Rapidly evolving wireless network technology continues to be one of the focal points in academic research. Mobile Ad hoc Networks (MANETs) consist of mobile nodes and the efficient transmission of data among these nodes is crucial for the network's operation. In this study, four of the most common routing protocols, namely AODV(Ad Hoc On-Demand Distance Vector), DSR(Dynamic Source Routing), OLSR(Optimized Link State Routing), and DSDV(Destination-Sequenced Distance Vector) were evaluated using different scenarios in the NS-2 simulation environment. As known, the lifetime of a wireless network is proportional to the battery limits of its nodes. Therefore, the choice of routing protocol for mobile ad hoc networks is critical for the network's lifetime. In this study, the energy consumption of the aforementioned routing protocols was analyzed under different conditions, and it was concluded that table-driven routing protocols, especially DSDV, demonstrated the best energy performance in various scenarios.
