Design of ZigBee-Based Energy Harvesting Wireless Sensor Network and Modeling of Solar Energy

Traditional wireless sensor networks rely on battery power to operate, but when the node’s energy is exhausted, the node loses its ability to operate. To enable wireless sensor networks to achieve continuous working, researchers have turned their attention to energy harvesting wireless sensor networks. The energy harvesting wireless sensor network has the advantages of energy renewable, low maintenance cost, etc., and can achieve permanent use of nodes to a certain extent. However, the energy collected by nodes in such networks will change with the change of environment and time, so the survival of energy-gathering wireless sensor networks in environmental detection needs further study and research. In view of the above problems, we designed a solar energy harvesting wireless sensor network in this paper, and designed energy harvesting and energy consumption related experiments to record the energy and network characteristics under different weather and time, collected under different conditions, and model the solar energy collected under different circumstances, so as to provide basic data for the further research of network reliability and other characteristics.
