Energy efficiency combined SW techniques on mobiles Android OS

Energy efficiency in mobile computing is one of the most challenges and especially in the wireless data transmission involved in mobile applications. It have attracted much attention from mobile device manufacturers, OS provider's, mobile application programmers and as well network operators. There are many “areas” where such energy improvement can be made but at some extra costs from other side. Nowadays one of major target of this research area is to develop cross OS solutions while trying to maintain the device performance. If we look at the smartphone system-level power management solutions from software architecture point of view, the proposed solutions for now can be implemented on OS part, as middleware or application level or combination between any of them. Main contribution of this paper is to analyze and show the methodologies used in nowadays Android OS for different kind of Smartphone's HW that could be even personalized in case of good programming knowledge.
