Comparative Analysis of DSR, AODV, AOMDV and AOMDV-LR in VANET by Increasing the Number of Nodes and Speed

Abstract

Objectives: To analyze different VANET routing methods. Methods: The simulation result of reactive, proactive and hybrid multipath routing protocols is obtained in NS-2.34 by increasing the number of nodes and mobility. The outcomes are summarized in tables and figures. Findings: After simulation and comparison of existing protocols and the latest hybrid protocol, we found that the latest hybrid routing protocol gives the best result in the case of a higher number of participants and of high speed with minimum overhead. Novelty : In previous reviews and research, reactive and proactive routing protocols were compared. In this review, we compared the recently implemented hybrid protocol AOMDV-LR with the existing proactive and reactive protocol which gives better results.
