Simulation and Performance Analysis of Manet in Post-Disaster Areas Utilizing Proactive Routing Protocol (Case Study: Palu Earthquake 2018)

Indonesia, situated at the convergence of active tectonic plates and surrounded by active mountain ranges known as the Ring of Fire, enjoys advantages such as fertile land and a tropical climate. However, these benefits also pose threats when nature is not in its best state, rendering certain regions of Indonesia susceptible to natural disasters. The consequences not only entail material and human losses but also extend to the detriment of critical infrastructure, including communication networks. Communication disruptions in crucial conditions undoubtedly hinder rescue and recovery efforts. This study focuses on designing communication scenarios based on Mobile Ad-hoc Network (MANET) as a post-disaster communication solution, utilizing the NS-3 simulator with proactive routing protocols OLSR and DSDV, alongside an analysis of their performance in scenarios involving the addition of nodes. Performance metrics, including Packet Loss, Throughput, and Delay, are compared based on the TIPHON QoS standard. The experimental results demonstrate the superiority of OLSR routing performance over DSDV, with the best average throughput value at 2292.57 Kbps, a delay of 76.98 ms, and a packet loss of 0.12% for a scenario involving 150 nodes. This research aims to provide an alternative solution for developing post-disaster emergency communication networks and contribute to post-disaster rescue and recovery efforts.
