Distributed range-free localization algorithm in wireless sensor networks for 3D space

  • 摘要: 为解决三维空间无线传感器网络节点定位问题,基于区域立体网格化表示的思想,提出一种分布式非测距三维定位算法3D-DRL(three-Dimensional Distributed Range-free Localization).通过对立体网格投票,选取得票值最高的所有网格的质心作为未知节点的估计位置.3D-DRL无需未知节点间相互通信,具有较小的通信开销,不依赖于锚节点比例,且对网络拓扑结构具有鲁棒性.仿真结果表明,在无线传播环境理想、未知节点通信半径 R =50m、所有节点均随机部署在100m×100m×100m三维区域的情况下,定位误差小于未知节点通信半径的8%,且通过调整VANR,能够实现所有节点的定位.
