Energy aware system operation, and not just low power hardware,is an important requirement for wireless embedded systems.These systems, such as wireless multimedia terminals orwireless sensor nodes, combine (soft) real-time constraints oncomputation and communication with requirements of long batterylifetime.In this paper, we present an OS-directed dynamicpower management technique for such systems that goes beyondconventional techniques to provide an adaptive power vs. fidelitytrade-off.The ability of wireless systems to adapt to changing fidelityin the form of data losses and errors is used to tradeoff againstenergy consumption.We also exploit system workload variationto proactively manage energy resources by predicting processingrequirements.The supply voltage, and clock frequency areset according to predicted computation requirements of a specifictask instance, and an adaptive feedback control mechanismis used to keep system fidelity (deadline misses) within specifications.
