designing wireless sensor networks should meet appropriate parameters such as quality of service (qos) defined by different users. the variable physical conditions of the environment, processing and transmission power limitations and limited communication capabilities are the most important obstacles that influence qos parameters such as throughput, delay, reliability and network lifetime. the ...

In this paper we present a “Framework for Power Aware Remote Processing ‘‘ to minimize the energy consumption of mobile devices transparently. The main difference to remote processing frameworks already published consists in a novel integrated dynamic Power Estimation Unit. This is an adaptive power consumption estimator, which estimates the energy consumption of sojiware and system components....

− A stepwise driving method was used for reducing the AC power consumption in a TFT-LCD. The AC power takes the largest portion of the total power consumption of a TFT-LCD. Experimental results confirmed that the AC power saving efficiency reached up to 75% when a 5-stepwise driving with each step time of 2μ sec was applied to a 14.1 inchdiagonal XGA TFT-LCD. The second largest component of pow...

This paper demonstrates a first-order, linear power estimation model that uses performance counters to estimate run-time CPU and memory power consumption of the Intel PXA255 processor. Our model uses a set of power weights that map hardware performance counter values to processor and memory power consumption. Power weights are derived offline once per processor voltage and frequency configurati...

In order to make maximum use of the EV (electric vehicle) battery, evaluating the remaining battery capacity and the power consumption is important. Evaluation method of the remaining battery capacity with accuracy has been proposed. Moreover, the evaluation method of the power consumption for traveling has been proposed. However, the power consumption for vehicle-mounted air-conditioner is 30%...

Smartphones are mobile devices that travel with their owners and provide increasingly powerful services. The software implementing these services must conserve battery power since smartphones may operate for days without being recharged. It is hard, however, to design smartphone software that minimizes power consumption. For example, multiple layers of abstractions and middleware sit between an...

the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

This paper describes a novel method for the bi-directional transformation between the power consumption patterns of appliances and human living activities. We have been proposing a demand-side energy management system that aims to cut down the peak power consumption and save the electric energy in a household while keeping user’s quality of life based on the plan of electricity use and the dyna...

Low power consumption is a primary concern in many CMOS image-sensor applications. As the resolution of these sensors has increased while maintaining or increasing their frame rates, A/D conversion has become the dominant component of power consumption [1]. Conventional image compression can help reduce the readout rate [2] (and hence its power consumption), but cannot reduce the A/D conversion...

With the development of cloud computing, high energy consumption issue has attracted more and more attentions recently. To achieve the goal of energy conservation, accurately measuring the power consumption of distributed resource is of significant importance. Conventional power models can only provide fine-grained power measurement for physical devices instead of virtualized resources. In this...
