Abstract

Internet of Vehicle (IoV) dominates the traditional concept of Vehicular Ad-hoc Network (VANET) to boost the capabilities of Intelligent Transportation System (ITS). Frequent deployment of high-speed vehicles with more enhanced features by vehicle manufacturers expands the variety of challenges for ITS. This technological enhancement enables vehicles to exchange information across other vehicles and existing communication infrastructures. When a vehicle detects any critical trouble, it transmits an emergency message (EM) to nearby vehicles and to the traffic control office as an alert message to take necessary actions. The main issue is congestion if each vehicle is authorized to broadcast warning messages constantly. This congestion may lead to delays in the transmission of critical emergency messages with the redundant receiving of the same EM at the traffic control office. In our proposed scheme, called Beacon-oriented Emergency Message Dissemination (BEMD), we proposed a novel technique to enhance coverage and distribution of EM with the least delay. We aim to implement beacon-oriented communication for traffics with high mobility and sparse density on highways. We furthermore fixated on the least dependence of density on EM dissemination. As compared to the latest existing schemes, BEMD shows enhanced simulated results of more than 13%, 26% and 4% in terms of information coverage, delay and packet distribution ratio (PDR) respectively.
