A Comprehensive Approach to Power Management in Embedded Systems

Abstract

Power management is addressed in the context of embedded systems from energy-aware design to energy-efficient implementation. A set of mechanisms specifically conceived for this scenario is proposed, including a power management API defined at the level of user-visible system components, the infrastructure necessary to implement that API (namely, battery monitoring, accounting, autosuspend, and autoresume), an energy-event propagation mechanism based on Petri nets and implemented with aspect-oriented programming techniques, and an autonomous power manager build upon the proposed API and infrastructure. These mechanisms are illustrated and evaluated using realistic wireless sensor network cases that sustain comparisons with other proposals at each of the considered levels. As a result, this paper has its main contribution on the introduction of a comprehensive and systematic way to deal with power management issues in resource-constrained, battery-operated systems.

“…Both proposed energy harvesting circuits have been integrated to the power management mechanism of EPOS [16]. EPOS is a component-based operating system for embedded applications, which is provided with a task-scheduler.…”

A survey of techniques for improving energy efficiency in embedded computing systems

“…2. Using low power modes, called power mode management (PMM) [25,27,32,37,56,73,[75][76][77][78][79][80][81]. Note that this is also sometimes referred to as 'dynamic power management'.…”

Energy-Efficient Ultrasonic Water Level Detection System with Dual-Target Monitoring

“…Although there are efforts to utilize a self-powered water level sensor to harvest energy from liquid-solid contact [ 20 , 21 , 22 ], it is inapplicable to non-contact sensors. Advanced power management technique in programming level is studied using power management application programming interfaces (APIs) [ 23 ]. Although the advanced power management system of API method [ 23 ] and integrated circuits using Maximum Power Point Tracker chip [ 24 ] method are considerable to manage the system power, these approaches are possibly limited to specific data processing or control design.…”
