Recently, it has been recognized that power management to control temperature is vitally important. In fact, in May Intel abruptly announced that it had scrapped the development of two new computer chips (code named Tejas and Jayhawk) for desktops/servers in order to rush to the marketplace a more efficient chip technology more than a year ahead of schedule. Analysts said the move showed how eager the world's largest chip maker was to cut back on the heat its chips generate. Intel's method of cranking up chip speed was beginning to require expensive and noisy cooling systems for computers. There is an extensive literature on power management in computing devices, and there is an extensive literature on power management in ad-hoc and sensor networks. Yet almost all of this literature focuses on power management to conserve energy, and not on power management to reduce temperature. Temperature and energy are different physical entities with quite different properties. Bluntly, if the processor in your mobile device exceeds its energy bound, your battery is exhausted, but if your mobile device exceeds it thermal threshold, your processor dies.The need to manage power to reduce temperature will become increasingly important as device power consumption is growing exponentially, and as ad-hoc and sensor networks become more prevalent. We propose to reexamine power management problems from a temperature perspective to try to better understand the difference between managing power to conserve energy and managing power to minimize temperature. We plan to start with speed scaling problems within devices and with routing problems in ad-hoc networks. It is anticipated that this project will produce novel optimization techniques and analytical results that will be useful in the design of temperature-efficient protocols for large-scale ad-hoc and sensor networks. The work will be a joint inter-disciplinary effort, involving investigators with expertise in on-line algorithm design and in network protocol design and development. It is further anticipated that the project will provide students with a unique opportunity to investigate and experiment with new ways of thinking about important design parameters for this emerging class of networks.

近来，已经认识到控制温度的功率管理是至关重要的。事实上，英特尔在5月份突然宣布，它已经放弃了两款新的台式机/服务器计算机芯片（代号为Tejas和Jayhawk）的开发，以便提前一年多将更高效的芯片技术推向市场。分析师表示，此举显示出这家全球最大的芯片制造商是多么渴望减少其芯片产生的热量。英特尔提高芯片速度的方法开始需要昂贵而嘈杂的计算机冷却系统。 存在关于计算设备中的功率管理的大量文献，并且存在关于ad-hoc和传感器网络中的功率管理的大量文献。然而，几乎所有这些文献都集中在电源管理以节省能源，而不是电源管理以降低温度。温度和能量是不同的物理实体，具有完全不同的性质。简单地说，如果移动终端中的处理器超过其能量限制，则电池会耗尽，但如果移动终端超过其热阈值，则处理器会耗尽。随着设备功耗呈指数级增长，以及ad-hoc和传感器网络变得越来越普遍，管理电源以降低温度的需求将变得越来越重要。我们建议从温度的角度重新审视电源管理问题，以更好地理解管理电源以节省能源和管理电源以最大限度地降低温度之间的差异。我们计划从设备内的速度缩放问题和ad-hoc网络中的路由问题开始。预计该项目将产生新的优化技术和分析结果，这将是有用的温度效率的协议，为大规模的ad-hoc和传感器网络的设计。这项工作将是一项跨学科的联合努力，涉及具有在线算法设计以及网络协议设计和开发专业知识的研究人员。进一步预计，该项目将为学生提供一个独特的机会， 尝试新的思维方式，为这类新兴的网络设计重要的参数。
