Sonu Kumar, Ambuj Bhushan Gautam, Kapil Govil . Performance Evaluation of AODV and DSR Routing Protocols with Increasing Network Size in MANETs. International Journal of Computer Applications. 187, 90 ( Mar 2026), 45-51. DOI=10.5120/ijca2026926594
In mobile ad-hoc networks (MANETs), the implementation of efficient routing protocols is crucial for sustaining connectivity in environments devoid of infrastructure. This research examines the comparative effectiveness of two commonly utilized reactive routing protocols—AODV and DSR—via NS-2 simulations under increasing network size scenarios while maintaining comparable network connectivity. The focus of the analysis is on essential performance indicators such as packet delivery ratio, end-to-end delay, routing overhead, and throughput. The findings indicate that the performance of the protocols is predominantly influenced by network size and scalability effects, particularly regarding routing overhead, latency, and data delivery performance. The results highlight the importance of considering network size as a key factor when selecting routing protocols under controlled simulation conditions in MANETs. Unlike many existing studies that assume a fixed network size, this work emphasizes scalability behaviour by progressively increasing the number of nodes under uniform simulation conditions.
