An implementation of IPv6 AODV protocol in Vehicular Ad-hoc Network using NS-3 simulator

Abstract

Ad-hoc networks are designed to address specific communication needs in dynamic environments. Among them, Vehicular Ad-hoc Networks (VANETs) represent a special class of ad-hoc systems intended to enable reliable communication between vehicles and Road Side Units (RSUs) under conditions of high mobility and frequent topology changes. With the rapid growth of wireless-enabled devices, efficient routing has become a crucial challenge. One widely used routing protocol in VANETs is the Ad-hoc On-Demand Distance Vector (AODV). However, IPv4 addressing presents limitations in scalability and adaptability due to the large number of nodes and the highly dynamic nature of vehicular environments. To overcome these constraints, this work proposes an IPv6-based implementation of the AODV protocol for VANETs. Several simulation scenarios are conducted to evaluate and compare the performance of the IPv6 and IPv4 addressing schemes within the VANET context.
