Abstract
Communications Technology (ICT) devices has become
more user-friendly, which raised the problem of power
dissipation across the globe and computer systems are
one among them. This emerging issue of power
dissipation has imposed a very significant issue on the
system and software design. The concept of ̳green
computing‘ gaining popularity and is being considered
as one of the most promising technology by the
designers of Information Technology (IT) industry,
which demonstrate the environmentally responsible way
to reduce the power consumption and maximize the
energy efficiency. In this paper, we have proposed an
energy sustainable framework of the power schemes for
operating systems to reduce the power consumption by
computer systems and presented a Green Power tool
(GP tool). This tool is designed using JAVA technology,
which requires least configuration to make a decision
for reducing the power consumption and proposed Swift
mode algorithm, allows users to input the working time
of their choice then after the end of time algorithm
starts detection of human activity on the computer
system.
Introduction
With the explosive growth of Information
Technology (IT), Information and Communications
Technology (ICT) devices and its computer systems
software can be considered as a high performance
computing devices. If the system operator leaves these
computer systems running without any work then the
systems will not only consume the energy but also
produce enough amount of heat. This is not good for the
environment as energy consumption puts a lot of
pressure to generate more energy production and
produced heat is responsible for the greenhouse gas
effect, which have various adverse effects on the human
body [1]. According to the prediction from the United
States Department of Energy, the energy use by the
computer systems in commercial sector is expected to
grow by 2.9% per annum on an average between 1998
and 2020 [2]. The green computing also known as
sustainable computing [3] and focus on two important
areas such as energy-efficient computing and power
management [4]. Green computing also represents an
intelligent and environment friendly way that
transforms the existing engineering and various other
disciplines to implement this concept into its processes,
products and systems while considering the effects on
environment as well as on human.
Proposed Framework of Power Scheme
This section discusses the proposed framework of
power schemes for Windows Operating Systems, which
is developed as a tool known as Green Power tool (GP
tool). This framework is shown in Fig. 1 and starts its
functioning with the execution of power saver module.
This power saver module starts as a local services of
the Windows Operating System and prompts the user to
input the approximate time also known as login
duration of working on the computer system. As soon
as the user inputs the value of login duration this value
is utilized by three major modules of proposed
framework that is power-saver main window, duration
and calculate CPU usage. Here, power saver-main
window represents the Graphical User Interface (GUI)
of proposed GP tool whereas further two modules are
very much concerned about implementation of the
proposed algorithms to minimize the power
consumption by the computer systems. These
algorithms are implemented as two different modes
known as: 1) Swift Mode and 2) Exhaustive Mode and
are part of GUI as shown in Fig. 2. These two modes
are very different in their functioning.
Conclusions
In this paper, we have proposed an energy-
sustainable framework for the power schemes of
operating systems to minimize the energy consumption
by computer systems. The proposed framework is a part
of GP Tool. The main objective of this tool is to
structure concepts, strategies, and activities to design an
energy-sustainable power scheme. This framework is
useful for both the desktops and laptops. The unique
characteristic of this tool is that it required minimal
input and calculations for saving energy.
