Abstract: A Vehicular Ad Hoc Networks (VANETs) brings the breakthrough in industries. In highways the road safety and travel comfort are accomplished through vehicle-to-vehicle and vehicle-to-roadside unit communications. A major issue in safety application is to diffuse emergency message to all the other vehicles immediately without redundancy. There are number of works have been proposed to disseminate the emergency message, but those works suffer from delay and bandwidth consumption due to redundancy. This paper considers vehicle-tovehicle communication for emergency message diffusion without the assistance of roadside units. In this paper, an Emergency Message Diffusion for Accident Information (EMDAI) approach is proposed for the efficient communication of emergency message. The EMDAI approach ensures the broadcasting of Short Range Message (SRM) and Long Range Message (LRM) to all the vehicles with minimum delay. A Non-Redundant Acyclic Group (NAG) technique is introduced to form a group to avoid the broadcast storm problem. In addition, the proposed EMDAI approach provides assistance to the ambulance to reach the Point of Incidence (PoI) in a short span of time. The performance analysis is done on reliability, channel occupancy, delay, message transmission per involved vehicle and traffic clearance delay. The results prove that the proposed EMDAI approach outperforms the existing protocol.
