We present our experience with Twinkle, the first implementation of network-layer power scheduling with real applications. Twinkle uses dynamically created schedules to schedule network flows in sensor networks. The scheduling allows nodes to turn off their radio when idle, thus saving power. Twinkle supports broadcast and partial flows for flexibility, and integrates time synchronization to enable scheduling to work on real motes. We show that it avoids contention, increases fairness, and that it can achieve power savings of 2-5x for real applications over existing power-management schemes, and over 150x compared with no power management. Finally, we discuss the extensions to the original algorithm needed for real applications.
