This project focuses on new approaches to maximizing power consumption in handheld and other wireless devices by combining a network-centric view of the power-consumption issue (aximizing longevity for the network rather than device by devic) with the more traditional device-centric view (power management capabilities for the individual device). The project will model and evaluate new architectures and algorithms that allow the operating system to accept input from the applications and interact closely with the network for minimizing overall energy in the wireless system. The focus of the research is: 1) power-management of individual nodes 2) power-aware routing, in the sense that the power is minimized for the overall network and not only for individual messages or streams. 3) a combination of the variable voltage scheduling with the power-aware routing. It is anticipated that through algorithm development and analysis, simulation and testbed implementations, the results of this project will lead to a better understanding of how to provide more efficient power management to nodes with rechargeable batteries, and how to integrate CPU and network power management under one paradigm.

该项目将以网络为中心的功耗观点(最大化网络寿命，而不是逐个设备地使用设备)与更传统的以设备为中心的观点(单个设备的电源管理功能)相结合，重点介绍了使手持设备和其他无线设备的功耗最大化的新方法。该项目将对新的架构和算法进行建模和评估，这些架构和算法允许操作系统接受来自应用程序的输入，并与网络密切交互，以最大限度地减少无线系统中的总能量。研究的重点是：1)单个节点的功率管理2)功率感知路由，即对整个网络的功率最小化，而不仅仅是对单个消息或流的功率。3)可变电压调度与功率感知布线相结合。预计通过算法开发和分析、模拟和试验台实施，该项目的结果将有助于更好地理解如何为具有可充电电池的节点提供更有效的电源管理，以及如何在一个范例下集成CPU和网络电源管理。
