摘要
本文给出了一种基于定位信息和图论的分布式传感器网络定位模型。用Delaunay三角剖分描述节点实体和它们的关系以及结点之间的信息传递和融合;用Voronoi图定义节点覆盖的区域。该模型可以克服现有系统基于固定的底层结构定位的缺点,大大提高传感器网络的灵活性。在所提到的模型基础上进行了网络的自组织仿真,结果良好。
Based on the location information and graph theory, a distributed sensor network model is introduced. The relationship between data transmission and fusion between nodes are described with the Delaunay triangulation. And the Voronoi diagrams are used in the description of the coverage region of nodes. With the model, the disadvantages of the existing location systems based on a fixed infrastructure can be overcome; and the self-development simulation experiments of the networks are done. The results are satisfactory.
