The paper verified the performance of all the solutions proposed in this paper by simulation considering the factors of different deployments,connectivity of network, positions of nodes and the utilizations rate of nodes.The simulations show that,the optimization pattern based on Voronoi polygon of this paper is better than deployment pattern in corresponding works,which achieved better coverage results with fewer nodes.Also,topological graph of nodes deployment network is plotted for optimization deployment models based on boundary topology.The experiment illustrates that every deployment model has a predominant advantage in a certain situation. However,when the ratio of communication radius and sensor radius is between[1.73,2),the triangle pattern based on 6-connectivity shows great superiority,and compared to the models based on 4-connectivity and 3-connectivity,the average number of nodes used reduced by 23.9%and 50.0%separately,while the efficiency of nodes reaches as high as 82.7%.
