QoS Routing Protocol (QoRP) to Enhance Road Safety in VANETs

Abstract

Vehicular Ad Hoc Network (VANET) communication promises a vast array of applications ranging from road safety and driving comfort. Safety message broadcasting plays a significant role in highway safety in which the safety alert messages have to be delivered immediately to the vehicles located in the risk boundary area. Most of the current research attempt to select optimal relayer for safety message rebroadcasting. However, relayer selection models are not efficient, especially in a high-density VANET, as they cause a high delay in safety message delivery and lead to multiple accidents at the incident spot. To avert these issues, this work proposes a QoS Routing Protocol (QoRP) that aims to enhance the road safety in both sparse and dense VANETs.
