Abstract

In this paper we propose an application-level power consumption modeling and optimization technique for mobile devices. The application being considered is modeled as a FSM and the power consumption figures are associated with it through current measurements on selected states, followed by the application of a linear functional model. The FSM model is then used, together with a power management policy, to extend battery lifetime while guaranteeing the execution of essential states in the application. In this paper, the methodology is applied to a specific case study, namely the fruition of multimedia content in an E-Learning scenario.
