Through analyzing the complexity of energy saving and emission reduction system in thermal power enterprise, we can find that this system affected by various elements within the system, policies and technologies in the external environment. Therefore, in order to evaluate the performance of energy saving and emission reduction in thermal power plants, both the complex nonlinear relationships am...

Minimizing the energy consumption of wireless network interfaces is crucial in the design of battery-powered mobile computing devices. The IEEE 802.11 wireless LAN specification describes a power-saving mode which allows the network interface on the mobile device to enter a sleep mode when the link is idle; periodically, the mobile device must wake up to listen to beacons from the access point ...

The “Green Computing,” is especially important and timely. As computing becomes increasingly pervasive, the energy consumption attributable to computing is climbing, despite the clarion call to action to reduce consumption and reverse greenhouse effects. A high performance-computing cluster is a set of computers gathered together and connected with the intent of merging their processing power t...

To enhance the power efficiency of broadband wireless access devices based on battery power, an adaptive power saving strategies based on cross-layer design is proposed for IEEE 802.16e sleep-mode operation. In this paper, we evaluate performance of the power-saving mechanism based on sleep mode in IEEE 802.16e mobile Worldwide Interoperability for Microwave Access (WiMAX) system, which is base...

Power is always a major concern for mobile devices. To save precious energy, mobile devices choose to stay in a low power mode by turning off their transceivers when it is not involved with transmission. However, they need to wake up to allow packets originated from them sent and those coming to them received. This presents a challenge in the distributed environment as in ad hoc networks. In th...

Unlike DSP compilation for high performance, research for low power optimisation has received little attention, although power dissipation is a critical issue for mobile devices. This paper presents an overview of power consumption models and power saving techniques for embedded DSP processors applications and evaluates their application to the Texas Instruments TMS320VC5510 Digital Signal Proc...

Energy is a scarce resource in wireless field bus systems. Strategies for power saving while coping with the application task are needed. This paper introduces the sendOnDelta-principle known from wired field bus systems. In the context of wireless sensor networks the method is analyzed and conclusions for power saving reserves are drawn.

A new alternative is proposed for reducing the power consumption of the portable (battery-powered) units operating in a mobile packet-data network. First, a short review of the current power-saving protocols is taking place. It is shown that the most common means for conserving power is the intermittent operation of the receivers (at the portable units) and a central administration authority th...

In this paper, we focus on power-aware network devices, and propose a stochastic model to evaluate their performance quantitatively. More precisely, applying the Markovian additive process (MAP) to the arrival stream for network devices, we develop a stochastic dynamic power management (DPM) model with shutdown policy. Two performance measures for power-saving and processing; steady-state power...
