Performance Evaluation of Aodv&DSR with Varying Pause Time & Node Density Over TCP&CBR Connections in Vanet

TL;DR

This paper evaluates the performance of AODV and DSR routing protocols in vehicular ad hoc networks, analyzing how parameters like pause time and node density affect key metrics under TCP and CBR traffic.

Contribution

It provides a comparative analysis of AODV and DSR performance in VANETs considering multiple network parameters and traffic types, which is less explored in existing literature.

Findings

AODV and DSR show different performance trends with varying pause time and node density.

Packet delivery ratio varies significantly between protocols under different conditions.

End-to-end delay is affected by mobility parameters and traffic types.

Abstract

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 and node density under TCP & CBR connection.
