IoT-Based Energy Harvesting and Future Research Trends in Wireless Sensor Networks

Abstract

The more technology advances, the extra benefits to the public and devices that connect to the internet have increased as well, commonly known as internet of things (IoT). The battery lifespan of these devices rises with technical concerns where an alternative to traditional energy attainment is needed. As the way forward, wireless sensor networks (WSNs) and IoT are tested to be used as novel energy alternatives through energy harvesting (EH). This study identifies the availability of energy by location. Similarly, it focuses on the sensor node's architecture with EH capabilities expanding to the classification of five EH techniques. It evaluates the EH developments in search of minimal resource utilization associated with WSNs. Its extensive distribution of interconnected devices is connected via the internet and other related high-tech innovations. Finally, it discusses the feasibility of energy storage and its potential for WSNs, paving the way for future trends and motivations.
