Abstract

The invention relates to a three-dimensional wireless sensor network coverage method and system. In the system, a target space is filled by taking a truncated octahedron as a filling subunit; arranging a sensor node at each overlapped vertex of any two adjacent truncated octahedrons, and arranging a node at each vertex, except the overlapped vertex, of all truncated octahedrons; taking the sensing radius as a coverage radius, and judging whether the target space is covered by k or not according to the coverage radiuses of all nodes; if the target space is not covered by k, progressively increasing deployment nodes in the truncated octahedron one by one, and after the target space is covered by k, performing dormancy on part of the nodes according to sensing contribution and decision parameters of the nodes; and an improved artificial bee colony awakening algorithm is adopted to perform staged awakening, so that the energy consumption of the nodes can be reduced by performing dormancy and awakening on all the nodes while the target space is ensured to be covered by k, and the service life of the nodes is prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a three-dimensional wireless sensor network coverage method and system. Background technique [0002] Node deployment is a very important part in wireless sensor networks (WSNs) and plays an irreplaceable role. It has an important impact on energy problems, path optimization problems and positioning problems in WSNs. How to extend the service life of the network while ensuring network coverage and improving the fault tolerance rate of network connectivity has attracted the attention of many researchers at this stage. At present, some researchers have adopted a 3D surface coverage and connection method based on directional gradients, but due to the setting of the premise environment, it only covers the surface in the 3D environment. Some researchers have adopted a grid-based distributed energy effective k-covering multi-connectivity deployment algorithm, which co...
