Abstract-- To complete the real-time collection of urban environment information, the study constructs a smart urban environment monitoring system based on the ZigBee wireless network. The fundamental monitoring network and the remote receiving terminal make up the system. The streetlights serve as pathways, and the taxis serve as nodes, in the basic monitoring network. After dynamically structuring the network, each node is given an address, which serves as the network's sole identification. The system then runs a simulation experiment to ensure that it can meet the needs and sends the collected data to the selected terminal in the form of a message, as specified. The smart city infrastructure could be inspired by the sensors arranged through the ZigBee wireless network. People could benefit from a wiser and more comfortable society as a result of the network.
