted in vehicular ad hoc networks (VANETs) to disseminate network state or emergency incident information to other vehicles in the network. The freshness of information depends upon the frequent transmission of beacons. Similarly, to increase the awareness area or communicating with the distant nodes, beacons are disseminated with a high transmission power. However, increasing the beacon transmission power or rate has a negative effect on information communication efficiency because of the finite bandwidth of the wireless link. Therefore, different schemes have been proposed to individually control beacon's transmission power, transmission rate, or contention window at the MAC layer, or any combination of those, to achieve quality beacon communication in VANETs. The latter case is called hybrid adaptive beaconing schemes. In literature, there are many hybrid adaptive beaconing schemes that control multiple communication parameters to efficiently broadcast beacon messages in VANETs. In this paper, we explicitly survey and summarized various aspects of those schemes. The open and challenging issues are also highlighted in this paper.

“…However, most of congestion control algorithms are directly applicable for event-driven safety messages. In research paper [8] a congestion control approach based on the concept of dynamic priorities-based scheduling has been discussed. They have evaluated dynamic priority factor based on: node speed consideration, message utility consideration and message validity consideration.…”

Mobile ad hoc network (MANET) is a collection of mobile computers or devices that cooperatively communicate with each other without any pre-established infrastructures such as a centralized access point. There are several issues in VANET. One of them is congestion control. In case of increase in the number of beacon messages broadcasted by many vehicles, the communication channel will easily be congested. So, to overcome this problem we have proposed an algorithm that increases the availability of communication channel for emergency messages over the beacon messages.

“…Measuring the channel usage level is too difficult to analyse under realistic environment due of the different traffic load. In a similar study in [9], they proposed congestion control algorithm for DSRC based on safety applications. However, they just assumed the CCH channel is successfully reserved for event-driven applications without testing the successfully rate for event-driven safety messages.…”

“…However, they just assumed the CCH channel is successfully reserved for event-driven applications without testing the successfully rate for event-driven safety messages. In research [9], they set the channel occupancy time as threshold. If channel occupancy time measured at a node in CCH interval is longer than a given threshold, all beacon safety messages will be blocked immediately in the remainder of that CCH interval and the CCH interval followed to reduce channel load and reserve space for event-driven safety messages.…”

-A Vehicular Ad-Hoc Networks (VANETs) is the technology that uses moving cars as nodes in a network to create a mobile network. VANETs turn every participating car into a wireless router, allowing cars of each other to connect and create a network with a wide range. VANETs are developed for enhancing the driving safety and comfort of automotive users. The VANETs can provide wide variety of service such as Intelligent Transportation System (ITS) e.g. safety applications. Many of safety applications built in VANETs are required real-time communication with high reliability. One of the main challenges is to avoid degradation of communication channels in dense traffic network. Many of studies suggested that appropriate congestion control algorithms are essential to provide efficient operation of the network. However, most of congestion control algorithms are not really applicable to event-driven safety messages. In this paper we propose congestion control algorithm as solution to prevent congestion in VANETs environment. We propose a complete validation method and analyse the performance of our congestion control algorithms for event-driven safety messages in difference congested scenarios. The effectiveness of the proposed congestion control algorithm is evaluated through the simulation using Veins simulator.
