Abstract

In intelligent transportation systems, the collaboration between vehicles and the road side units is essential to bring these systems to realization. The emerging Vehicular Ad Hoc Network (VANET) is becoming more and more important as it provides intelligent transportation application, comfort, safety, entertainment for people in vehicles. In order to provide stable routes and to get good performance in VANET, there is a need of proper routing protocols must be designed. In this paper, we are working with the very well-known ad-hoc on-demand distance vector (AODV) routing protocol. The existing Routing protocol AODV-L which is based on the Link expiration time is extended to propose a more reliable AODV-AD which is based on multichannel MAC protocol. For the performance evaluation of routing protocols, a simulation tool ‘NS2’ has been used. Simulation results show that the proposed AODV-AD protocol can achieves better performances in forms of high Route stability, Packet Delivery ratio and packet loss rate than traditional AODV-L and traditional AODV.

Highlights

  • There are various types of ad hoc networks and one of them is Vehicular Ad Hoc Network (VANET)

  • Making of enhanced algorithm which is the extended part of the ad-hoc on-demand distance vector (AODV)-L algorithm with the concept of multichannel medium access control (MAC) protocol

  • Simulation Setup and Results: first we are considering the performance metrics considering which the enhancement is done. After it the description of the simulation environment and the first part of the expected outcome is presented. It has the results of the comparison between the traditional AODV routing protocol and the AODV-L routing protocol by using simulator NS2.34

Summary

Introduction

There are various types of ad hoc networks and one of them is VANET. Vehicular Ad Hoc Network (VANET) is a subclass of Mobile Ad hoc Network (MANET). The communication between vehicles has some specifics such as high speed and mobility, and that is the key feature of vehicular ad-hoc networks that makes them unique in the context of MANETs. By using vehicle to vehicle communications, drivers can be notified of important traffic data such as the condition of roads and accidents. By using vehicle to vehicle communications, drivers can be notified of important traffic data such as the condition of roads and accidents Such information will improve drivers’ decisions in hard conditions. Routing algorithms are an important part of a vehicular ad hoc network where it forward information in order to connect vehicles and having communication between them. The proposed routing protocols and mechanisms that may be employed in VANETs should adapt to the rapidly changing topology
