Abstract
The research on managing resources and bandwidth evaluation within ad-hoc networks has highlighted energy-efficient routing protocols as a critical mechanism for conserving energy and prolonging the network's operational lifespan. This study introduces the Energy-Efficient Power Aware DSR (EEPW-DSR) routing protocol, which enhances Cluster Head (CH) selection by incorporating a distance-aware approach and addresses energy consumption challenges. The proposed method optimizes CH selection based on proximity to the Base Station (BS) and the node energy levels, significantly reducing communication distance and balancing energy consumption. Conventional methods, such as Standard DSR and Multi-hop Routing (MR), were considered for comparative performance analysis with the EEPW-DSR. Simulation results demonstrate that the proposed method outperforms conventional methods in network lifetime, network stability, and period of active node operation. These improvements highlight the robustness of the proposed approach in ensuring network longevity in both homogeneous and heterogeneous Wireless Sensor Networks (WSNs).
