Measuring energy footprint of software features

Abstract—With the proliferation of Software systems and
the rise of paradigms such the Internet of Things, Cyber-
Physical Systems and Smart Cities to name a few, the energy
consumed by software applications is emerging as a major
concern. Hence, it has become vital that software engineers
have a better understanding of the energy consumed by the
code they write. At software level, work so far has focused on
measuring the energy consumption at function and application
level. In this paper, we propose a novel approach to measure
energy consumption at a feature level, cross-cutting multiple
functions, classes and systems. We argue the importance of such
measurement and the new insight it provides to non-traditional
stakeholders such as service providers. We then demonstrate,
using an experiment, how the measurement can be done with a
combination of tools, namely our program slicing tool (PORBS)
and energy measurement tool (Jolinar).
