Energy Harvesting in IoT Networks for Smart City Infrastructure

Abstract

The integration of Energy Harvesting Technologies (EHTs) in Internet of Things (IoT) networks is pivotal for enhancing smart city infrastructure. This research addresses the pressing issue of energy sustainability in IoT applications, where traditional battery reliance poses significant maintenance and environmental challenges. Employing a comprehensive review of various energy harvesting methods—including solar, kinetic, and thermal energy—this study outlines their applicability in urban settings. The methodology involves analyzing existing literature and case studies to evaluate the efficiency and effectiveness of these technologies in real-world scenarios. Key findings indicate that energy harvesting can significantly reduce operational costs by eliminating the need for frequent battery replacements, thereby promoting a more sustainable urban environment. Furthermore, the results suggest that implementing these technologies can enhance the longevity and reliability of IoT devices, making them self-sufficient and reducing their carbon footprint. The implications for the field are profound, as adopting energy harvesting solutions could lead to smarter, more resilient cities capable of meeting future energy demands without compromising environmental integrity.
