Performance Improvement in VANET by Modifying AODV Routing Protocol

Abstract

A Vehicular Ad hoc network (VANET) is a type of peer-to-peer wireless network that allows providing communication between vehicles and nearby fixed roadside equipment. Vehicular ad hoc networks (VANETs) are classified as an application of Mobile Ad hoc Network (MANET)  that has the potential in improving road safety and in providing travellers comfort. In VANET due to fast vehicle movements the link topology changes rapidly hence lifetime of connection is short, hence dissemination of data is challenging in VANET and basic routing protocols cannot work efficiently. In this paper we improve the performance of Vehicular Ad-hoc Network (VANET) by modifying Ad-hoc On-demand Distance Vector (AODV) routing protocol, we compare proposed Improved Ad-hoc On-demand Distance Vector (IAODV) routing protocol with basic AODV protocol  in terms of network parameter Average End-to-End Delay.
