ABSTRACT
The continuous expansion of modern battery powered devices with complex and resource hungry feature sets have shown that battery life time does not scale according to their evolution. The problem of supporting extended battery life time has been drawing a lot of attention in recent years, especially for mobile communication systems. Besides the advances in power efficiency for hardware components, another emerging dimension has been opened by energy-aware software components. In this paper we briefly survey some of the most recent directions in supporting power efficiency for battery powered devices. In order to promote power-aware application, we propose an open power efficiency framework which addresses some of the shortcomings of existing approaches towards power aware software. We describe both generic and specific concepts of the proposed framework together with a new evaluation dimension at both lower and higher layers. Last but not least, we define the architecture of the framework which we aim to realize and evaluate through several battery powered mobile systems.
