An Intelligent Resonant Wireless Energy Distribution System for IoT Sensor Networks

[EN] Wireless power transmission (WPT) is a key enabling technology for autonomous Internet of Things (IoT) sensor networks deployed in remote or hard-to-access environments. This paper presents an intelligent resonant wireless energy distribution system that integrates power transfer, sensing, communication, and adaptive control within a unified Wireless Sensor Network (WSN) architecture. The proposed system introduces multi-role nodes capable of operating as transmitters, relays, or receivers, enabling scalable and battery-free network deployment. A parameterized analytical and simulation framework is developed to model power transfer behavior, and a functional prototype is implemented and experimentally validated. The system incorporates a rule-based adaptive control mechanism and IoT communication (MQTT/HTTP) for real-time monitoring and dynamic power regulation. Experimental results demonstrate wireless energy transfer over distances up to 35 meters under controlled conditions, supporting continuous operation of distributed sensor nodes. The proposed approach advances WPT-enabled IoT systems by providing a scalable, energy-autonomous architecture for distributed sensing applications.
