Requester-Aware Power Reduction

by Yung-Hsiang Lu, Luca Benini, Giovanni De Micheli - In Proceedings of the International Symposium on System Synthesis , 2000
"... Typically, power reduction is conducted by hardware techniques, such as varying clock frequencies and/or supply voltages. However, hardware devices consume power to serve the requests from software programs. Consequently, it is essential to consider software for power reduction. This paper proposes ..."

Power-Aware Routing in Mobile Ad Hoc Networks

by Mike Woo, Suresh Singh, C. S. Raghavendra , 1998
"... In this paper we present a case for using new power-aware metrics for determining routes in wireless ad hoc networks. We present five different metrics based on battery power consumption at nodes. We show that using these metrics in a shortest-cost routing algorithm reduces the cost/packet of rout ..."

Operating-system directed power reduction

by Yung-hsiang Lu, Luca Benini, Giovanni De Micheli - in Proceedings of the International Symposium on Low Power Electronics and Design (ISLPED , 2000
"... This paper presents a new approach for power reduction by taking a global, software-centric view. It analyzes the sources of power consumption: tasks that require services from hardware components. When a component is not used by any task, it can enter a sleeping state to save power. Operating syste ..."

The Case for Energy-Proportional Computing

by Luiz André Barroso, Urs Hölzle
"... Energy-proportional designs would enable large energy savings in servers, potentially doubling their efficiency in real-life use. Achieving energy proportionality will require significant improvements in the energy usage profile of every system component, particularly the memory and disk subsystems. ..."
Abstract - Cited by 469 (2 self) - Add to MetaCart
. Energy efficiency, a new focus for general-purpose computing, has been a major technology driver in the mobile and embedded areas for some time. Earlier work emphasized extending battery life, but it has since expanded to include peak power reduction because thermal constraints began to limit further CPU

The design of an acquisitional query processor for sensor networks

by Samuel Madden, Michael J. Franklin, Joseph M. Hellerstein, Wei Hong - In SIGMOD , 2003
"... We discuss the design of an acquisitional query processor for data collection in sensor networks. Acquisitional issues are those that pertain to where, when, and how often data is physically acquired (sampled) and delivered to query processing operators. By focusing on the locations and costs of acq ..."
