Historically, energy management in computer science has been predominantly treated as an activity of hardware optimization. A great deal of the effort in this area is concentrated on component activation, deactivation, and resources scheduling in order to provide a reduction of total power consumption. This study focuses on the subject of power consumption from the software developer’s point of...

Dynamic adaptation of the base stations on/off activity or transmit power, according to space and time traffic variations, are measures accepted in the most contemporary resource management approaches dedicated to improving energy efficiency of cellular access networks. Practical implementation of both measures results in changes to instantaneous base station power consumption. In this paper, e...

Location-based services have to pay careful attention to their power consumption in order not to drain the batteries of mobile phones. It is not a simple task to build low-power location-based services that can run for hours, because such services make heavy use of many power-consuming features of mobile phones. In this article we discuss the power consumption of location-based services and mob...

Energy-aware task scheduling is critical for real-time embedded systems. Although dynamic power has traditionally been a primary source of processor power consumption, leakage power is becoming increasingly important. In this paper, we present two optimal energy-aware polynomial-time algorithms for scheduling a set of tasks with release times, deadlines and precedence constraints on a single pr...

Abstract: The introduction of uncontrollable renewable energy is having a positive impact on our health, the climate, and the economy, but it is also pushing the limits of the power system. The main reason for this is that, in any power system, the generation and consumption must match each other at all times. Thus, if we want to further introduce uncontrollable generation, we need a large abil...

AbstructA direct approach to transistor sizing for minimizing the power consumption of a CMOS circuit under a delay constraint is presented. In contrast to the existing assumption that the power consumption of a static CMOS circuit is proportional to the active area of the circuit, it is shown that the power consumption is a convex function of the active area. Analytical formulation for the pow...

In information systems, it is critical to reduce the total electrical power consumption of computers and networks in order to realize the digital ecosystems and the green IT technologies. The extended power consumption laxity-based (EPCLB) algorithm is proposed to select a server in a set of servers so as to not only satisfy deadline constraint but also reduce the total power consumption of ser...

Ceramic gas sensors used for measuring ambient air quality have features suitable for practical applications such as healthcare and air quality management, but have a major drawback-large power consumption to preheat the sensor for accurate measurements. In this paper; the adaptive preheating duration control (APC) method is proposed to reduce the power consumption of ambient air quality sensor...

The ability to measure the energy consumed by cloud infrastructure is a crucial step towards the development of energy efficiency policies in the cloud infrastructure. There are hardware-based and software-based methods of measuring energy usage in cloud infrastructure. However, most hardware-based energy measurement methods measure the energy consumed system-wide - including the energy lost in...
