Abstract

Ad hoc routing is utilized in MANET to provide effective wireless communication between mobile nodes. The main issue with MANET is the frequent changes in network architecture. Different routing protocols come in various forms. Here, the Dynamic Source Routing (DSR), Ad hoc On-Demand Distance Vector (AODV), and Optimized Link State Routing (OLSR) protocols have all had their performance assessed. The various protocols were simulated using the OPNET Modeler simulator. As performance measures, we assessed the effectiveness of the routing protocols using three performance metrics. We can observe from the simulation research that various procedures have various features. In certain contexts, different protocols behave differently. Considering throughput, OLSR performs better than DSR and AODV. DSR outperforms AODV and OLSR based on end-to-end latency. Regarding normalized routing load, OLSR outperforms AODV and DSR.
