Abstract

The invention discloses a three-dimensional wireless sensor network clustering coverage method, terminal equipment and a storage medium. The method comprises the following steps: generating node clusters through various nodes in a 3D wireless sensor network according to a preset rule; and computing offset of each node cluster according to an initial cluster head, and initial coordinate informationand energy information of ach node in each node cluster, and updating the initial cluster head according to the offset; stopping updating when the offset achieves the preset threshold, and recordingtarget coordinate information located by the updated cluster head; and taking the node corresponding to the target coordinate information as the target cluster head, and performing data transmission through the target cluster head. Through the method disclosed by the invention, the initial cluster head is selected from the 3D wireless sensor network through a preset algorithm, and the target cluster head is screened out in consideration of the distribution density of the node, the data transmission is performed through the target cluster head, thereby preventing the cluster head from prematuredeath on the basis of considering the cluster head energy.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a three-dimensional wireless sensor network clustering coverage method, terminal equipment and storage media. Background technique [0002] In the existing technology, the Mean shift (mean shift) algorithm is applied in the process of wireless sensor cluster coverage to solve the problem of empty clusters in the coverage process. This method mainly makes the movable wireless sensor move towards the opposite direction with high cluster head density. Move to achieve the purpose of uniform distribution of cluster heads, and then solve the problem of empty clusters in the process of cluster coverage. However, most of the current cluster coverage algorithms are only suitable for two-dimensional plane area coverage. In addition, through low-power adaptive The clustering algorithm (LEACH, Low Energy Adaptive Clustering Hierarchy) algorithm selects the cluster head at random, and ...
