A Power Saving Hybrid Technique for IoT

Abstract

Most IoT applications usually contain a battery inside, which provides good mobility for the system, but also limits lifetime of the application in general. A lot of work concentrated on power saving algorithms for software, and hardware solutions to provide better results. The proposed solution uses a hybrid technique that enables the IoT system to save power by installing a secondary low current microcontroller to put sensors and other devices in sleep mode, and depending on the IoT device's application, it will be awakened by a needed trigger that is tuned according to the application (such as certain sensors readings, or time based trigger). This will provide high system flexibility.

Adaptive piecewise linear model for class C rectifier design

“…With emerging trends in Internet of Things (IoT) for smart city applications, the devices are required to provide digital identification, sensing capability while consuming a small fraction of power. Besides the research efforts to minimize the energy consumption for battery time extension, 4,5 the idea of harvesting the ambient RF energy is of interest for researchers around the world due to the possibility of all time harvesting in coverage areas of wireless communication. The harvested energy can be used either directly for the device's functionality 6 or for battery/super capacitor charging 7 .…”
