Abstract: Based on the method of hierarchical tree and the spatialtemporal correlation theory, we studied the problem of fast processing of big data and the fast application of optimization algorithm in the agricultural Internet of things, and proposed an improved hybrid hierarchical bounding box tree and collision detection algorithm. The experimental results show that the optimization algorithm has a certain promotion value  in the field of agricultural Internet of things.

Key words: hybrid hierarchical bounding box,  Internet of things, spatialtemporal correlation, collision detection algorithm, optimization algorithm
