Real-time embedded systems (RTES) found in many real-world applications demand that timing requirements for computations and communications are satisfied. In addition, energy consumption is becoming a major consideration for such systems, because of the proliferation of mobile, wireless, and embedded systems with limited energy resources. Energy consumption significantly impacts the cost, performance, and life time of such systems. This research addresses the lack of system-wide energy conservation approaches by developing integrated scheduling techniques to reduce the overall energy consumption of wireless real-time systems while meeting applications' timeliness requirements. Integration in this context refers to reducing the energy consumption of a system as a whole by maximally exploiting the Dynamic Voltage Scaling (DVS) capabilities of CPU cores and the Dynamic Power Management (DPM) capabilities of other resources and devices. Important results of this work are novel and highly applicable algorithmic techniques for energy-efficient RTES. The broader impacts of this project can be found in both education and research, in addition to its enormous social impacts due to the pervasiveness of real-time systems and environmental concerns. The results of the experimental studies are being made available online for other researchers to pursue their own research and education interests.The effort also helps greatly to alleviate the problem of many theoretical system-level power reduction techniques not being adopted due to the lack of sound studies based on actual hardware platforms.

许多实际应用中的实时嵌入式系统 (RTES) 都要求满足计算和通信的时序要求。此外，由于能源资源有限的移动、无线和嵌入式系统的激增，能源消耗正成为此类系统的主要考虑因素。能源消耗显着影响此类系统的成本、性能和使用寿命。该研究通过开发集成调度技术来解决系统范围内节能方法的缺乏，以降低无线实时系统的整体能耗，同时满足应用程序的及时性要求。这里的集成是指通过最大限度地利用CPU内核的动态电压调节（DVS）功能以及其他资源和设备的动态电源管理（DPM）功能来降低整个系统的能耗。这项工作的重要成果是针对节能 RTES 的新颖且高度适用的算法技术。除了由于实时系统的普遍性和环境问题而产生的巨大社会影响之外，该项目还可以在教育和研究方面产生更广泛的影响。实验研究的结果正在网上发布，供其他研究人员追求自己的研究和教育兴趣。这一努力也极大地缓解了许多理论系统级功耗降低技术因缺乏健全而未被采用的问题。基于实际硬件平台的研究。
