Adaptive routing, Emergency networks, Energy-efficient routing, Hybrid security, MANETAbstract
Mobile ad hoc networks (MANETs) are widely used in disasters and emergencies where fixed communication infrastructure is unavailable; however, limited battery power, dynamic topology changes, and security threats reduce their efficiency and reliability. This study proposes an adaptive energy-efficient routing strategy for disaster-resilient emergency MANETs. A hybrid routing framework integrating energy-aware routing with dynamic security mechanisms is designed to address these challenges. The system continuously monitors node energy levels and adjusts routing paths accordingly, assigning heavier tasks to high-energy nodes while allowing low-energy nodes to conserve power. Simulations were conducted under varying node densities and mobility conditions to evaluate performance metrics, including energy consumption, network lifetime, packet delivery ratio, and routing overhead. The results show reduced energy consumption and extended network lifetime compared with existing approaches. The proposed method maintains a high packet delivery ratio with moderate routing overhead while ensuring adaptive security. Overall, the strategy effectively balances energy efficiency and secure communication in emergency MANET environments, providing a reliable and practical solution for disaster-resilient wireless networks. Future work may include evaluating performance in larger, heterogeneous networks and integrating advanced, lightweight security techniques and diverse mobility models to enhance performance further.
