Distributed data query is the core of distributed database management system, and query optimization algorithm is the key technology in query processing. From the perspective of energy efficiency, the article optimizes and analyzes the data query algorithm of WSNs. On the one hand, the node with the highest remaining energy is selected from the network nodes as the query node, that is, the dynamic rotation mechanism of the query node makes the energy consumption in the network balanced, thereby prolonging the life cycle of the network; on the other hand, a fuzzy matching query makes the process of data processing by the node is simplified, and the energy consumption of the node is reduced from the aspect of data processing. The simulation results show that the improved algorithm can find the optimal query execution plan in a short time, speed up the query, and improve the query efficiency.
