Green Software Using Aspect Orientation For Cyber-Physical-Systems

Green Computing emphasizes the need for reducing the environmental impact of systems by reducing their energy waste. Nowadays IT systems as Cyber-Physical-Systems (CPS) are composed by many physical entities interconnected and working together. Therefore, saving energy in these systems implies to be aware of the energy in all the software modules that compose the system running in every device. Since all modules could collaborate in making a software system more energy efficient, these green-ness attributes may have a crosscutting nature. Aspect-Oriented techniques could be applied specifically for energy saving in this kind of systems with specific requirements. We discuss the characteristics that a framework to allow injecting green aspects to CPS both at design and at runtime would have to provide.
