Simulation-Based Analysis of Routing Protocols in MANETs: INTSM, AODV, and DSDV Performance Review

Mobile Ad-Hoc Networks (MANETs) exemplify a dynamic and decentralized communication framework, enabling devices to form network connections spontaneously, thereby rendering them especially appropriate for situations with infrastructural limitations. The efficacy of MANETs is heavily influenced by the selected routing protocol and the density of network nodes. This chapter provides a thorough analysis of three significant routing protocols: the Intermediate Node Traffic Sharing Model (INTSM), Ad-Hoc On-Demand Distance Vector (AODV), and Destination-Sequenced Distance Vector (DSDV) across different node density scenarios.

This study encompasses comprehensive simulations and performance assessments inside the NS2 simulation framework to evaluate the efficacy of different routing protocols under varying node density conditions. The essential performance parameters, such as packet delivery ratio, end-to-end delay, network throughput, and routing overhead, across various node densities were examined. Through a comprehensive comparison, it was intended to offer significant insights into the behavior of these protocols and their adaptation to dynamic network settings.

The study in this chapter elucidates the performance of INTSM, AODV, and DSDV routing protocols amid variations in node density inside the NS2 simulation environment, providing essential insights for the optimal selection of protocols for certain MANET implementations. Moreover, this research study highlights the significance of accounting for network dynamics and diverse node populations in the design and optimization of mobile ad-hoc communication systems, particularly when employing simulation tools such as NS2 for assessment and analysis.
