摘要
对网格化监测定位的传感器节点优化部署进行研究,提出了最大定位无缝覆盖的概念和问题,证明了正三角形、正方形、正六边形布站方式下满足最大定位无缝覆盖时的布站距离,并结合网格化传感器节点部署几何精度因子(GDOP)分析,提出了基于地理信息系统(GIS)的传感器节点优化部署策略及整体方案。通过在实际部署中应用该策略,较好地实现了城市复杂环境下网格化监测定位传感器节点最优化部署。
The optimized deployment of sensor nodes for grid monitoring and positioning is studied.The concept and problem of maximum coverage seamless coverage are proposed,and it is proved that the layout distance when the maximum positioning seamless coverage is satisfied under the regular triangle,square,regular hexagon layout.Combining with the analysis of the geometric accuracy factor(GDOP)of gridded sensor node deployment,a GIS-based sensor node optimization deployment strategy and overall plan are proposed.By applying this strategy in actual deployment,the optimal deployment of grid-based monitoring and positioning sensor nodes in a complex urban environment is better achieved.
