Power efficiency analysis of multimedia secured mobile applications

Multimedia mobile applications using wireless communication and security services 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 processor must provide in order to prolong battery lifetime of a mobile device. The multitude and complexity of devices that implement a large spectrum of multimedia and wireless protocols require closer evaluation and understanding in respect to energy efficiency. As there is very little analysis on the relationship between multimedia encoding algorithms and security encryption algorithms 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 processor and memory power consumption, wireless communication power consumption and video and sound interface power consumption.
