Quality Of Service (QoS) Framework For Vehicular Communications In VANETS Focused On Message Characteristic Detections

Abstract

Vehicular Ad-Hoc Networks (VANETs) are well recognized as a potential technology to improve road safety and promote efficiency in the transportation system. Delivering Quality of Service (QoS) for VANET is a serious challenge, due to mobility features of vehicles. This paper also investigates state of a art QoS-based framework for VANETs that applies message properties to recognize and assign priority means to the messages. Through this proposed method, the adjustment of network configurations is performed, allowing the critical messages to be prioritized and transmitted as per the guarantee. The proposed model obtained a 95.14% packet delivery ratio, 4.86% end-to-end delay, 93.62% network throughput, 89.98% Transmission Data rate, and 93.87% Bandwidth Utilization. Simulation results prove the effectiveness of the proposed method in improving QoS parameters. With QoS support, VANETs can be used for practical applications, which can significantly improve VANETs by ensuring reliability and efficiency.
