摘要：Node scheduling is one of the key issues in research of internet of things, while the 3D scheduling algorithm of nodes oriented the underground space near surface is the application foundation of the wireless sensor network (WSN). It brought up the research of methods for more efficient coverage of wireless sensor network node, built the node scheduling algorithm oriented underground space with self-adaptability and multi-precision constraints. According to the final results of analysis and simulation test of the network structure, self-adaptability, energy consumption, coverage connectivity and other aspects of the algorithm, it can effectively address the scheduling issue of nodes of the underground space near surface, and it can also provide theoretical guidance and practical evidence for the monitoring of soil environment, ITS (Intelligent Transportation Systerm), and other underground targets. The algorithm is of great practical value
