Real Time Traffic Density Aware Road based Forwarding Method for Vehicular Ad hoc Networks

Abstract

Real time data dissemination is one of the significant requirement and also a challenge during data forwarding in Vehicular Ad hoc Networks (VANETs). High vehicular mobility causes various constraints in the shape of high scale of disconnections, packet dropping, delay in inter vehicle communication. Extensive investigation has been conducted to design reliable and efficient routing protocol for real time data dissemination in the network. However, still the existing routing protocols have suffered to handle high mobility, dynamic traffic patterns, traffic density estimation and other physical parameters in the network. This paper presents a Real time Forwarding Method (R-FM) for next hop selection by distance, direction, link quality and real time traffic density information. The proposed data forwarding method minimizes the generated communication overhead during data dissemination and ensures in time data delivery in the network. The experimental results show that proposed method improves the data forwarding as well as keeps high data delivery.
