Abstract Managing power consumptionwhile simultaneouslydelivering acceptablelevels
of performance is becoming a critical issue in several application domains such
as wireless computing. We integrate compiler-assisted techniques with power-
aware operating system services and present scheduling techniques to reduce
energy consumption of applications that have deadlines. We show by simula-
tion that our dynamic power managementschemes dramatically decrease energy
consumption.

1. Introduction
As the remarkable advances in VLSI and communication technologies have
culminated in a proliferation of mobile, embedded and wireless computers in
the last decade, system designers are faced with a relatively new and difficult
