Towards Efficient Routing in VANETs: Insights from AODV, OLSR, and DSDV

Abstract

Vehicular Ad Hoc Networks (VANETs) require routing since they have unique problems due to their lack of fixed infrastructure and centralized administration. The performance of three crucial routing protocols-Ad-hoc On-demand Distance Vector (AODV), Optimized Link State Routing (OLSR), and Destination Sequenced Distance Vector (DSDV)—in the dynamic VANET environment is examined in this extensive survey study. The study starts by examining each routing protocol's theoretical foundation, outlining its advantages and operational guidelines. After that, an experiment involving a network simulation is conducted close to Bennett University. To represent various traffic situations, the experiment is divided into four scenarios, each with a different number of vehicles. We assess the effectiveness of AODV, OLSR, and DSDV by closely examining important metrics such packets delivered and received and Quality of Service (QoS) attributes. QoS metrics include things like throughput, packet delivery ratio, packet loss ratio, and end- to-end delay. With an emphasis on the automotive context, the results, which are displayed as thorough readings and graphs, paint a complex picture of how these protocols function under different network loads and sizes. This survey article offers useful implications for the design and optimization of communication systems in dynamic vehicular networks, which contributes to the comparative study of routing protocols in VANETs.
