Enhancing the throughput of a Node by Handling Congestion in Vanets using Efficient Queue Management

Abstract Vehicular ad-hoc network (VANET) is one of the most challenging domain in current scenario to provide an Intelligent transport system (ITS). One of the important application area of mobile ad-hoc network (MANET) is VANET. Few major challenges in VANET environment like network congestion, routing and securitywhich must be resolved to provide an efficient service to the user. This paper explores the effect of network layer congestion in the overall performance of VANET and proposes a framework to handle congestion in the VANET by providing efficient queue management. The proposed approach named Node Based Throughput (NBTH) is intended to evaluate the throughput of a node. Method proposed in this paper is being analysed with various parameters like throughput end_to_end delay and packet loss with respect to density of nodes.
