“…The percentage of global emissions attributable to Information Systems is expected to further increase in the coming years, due to the proliferation of Internet-connected devices omnipresent in our daily lives [1] . Software never consumes energy in itself, rather its design, implementation and usage context strongly affect the energy consumed by the hardware [2,3] . So developers should be more aware of the energy consumed by these systems, and try to build energy-efficient applications that self-adapt their behavior to minimize the power consumed during their execution, i.e., develop self-greening applications.…”

Software systems have a strong impact on the energy consumption of the hardware they use. This is especially important for cyber-physical systems where power consumption strongly influences the battery life. For this reason, software developers should be more aware of the energy consumed by their systems. Moreover, software systems should be developed to adapt their behavior to minimize the energy consumed during their execution. This can be done by monitoring the usage context of the system and having runtime support to react to those changes that impact the energy footprint negatively. Although both the hardware and the software parts of cyber-physical systems can be adapted to reduce its energy consumption, this paper focuses on software adaptation. Concretely, the paper illustrates how to address the problem of developing context-aware energy-efficient applications using a Green Eco-Assistant that makes use of advanced software engineering methods, such as Dynamic Software Product Lines and Separation of Concerns. The main steps of our approach are illustrated by applying them to a cyber-physical system case study.

“…Messages can have also di erent levels of severity (e.g., trace, debug, and warning), and can be encrypted if necessary. Thus, the usage model of an FQA is de ned as the set of variables that a ect the energy consumption of that FQA, and the values that each variable can take [1,10].…”

“…There are some approaches which focus on the de nition of architectural tactics [5] and design patterns [6] driven by the energy. There are also new architectural description languages (ADLs) that include energy pro les and analysis of energy consumption [7,10]. In any case, the experimentation consists of estimating the energy consumption of the application code to analyze the e ects of applying a speci c architectural pattern or design [5,6].…”

“…Since software architects are not normally aware of the energy consumption of architectural solutions [10], our approach will automatically generate the FQA con gurations taking into account the energy consumption of the di erent variants. We also consider that the same FQA can be injected into di erent places of the application, which can have di erent usage models.…”

Functional quality attributes (FQAs) are those quality attributes that, to be satis ed, require the incorporation of additional functionality into the application architecture. By adding an FQA (e.g., security) we can improve the quality of the nal product, but there is also an increase in energy consumption. This paper proposes a solution to help the software architect to generate con gurations of FQAs whilst keeping the energy consumed by the application as low as possible. For this, a usage model is de ned for each FQA, taking into account the variables that a ect the energy consumption, and that the values of these variables change according to the part of the application where the FQA is required. We extend a Software Product Line that models a family of FQAs to incorporate the variability of the usage model and the existing frameworks that implement FQAs. We generate the most eco-e cient con guration of FQAs by selecting the framework with the most suitable characteristics according to the requirements of the application.
