Towards Multiple Sources for Energy Harvesting in Wireless Sensor Networks in Practical Applications

Abstract

For wireless sensor networks (WSNs) to continue operating, energy harvesting plays a critical role. This paper explores this topic. WSNs are essential to many applications, from industrial processes to home automation. The difficulty is in giving sensors enough power, particularly in isolated or difficult-to-reach places. A solution is found in energy harvesting, which uses vibration, heat, radio frequency, heat, and solar energy to power sensors. The wide range of uses for energy harvesting in climate change modeling, noise pollution mitigation, and environmental monitoring are examined in this paper. The emphasis now turns to real-world applications of various energy sources to improve WSN performance, with a particular emphasis on the switch from primary to rechargeable batteries. The study emphasizes how battery-free devices can lower maintenance costs and increase application possibilities. The field of energy harvesting, which includes thermal, radiofrequency, vibration, and solar energy, provides access to sustainable and priced WSNs. By elucidating the benefits of battery-free devices, this study underscores the potential to enhance WSN sustainability while simultaneously lowering operational costs. It underscores the transformative impact of energy harvesting, offering a pathway to sustainable and economically viable WSN deployments.
