Coverage Blind Spot Detection Methods for Wireless Sensing Network Based on Voronoi Diagram
It the exposure of holes is less,errors are more likely to occur when detecting network coverage,which affects the detection effect of blind areas.Therefore,a blind area detection method for wireless sensor networks based on Voronoi diagram is proposed.The coverage of the wireless sensor network is estimated according to the node distribution relationship.Under the guidance of Voronoi dia-gram,the covered area is excluded,and the uncovered wireless sensor network holes with detection conditions are obtained.The expo-sure degree and node energy of the network holes are calculated and input into the particle swarm separator as feature samples.Accord-ing to the output results of the classifier,the blind area detection of wireless sensor network coverage is realized.The simulation results show that the detection time of the proposed method is less than 0.2 s under different coverage blind areas,the detection energy con-sumption under different node numbers is less than 20 J,and the coverage blind area difference under different hole center distances is 0.24,which verifies that the proposed method has a good coverage blind area detection effect in wireless sensor networks.
