本文研究多层移动传感网络结构下,移动聚集节点Sink的覆盖优化控制策略。首先对相关研究工作进行简单介绍,然后介绍一种新型的多层移动传感网络结构,并基于Delaunay三角剖分的Sink节点移动策略完成对传感节点S的定位。继而以S节点为产生点进行有界Voronoi划分,提出一种Sink节点的覆盖优化控制策略,优化S节点的分布,消除覆盖盲区,提高网络的覆盖性能。
This paper studies the coverage optimization control strategy of mobile aggregation node Sink under the multi-layer mobile sensing network structure. First of all, the related research work is briefly introduced. Then a new multi-layer mobile sensing network structure is introduced, and the localization of sensing node S is completed based on Delaunay triangulation Sink node movement strategy. Then, the Voronoi partition of S-node is taken as the generating point. A new Sink node’s coverage optimization control strategy is proposed to optimize the distribution of S-nodes, eliminate the blind spots and improve the network coverage.
