Investigation for Software Power Consumption of Code Refactoring Techniques

Code refactoring technique focuses on enhancing the maintainability of software to extend its lifetime. However, there are other efforts to improve software qualities like performance or reliability as well as maintainability by using code refactoring techniques. Recently, as low-power software has become one of the critical issues in mobile environments, developing energyefficient software through code refactoring becomes an important one. This paper aims to investigate whether the existing refactoring techniques can support energy-efficient software generation or not. The refactored codes generated by the existing techniques can consume more power than original codes because they did not consider the power consumption in their refactoring processes. This paper analyzes the power consumption to investigate the energy efficiency of M. Fowler’s refactoring techniques. Our analysis result can provide useful information about energy-efficient refactoring techniques to software engineers, and support the development of software that has high maintainability and good energy efficiency.
