In Vehicular Adhoc Network (VANET), the typical topology variations produced by the highly mobile nature of vehicle poses major issues in data transmission. The mobility and location based data dissemination techniques could satisfy the requirements of emergency message (EM) dissemination. It faces several issues in highway as well as urban roadways like minimum latency, highly secure, and scalable, which needs to be resolved. Generally, broadcasting protocols for VANET make use of beacon signals, which are distributed amongst the vehicles to attain information about the neighboring vehicles. With this motivation, this paper presents an energy aware cluster based routing protocol for the critical message dissemination (EAC-RPCMD) technique for VANET. The goal of the EAC-RPCMD technique aims to disseminate the EMs in the cluster based VANET environment. The EAC-RPCMD technique primarily designs an equilibrium optimizer based clustering (EOC) technique for the organization of vehicles into clusters. Besides, the manta ray foraging optimization (MRFO) algorithm based route selection (RS) technique, named MRFO-RS technique for optimal choice of routes to destination. Moreover, the EM dissemination scheme is also employed in the VANET. The performance validation of the EAC-RPCMD technique takes place and the results are inspected under several aspects.

“…VANET allows vehicles for communicating with each other either in parking areas/on roads. It enables vehicles to form a network of their own without centralized servers [1]. Each communication that takes place amongst vehicles is called vehicle to vehicle (V2V) transmission when the exchange of data among roadside units (RSUs) and vehicles are called vehicle to infrastructure (V2I) transmission.…”

Safety applications in Vehicular Adhoc Networks (VANET) are based on the dissemination of critical messages (CLMs) to numerous vehicles with minimal latency and packet loss. But the avoidance of broadcast storms and dealing with large scale dissemination of EMs in urban VANETs, predominantly at intersections, are challenging issues. These issues can be resolved by the clustering approach which can create a hierarchical structure by the organization of the nodes. In this view, this paper designs a metaheuristic optimization algorithm for cluster based reliable critical message dissemination (MOC-RCMD) in VANET. The proposed MOC-RCMD technique aims to organize the clusters and select CHs proficiently. In addition, the MOC-RCMD technique encompasses a two-stage process namely Shark Optimization Algorithm based clustering (SOA-C) and Seagull Optimization based Routing for Data Dissemination (SGO-RDD). The SOA-C and SGO-RDD techniques derive a fitness function involving different input parameters related to VANET. The design of MOC-RCMD technique for cluster-based CM dissemination shows the novelty of the study. A wide range of simulations take place and the results demonstrated the betterment of the MOC-RCMD technique over the recent approaches.

“…Though VANETs are coupled with many challenges data dissemination is an important one [3]. In general, normal messages are not time critical, in contrast, safety/emergency messages are time critical and require successful transmission at the earliest [25], [37].…”

Time Barrier-Based Emergency Message Dissemination in Vehicular Ad-hoc Networks

With the advancement in technology and inception of smart vehicles and smart cities, every vehicle can communicate with the other vehicles either directly or through ad-hoc networks. Therefore, such platforms can be utilized to disseminate time-critical information. However, in an ad-hoc situation, information coverage can be restricted in situations, where no relay vehicle is available. Moreover, the critical information must be delivered within a specific period of time; therefore, timely message dissemination is extremely important. The existing data dissemination techniques in VANETs generate a large number of messages through techniques such as broadcast or partial broadcast. Thus, the techniques based on broadcast schemes can cause congestion as all the recipients re-broadcast the message and vehicles receive multiple copies of same messages. Further, re-broadcast can degrade the coverage delivery ratio due to channel congestion. Moreover, the traditional cluster-based approach cannot work efficiently. As clustering schemes add additional delays due to communication with cluster head only. In this paper, we propose a data dissemination technique using a time barrier mechanism to reduce the overhead of messages that can clutter the network. The proposed solution is based on the concept of a super-node to timely disseminate the messages. Moreover, to avoid unnecessary broadcast which can also cause the broadcast storm problem, the time barrier technique is adapted to handle this problem. Thus, only the farthest vehicle rebroadcasts the message which can cover more distance. Therefore, the message can reach the farthest node in less time and thus, improves the coverage and reduces the delay. The proposed scheme is compared with traditional probabilistic approaches. The evaluation section shows the reduction in message overhead, transmission delay, improved coverage, and packet delivery ratio.
