Low Power Design Techniques for IoT Devices

As Internet of Things (IoT) devices become more common, there is a greater need for energy-efficient solutions that make devices more self-sufficient and battery life longer. Internet of Things (IoT) devices must be able to use the least amount of power possible in order to work as efficiently as possible and require less upkeep. This study looks at many things, including software, hardware, and system-level optimizations. It gives an overview of low-power design methods mainly for IoT devices. This research shows a low-power, low-cost RISC-V processor with a mixed encryption accelerator that is designed for use in the Internet of Things (IoT). It is quick and safe for this processor to protect and decrypt data sent between IoT devices. Ultra-low-power microcontrollers, sensors that use less energy and low-power transmission protocols are all seen as tools that could be used to make technology that is aware of power. This research looks into how dynamic power management techniques, power-aware scheduling algorithms, and duty cycling can be used to make the best use of system resources and meet application needs. Internet of Things devices can also switch between active and inactive states smoothly by using sleep modes and wake-up methods. Adaptive power management systems change how devices work based on things like human behavior, load, and environmental conditions in order to get the most energyefficient results. These strategies make it easier for Internet of Things (IoT) systems to be set up successfully in a wide range of businesses.
