A priority based broadcasting using Fast and Reliable Warning Messages dissemination mechanism for Inter Vehicular

Abstract

Vehicular Ad Hoc Networks (VANETS) differ from Mobile ad hoc networks (MANETs) in that they have high mobility and rapidly changing network topology. In addition, the topic of broadcasting emergency messages within a VANET has received considerable attention recently. Vehicles can periodically exchange their status with their neighbours, transmitting information collected via the Global Positioning System (GPS) in their OnBoard Unit (OBU). In this paper, a priority based broadcasting of messages is used with Fast and Reliable Warning Messages (FRWM) mechanism for inter vehicular communications. The experiment would be conducted with VANET highway scenario would be analyzed. The whole method is concerned with safety broadcasting among inter vehicular communications. The highway VANET scenario is considered for up to 100 vehicles with 3 lanes. The priority is given according to ambulance, police and ordinary vehicles. The simulative experiment is conducted using network simulator 2. The proposed method is compared with Appropriate Vehicular Emergency Dissemination (AVED) method in terms of parameters like reception rate, delay time and number of forwarding counts. The simulation results showed the improved performance of proposed FRWM method over AVED method.
