Efficient communication in Mobile Ad-Hoc Networks (MANET) is essential due to their decentralized nature and reliance on battery-powered devices, making energy efficiency critical for network longevity. The primary challenge lies in optimizing energy consumption as constant node movement and interaction can rapidly deplete device batteries. This paper evaluates the residual energy in MANET by comparing two reactive routing protocols: Ad-hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR). The purpose is to determine which protocol maintains better residual energy under different mobility scenarios by using an energy model to calculate transmission, reception, idle, and sleep energy consumption. Using Network Simulator 2.35 (NS-2.35), network environments were created with 50, 100, 150, and 200 nodes, and both protocols were implemented to assess energy consumption at mobility speeds of 2 m/s and 4 m/s. The energy model calculated energy usage based on power consumption rates for various node activities. The analysis focused on residual energy, end-to-end delay, throughput, and packet delivery ratio (PDR). Results indicated that AODV generally outperforms DSR in terms of energy efficiency, lower end-to-end delay, and higher throughput, particularly in dynamic and high-density scenarios. These findings provide practical guidance for selecting optimal routing protocols to enhance energy consumption and performance in MANET, thereby improving network longevity and operational efficiency in various environments.
