Three-dimensional Terrain Correcting for Detection of WSN Space Coverage Hole
International Journal of Grid and Distributed Computing
When wireless sensor networks using spatial random deployment, disturbed three-dimensional topography of factors can lead to the generation of the coverage hole. In order to effectively detect the coverage holes in the target area, in this paper, we propose a method for detecting space coverage holes in sensor networks based on three-dimensional terrain correction. Firstly using Delaunay triangulation subdivides network coverage and calculates the Delaunay triangle circumscribed circle,doi:10.14257/ijgdc.2016.9.8.14 fatcat:ulvb2bzy5jh4hl7yv5p73v7w5y
