While the feature sizes of recent Complementary Metal Oxid Semiconductor (CMOS) devices decrease the influence of static power prevails their energy consumption. Thus, power savings that benefit from Dynamic Frequency and Voltage Scaling (DVFS) are diminishing and temporal shutdown of cores or other microchip components become more worthwhile. A consequence of powering off unused parts of a chi...

Nowadays energy consumption problem is a major issue for data centers. The energy consumption increases significantly along with its CPU frequency getting higher. With Dynamic Voltage and Frequency Scaling (DVFS) techniques, CPU could be set to a suitable working frequency during the running time according to the workload. On the other side, reducing frequency implies that more servers will be ...

In old age, the complex relation of food consumption with energy and nutrient requirements finds expression in both single and multiple nutritional problems. Addressing conditions affecting intake -- either from foods or from supplements -- endogenous production, bioefficacy and/or requirements can benefit nutritional health in old age through balancing requirements and supply.

The Wireless Sensor Network (WSN) is the collection of large no of low-cost micro-sensors which are used to collect and send various kinds of messages. Energy is the most important aspect of the WSNs because it determines the aliveness of wireless sensor node. In this paper we propose Hierarchical Energy Efficient Clustering Algorithm (HEEC) for WSN. HEEC achieves good performance in terms of r...

As the level of human interaction with robotic systems increases, robot mobility becomes more important. Two wheeled robots offer higher levels of mobility and manoeuvrability when compared to their four wheeled counterparts with the ability to turn on the spot and easily negotiate tight corners. Whilst the stabilisation of two wheeled platforms has been well studied, there is no published rese...

In the stable election protocol, sensors are randomly deployed in the region without considering the balancing energy consumption of normal nodes and advanced nodes. If a normal node that has been selected as a cluster head is located far away from the base station, it will affect the efficiency of the network due to its early death. In this paper, an improved energy efficient routing protocol ...

Nowadays, more and more increasingly hard computations are performed in challenging fields like weather forecasting, oil and gas exploration, and cryptanalysis. Many of such computations can be implemented using a computer cluster with a large number of servers. Incoming computation requests are then, via a so-called load balancing policy, distributed over the servers to ensure optimal performa...

ODMAC (On-Demand Media Access Control) is a recently proposed MAC protocol designed to support individual duty cycles for Energy Harvesting Wireless Sensor Networks (EH-WSNs). Individual duty cycles are vital for EH-WSNs, because they allow nodes to adapt their energy consumption to the ever-changing environmental energy sources. In this paper, we present an improved and extended version of ODM...

One of the main goals of recent developments in the Smart Grid area is to increase the use of renewable energy sources. These sources are characterized by energy fluctuations that might lead to energy imbalances and congestions in the electricity grid. Exploiting inherent flexibilities, which exist in both energy production and consumption, is the key to solving these problems. Flexibilities ca...

Sensor nodes usually propagate data packets in a multihop fashion. However, in the most of routing protocols, the optimal routes are likely to be used for the following transmissions. As a result, the optimal routes tend to accelerate the energy depletion of nodes, especially in low-power networks, which are noisy and error-prone. ADHOP is a low overhead routing algorithm which can adapt to dyn...
