Abstract

The invention discloses a three-dimensional wireless sensor network clustering coverage method, a terminal device and a storage medium. The method includes: generating node clusters for each node in the three-dimensional wireless sensor network according to preset rules; and according to the initial cluster head, and The initial coordinate information and energy information of each node in each node cluster, calculate the offset of each node cluster, and update the initial cluster head according to the offset; when the offset reaches the preset threshold, stop updating, and Record the target coordinate information of the updated cluster head; use the node corresponding to the target coordinate information as the target cluster head, and transmit data through the target cluster head. The present invention selects the initial cluster head from the three-dimensional wireless sensor network through a preset algorithm, and screens out the target cluster head in consideration of the distribution density of the nodes, and performs data transmission through the target cluster head, so that on the basis of considering the energy of the cluster head, Avoid premature death of cluster heads.

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 ...
