Power-aware routing protocols

Definition

Power-aware routing protocols are networking strategies designed to optimize energy consumption within wireless and wired networks by adapting routing decisions based on the power state of nodes. These protocols aim to extend the lifespan of network devices, reduce energy costs, and improve overall network efficiency by minimizing power usage while ensuring reliable data transmission. By incorporating energy awareness into the routing process, they can balance performance and energy efficiency, making them essential in today's power-sensitive computing environments.
