Aiming at the problem of energy consumption of node deployment network in three-dimensional（3 D） space

the problem of node deployment optimization under the condition of ensuring k coverage is studied

and an improved spatial Mosaic node deployment algorithm based on energy optimization is proposed.Use of the truncated octahedron as sub-unit of space mosaic for target space filling

references to the vertices on the deployment of sensor nodes to sleep and wake up in stages strategy

for the local optimum condition that maximum probably occur in the process of sleeping and wakeing up

fuse the improved artificial bee colony（ABC） algorithm for improvement

and ultimately achieve the effect that reduce the consumption of energy.
