Abstract

With the advancement in communication technologies, Internet of vehicles presents a new set of opportunities to efficiently manage transportation problems using vehicle-to-vehicle communication. However, high mobility in vehicular networks causes frequent changes in network topology, which leads to network instability. This frequently results in emergency messages failing to reach the target vehicles. To overcome this problem, we propose a data dissemination scheme for such messages in vehicular networks, based on clustering and position-based broadcast techniques. The vehicles are dynamically clustered to handle the broadcast storm problem, and a position-based technique is proposed to reduce communication delays, resulting in timely dissemination of emergency messages. The simulation results show that the transmission delay, information coverage, and packet delivery ratios improved up to 14%, 9.7%, and 5.5%, respectively. These results indicate that the proposed scheme is promising as it outperforms existing techniques.

Highlights

The emerging domain of Internet of things (IoT) has transformed many fields, among them, the traditional vehicular ad hoc networks (VANETs) have transformed into a new paradigm of connected vehicles known as Internet of vehicles (IoV)
We propose a novel emergency message (EM) dissemination scheme
We used a clustering scheme based on interest compatibility (IC) metrics to form clusters and elect the cluster head (CH)

Summary

Introduction

The emerging domain of Internet of things (IoT) has transformed many fields, among them, the traditional vehicular ad hoc networks (VANETs) have transformed into a new paradigm of connected vehicles known as Internet of vehicles (IoV). IoV plays an important role in building a dynamic network of vehicles for improving the intelligent transport system (ITS), focusing on efficient information exchange among vehicles. It provides support for new applications such as road safety, entertainment, and traffic management, which were previously difficult to realize. With IoV, this revolution in VANETs can be seen as vehicles can share data and information with other vehicles and road side units (RSUs).
