摘要
本文以无线传感器网络节点动态部署为主要研究对象,在Delaunay三角剖分获得网络节点邻接关系的基础上,提出了改进Delaunay三角剖分的虚拟力算法,通过建立节点最佳邻接关系的选择策略,改善了网络虚拟势场,减小了节点虚拟力的计算规模。仿真结果表明,与原算法相比,改进算法能够快速地扩散密集节点,具有更优的扩散效率。
In this paper, the dynamic deployment of wireless sensor network nodes is the main research object. Based on the adjacency relationship of network nodes in Delaunay triangulation, the improved Delaunay triangulation for virtual force algorithm is proposed. It developsthe selection strategy of the best adjacent nodes, improves the virtual potential fieldof the network and reduces the calculation scale of the virtual force on the node. The simulation results show that the improved algorithm compared with the original algorithmcan effectively spread the close nodes and has better diffusivity.
