Abstract of the Article
Being powered by the batteries that are limited in their capacity is one of the main restrictions of
mobile devices. Further enhancement of their characteristics and mobile Internet mounting speed
incite the growth of user’s demands. Users request the most sophisticated applications to work
rapidly and being available all the time. Thus, availability of mobile devices should not be
decreased by inefficient energy consumption.
This paper presents the approach which is able to decrease the power consumption on mobile
gadgets. The core idea lies in migrating parts of the application’s functionality to remote servers in
order to reduce energy consumption on the mobile device. Heavy-loaded code blocks are extracted
from mobile apps and transferred to server-side applications. It is expected that, if energy spent on
client-server communication is less than power needed to execute the task on phone or tablet;
battery life time can be extended on the mobile device. Depending on the amount of data, available
internet speed, and cloud computing capabilities, systems performance can also be affected.
Experiments are conducted on migrating three Android applications to the cloud. The paper
describes the migration approach, shows changes in energy consumption and demonstrates
conditions to be met, when doing energy migrations to the cloud, successfully.
