Cover Story: Wireless rechargeable sensor networks (WRSNs) are critical for monitoring and data collection in large-scale dynamic environments. Energy autonomy of sensor nodes is crucial for their sustained operation. This paper surveys state-of-the-art technologies in on-demand energy provisioning for large-scale WRSNs. We explore energy harvesting techniques, storage solutions, and management strategies tailored to resource-constrained environments. The survey categorizes literature based on energy sources and discusses advances in storage. We also investigate management techniques that balance consumption and harvesting to optimize network performance. This paper identifies opportunities and challenges in energy provisioning for WRSNs and provides insights for future innovations in sustainable sensor networks, which are critical for smart city solutions.
