摘要
在地面无线传感器网络中,一般是假设所有的传感器节点都处于同一个二维平面上,而对于水下传感器网络来说,由于传感器节点可以部署在不同的海深,因此也就构建了一个三维网络。论文针对水下三维传感器网络的部署问题进行研究,分析了常用的空间填充多面体在空间部署中的特性,给出了各种空间填充多面体在空间中的部署模式,进一步提出了在保持完全覆盖和连通的前提下各个节点部署坐标之间的相互关系,并对截顶正八面体的部署方式进行了仿真。为三维无线传感器网络节点部署提供了方法。
For the on land wireless sensor network,it is often considered that all the sensors are in one plane.But for the under-water wireless sensor network,the sensors can be deployed at different depths.So the three dimensional sensor networks are built.To solve the problem of the node deployment in three dimensional under-water wireless sensor networks,the character in the space deployment of the space-filling polyhedron is analyzed.And the deployment modes of each space-filling polyhedron are provided.This method can calculate the relationship of the coordinate of each node in promise of both coverage and connectivity.In the end,the deployment of the truncated octahedron is chosen to be simulated.This method provides an effective way to solve the problem of the node deployment in three dimensional under-water wireless sensor networks.
