Optimizing Routing Efficiency in MANETs: A Simulation-Based Comparison of AODV and DSR Protocols

Abstract

Mobile Ad Hoc Networks (MANETs) are characterized by their dynamic topology, decentralized control, and frequent node mobility, making efficient routing a critical challenge. This paper presents a comprehensive simulation-based analysis of two widely used reactive routing protocols in MANETs: Ad hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR). Using the NS-2 simulator, we evaluate and compare their performance under varying conditions including node density, mobility speed, and traffic load. The study aims to identify optimal configurations that enhance routing efficiency. Performance metrics such as Packet Delivery Ratio (PDR), End-to-End Delay, Throughput, and Routing Overhead are considered. The results provide insights into the adaptability and robustness of AODV and DSR, and guide the selection of routing strategies for efficient MANET deployment.
