Comparative Study of Enhanced AODV Routing Protocols in VANET

Abstract

Vehicular Ad-hoc network (VANET) is a self-organizing and infrastructure less network i.e. used to provide communication between Vehicle-to-Vehicle and Vehicle to Road Side Units (RSUs). It is one of the influencing research area that have been used in wireless communication for the better improvement of Intelligent Transportation Systems (ITS) because it has tremendous potential to provide a safe and comfortable environment for the driver and passenger along with allied services in the cases of emergencies. The primary purpose of VANET is to support vehicular safety, passenger security, traffic monitoring and other commercial application. Currently, a lot of research work has been carried out on several specific areas like Routing, Security and Quality of Service (QoS). However, VANET has very dynamic topology in nature, in large & variable network size and constrained mobility; these characteristics led to the need for efficient routing and resource saving protocol. The most widely used protocol in VANET is AODV. There are several enhancements which are proposed in AODV. In this paper, we have studied & analyzed several AODV enhancements as well as their comparative analysis in a realistic VANET context. General Terms Standardization, Design, Performance
