A view on power efficiency of multimedia mobile applications

Abstract

Multimedia applications running on mobile devices and using wireless networks become more and more demanding with respect to processing speed and power consumption. Power saving is one of the most important feature that network interface and mobile CPU must provide in order to prolong battery lifetime. The multitude and complexity of devices that implement a large spectrum of multimedia and wireless protocols requires closer evaluation and understanding in respect to power efficiency. As there is very little analysis on the relationship between multimedia applications and their power profile in the context of mobile wireless devices, we investigate the landscape of multimedia communication efficiency methods. The proposed evaluation scenarios address CPU power consumption, wireless communication power consumption and video and sound interface power consumption. © Springer Science+Business Media B.V. 2010.
