Abstract

A methodology is presented for the development of a power management configuration, based on a microcontroller, for use in autonomous low-power systems. First, the work presents an overview of the different approaches in the literature about the appropriate considerations towards evaluating power consumed by different operations in such systems, and then proposes a new design procedure. A case study is implemented on the basis of the proposed methodology, by using conventional hardware (microcontroller, modules) in a typical application. The power consumption behavior of this case study is explored by real experimental powerconsumption measurements. All the above steps form a methodology which is proposed as a general approach to power management design of low-power autonomous nodes, as usually is needed in most wireless sensor networks based on energy harvesting.
