Application-Level Power Management in Pervasive Computing Systems:a Case Study

摘要

In this paper we propose an application-level power con- sumption 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.
