In wireless sensor network (WSN), sensors are small, inexpensive, and computable. However, they are limited in power, memory, and computational capacities. A large number of tiny sensors are usually deployed randomly to monitor one or more phenomena to collect and process the sensed data, and to send the data back to the sink. Many literatures focus on developing power-saving protocols. In addi...

In this paper, we introduced the basic principles of energy saving generation dispatching, generated sorting table and implementation processes, implemented energy-saving generation dispatching optimal electric power industry structure and layout. From the terms of the pilot provinces, energy-saving generation dispatching pilots achieved remarkable results. The article proposed full process ene...

839 All Rights Reserved © 2013 IJARCET Abstract Wireless hosts are usually powered by batteries which provide a limited amount of energy. Therefore, techniques to reduce energy consumption are of interest. One way to conserve energy is to use power saving mechanisms. Power saving mechanisms allow a node to enter a doze state by powering off its wireless network interface when deemed reasonable....

A power-saving management for OLTP applications has become an important task for user budgets and datacenter operations. This paper presents a novel power-saving method for multiple disk drives based on knowledge of OLTP application behaviors. We report detail analysis of power consumption of disk drives and I/O characteristics of OLTP application. We then show experimental and simulation resul...

In this paper, an average consumed energy for a unit data transmission in analyzed in frequency-agile cognitive radios. The average energy consumed by a random access protocol operated in a channel using a whole system bandwidth is compared with that operated in frequency-separated channels, which results in an energy saving ratio. The energy saving ratio quantitatively evaluates an energy savi...

One way to conserve energy is to use power saving mechanisms. Power saving mechanisms allows a node to enter a doze state by powering off its wireless network interface when deemed reasonable. Another alternative is to use power control sc...
