        abstract = {This paper explores the impact of node deployment models on the performance of the Open Shortest Path First (OSPF) routing protocol in Mobile Ad Hoc Networks (MANETs) with a focus on scalability, utilizing the OPNET simulator. MANETs, characterized by their dynamic topologies and infrastructure-free design, require efficient and adaptive routing to maintain network performance as they scale. The OSPF protocol, traditionally employed in fixed networks, has been adapted with extensions such as the MANET Designated Router to enhance its functionality in mobile environments. Different node deployment models, including random, grid, and circular configurations, significantly influence routing efficiency, control overhead, and overall scalability of OSPF in MANETs.
This study simulates the performance of OSPF across various deployment models using the OPNET simulator, analyzing the effects of node density, mobility patterns, and network size on key performance metrics, including end-to-end delay and throughput. The results demonstrate that structured deployments—particularly random, grid, and circular models—provide enhanced scalability and stability for OSPF in MANETs by reducing the frequency of route updates and minimizing control message flooding. Furthermore, random deployments introduce diverse connectivity patterns and dynamic routing opportunities, which enhance adaptability as the network size increases. These findings underscore the significance of selecting optimal node deployment models to improve the scalability of OSPF in MANETs, offering practical implications for applications in military operations, emergency response, and mobile sensor networks.},
