Performance Evaluation of AODV & DSR with Varying Pause Time & Speed Time Over TCP & CBR Connections in VANET

TL;DR

This paper evaluates the performance of AODV and DSR routing protocols in VANETs under different mobility parameters and traffic types, highlighting their efficiency and reliability in dynamic vehicular environments.

Contribution

It provides a comparative analysis of AODV and DSR protocols considering various mobility and traffic scenarios in VANETs, which was not extensively studied before.

Findings

AODV outperforms DSR in packet delivery ratio at higher speeds.

Both protocols show increased delay with higher node density.

Performance varies significantly with pause time and traffic type.

Abstract

VANET (Vehicular Ad-hoc Network) is a new technology which has taken enormous attention in the recent years. Vehicular ad hoc network is formed by cars which are called nodes; allow them to communicate with one another without using any fixed road side unit. It has some unique characteristics which make it different from other ad hoc network as well as difficult to define any exact mobility model and routing protocols because of their high mobility and changing mobility pattern. Hence performance of routing protocols can vary with the various parameters such as speed, pause time, node density and traffic scenarios. In this research paper, the performance of two on-demand routing protocols AODV & DSR has been analyzed by means of packet delivery ratio, loss packet ratio & average end-to-end delay with varying pause time, speed time and node density under TCP & CBR connection.
