Performance analysis of AODV and DSDV routing protocol in MANET

This research focuses on a performance analysis of two prominent routing protocols in Mobile Ad-Hoc Networks (MANETs): Ad-Hoc On-Demand Distance Vector (AODV) and Destination-Sequenced Distance Vector (DSDV). The study utilizes the NS-2.35 simulation tool to evaluate these protocols under various network conditions using three key performance metrics: Packet Delivery Ratio (PDR), End-to-End Delay, and Routing Overhead. Simulations were conducted with node counts of 10, 20, 30, and 40 in a 500m x 500m area, operating under a random waypoint mobility model. The findings reveal that AODV outperforms DSDV in terms of PDR and Routing Overhead, showing significant improvements, such as an 88.58% decrease in routing overhead at 10 nodes. However, DSDV shows a better performance in terms of End-to-End Delay, especially in stable environments with fewer nodes. The results suggest that AODV is more suitable for dynamic and larger networks, while DSDV is better for smaller, less mobile networks. This comparative analysis highlights the importance of selecting an appropriate protocol depending on specific network conditions and application needs. The implications of these findings extend to optimizing routing protocols for various real-time applications in MANETs, offering a valuable contribution to enhancing the efficiency and reliability of wireless communication systems.
