摘要
目前大多数传感器网络部署研究主要集中在二维平面和三维全空间区域,然而,许多现实世界的应用领域是一个复杂的三维空间曲面,现有的覆盖方法不能取得较好的结果。本文研究三维空间曲面传感器网络部署方法,提出一种三维曲面多移动节点的传感器网络部署算法,采用静态节点和动态节点组成的混合传感器网络,由静态节点估算覆盖空洞的位置和面积,再通过移动节点对覆盖空洞进行依次修复。仿真结果表明,该算法的最终网络覆盖率达到了99%,比3DGA算法提高了6个百分点,比Delaunay算法提高了8.5个百分点,同时降低了网络整体能耗。
At present,most of the researches on sensor network deployment are mainly focused on two-dimensional(2D)planes and three-dimensional(3D)full-space areas.However,many real-world application fields are a complex 3D surface.The existing coverage methods cannot achieve good results.This paper studies the deployment method of 3D surface sensor networks,and proposes a 3D surface multi-mobile node sensor network deployment algorithm.A hybrid sensor network composed of static nodes and dynamic nodes is used to estimate the position and area of the coverage hole from the static nodes.The coverage holes are sequentially repaired by mobile nodes.Simulation results show that the final network coverage rate of the algorithm reaches 99%,which is 6 percentage points higher than the 3DGA algorithm and 8.5 percentage points higher than the Delaunay algorithm,while reducing overall network energy consumption.
