摘　　要：针对山地霜冻灾害的预测问题,提出了基于Voronoi图的无线传感网山地霜冻灾害预测算法。首先,通过在山体上部署若干无线传感器节点,形成山体的Voronoi网络覆盖;其次,根据无线网络采集的环境数据计算山体各部的成霜概率,并根据成霜概率的大小划分Voronoi区域的成霜等级;最后,对达到预警阈值的Voronoi区域向农户发出灾害预警,以便及时进行人工干预,从而降低霜冻灾害对农业生产的影响。For the problem of mountain frost disaster prediction, a wireless sensor network algorithm based on Voronoi diagram is proposed. First, by deploying several wireless sensor nodes on the mountain, the Voronoi network coverage of the mountain is formed. Secondly, the frost-forming probability of each part of the mountain was calculated according to the environmental data collected by the wireless network, and the frost-forming grade of Voronoi region was determined according to the frost-forming probability. Finally, the Voronoi region that has reached the frost warning threshold is sent to farmers for timely manual intervention to reduce the impact of frost disaster on agricultural production.
