Abstract : Power management is a very vast topic and the solution spans around hardware and software approaches. The power efficiency of IoT low-power devices becomes an important component of modern communication environments since it is very costly or impossible to replace or change device batteries in deployed environments. Energy management in sensor networks is an open challenge to researchers Hence, this article is investigated the power management solutions introduced in various literature. A detailed investigation of energy harvesting-based techniques and network-based solutions for efficient utilization of available energy is explored. The paper also highlights the recent advancement in technologies to improve battery life by adding low power components, circuitry, and low power communication protocols such as ZigBee, RPL, wirelessHART, Bluetooth low energy, and LoRAWAN. The analysis drawn from the investigation is the combination of the power provisioning approach with power control-based solutions are the best suited for designing power-efficient schemes.
