Machine-to-Machine Communication (M2M) is the communications between wireless devices without human interventions. As a fundamental enabler of Internet of Things, M2M is growing fast and implemented in many areas. The number of M2M devices is expected to be extremely large in the future. In most cases they are battery driven and positioned in broad areas so that it would be costly to frequently...

Small and medium enterprises (SMES) play an important role in Taiwan’s economy. The reduction of energy costs and carbon dioxide (CO2) emissions are critical to preserving the environment. This paper uses the experimental results from 65 sites, gathered over two years since 2012, to determine how the integration of Internet communication, cloud computing technologies and a cloud energy manageme...

The wide spread use of IEEE Wireless LAN 802.11 in battery operated mobile devices introduced the need of power consumption optimization while meeting Quality-of-Service (QoS) requirements of applications connected through the wireless network. The IEEE 802.11 standard specifies a baseline power saving mechanism, hereafter referred to as standard Power Save Mode (PSM), and the IEEE 802.11e stan...

In light of recently stirred energy consumption concerns, we investigate the opportunities for power consumption reduction in Grids. Considering real life Grid traces, we note considerable fluctuations in load. We consider a peak load dimensioning strategy to derive how much servers to install in computational Grids. In lower loaded periods, there is a potential to save energy by dynamically po...

BACKGROUND AND OBJECTIVES Patients undergoing surgery for hip fracture (HF) often receive perioperative allogeneic blood transfusions (ABT) to avoid anaemia. However, concerns about the adverse effects of ABT have prompted the review of transfusion practice and the search for a safer treatment of perioperative anaemia. MATERIALS AND METHODS We prospectively investigated the effect of a blood-...

Broadcasting live digital TV to a small battery-powered handheld device is very challenging. One of the most promising technologies to provide such services is DVB-H (Digital Video Broadcasting over Handheld). Power consumption has always been one of the most crucial challenges for handheld devices. In this paper, a novel Adaptive Modulation and Coding (AMC) framework is proposed for DVB-H syst...

During the last decade mobile communications increasingly became part of people’s daily routine. Such usage raises new challenges regarding devices’ battery lifetime management when using most popular wireless access technologies, such as IEEE 802.11. This paper investigates the energy/delay trade-off of using an end-user driven power saving approach, when compared with the standard IEEE 802.11...

Energy efficiency is one of the most important attributes in sensor network protocols. In sensor nodes, communication related activities consume the major share of battery energy. Therefore, judicious choice of transmit power and frame size are very important to maximize the energy efficiency and hence the lifetime of nodes. While there have been a few recent studies on transmit power control i...
