Design and Analysis of Power Optimization in Internet of Things using RFID based Energy Harvesting Mechanism

One of the major concerns in using IoT devices is life of the battery, especially in remote places where power resources are limited. By employing certain low powered sensors, the IoT devices with higher power consumption can be activated only when required. In this paper, a methodology is proposed for reducing the consumption of power in an IoT device which sends data from a RFID tag to an output file. The consumption is reduced by implementing sleep mode when, the device is not required to be active, and a wakeup signal and studying the impact it has on the power consumption. An energy harvesting device is also integrated to make the device self-sustainable.
