摘　　要：Efficient routing protocols are crucial for enabling secure communication among the highly mobile and self-configurable nodes in Vehicular Ad-Hoc Networks(VANETs). In this work, we present a performance evaluation of different routing protocols in VANETs based on the currently available research. Our study focuses on analyzing the strength and weaknesses of the routing protocols, namely, Ad-Hoc On-demand Distance Vector(AODV), Dynamic Source Routing(DSR), and Destination-Sequenced Distance-Vector(DSDV), under varying network conditions. We examine the protocols’ performance based on key metrics such as throughput, delay, and energy consumption. We also highlight the advantages and limitations of each protocol in different scenarios, such as varying vehicular densities and mobility patterns. Our results show that AODV outperforms DSR and DSDV in terms of throughput and delay, while DSR consumes the least energy. We also observe that the performance of the routing protocols varies with the density of vehicles and the mobility patterns of the nodes. Our study highlights the importance of conducting real-world experiments to evaluate the performance of routing protocols in VANETs, as they provide more realistic and accurate results than simulation-based studies. Our findings can help in the selection and design of efficient and secure routing protocols for VANETs.
