Abstract

This paper develops a model for operating system level power management in cyber physical systems. The core part is a transducing mechanism, forming physical inputs into functional state sequences. Each functional state transition then is allowed to switch in between power management plans. A power management plan is modeled as a directed graph over power states and functional jobs together with timing conditions. Different optimization problems for designing these plans according to scheduling requirements, and for maximizing energy savings under both constrained management complexity and constrained supply voltage stability are presented.
