摘　　要：农田通常面积广阔,地形复杂,不同区域的信号覆盖范围和信号强度存在差异。为了保证智慧农业数据的实时和准确传输,避免网络资源浪费,提出了基于FFT算法的智慧农业通信节点部署方法。利用布尔感知模型计算目标点的覆盖程度,调节传感器节点位置,获得最大化监控区域的覆盖率。通过信息接收能耗和发送能耗,计算出中继节点和动作节点间通信能量消耗。使用FFT算法计算网络虚拟力函数模型,优化虚拟力矩阵,完成智慧农业通信节点部署。仿真实验结果表明,所提方法的通信节点部署效果好,网络覆盖面积合理,能减少能量消耗,延长网络使用寿命。Typically,farmlands have vast areas and complex terrain,with varying signal coverage and intensity across different regions.To ensure the real-time and accurate transmission of smart agricultural data and avoid network resource waste,this paper put forward a method for smart agricultural communication node deployment based on FFT algorithm.Firstly,a Boolean perception model was used to calculate the coverage rate of target points,and adjust the position of sensor nodes,thus achieving maximum coverage rate of the monitoring area.Secondly,the communication energy consumption between relay nodes and action nodes was calculated through the energy consumption of information reception and transmission.Moreover,a FFT algorithm was adopted to solve the virtual force function model of the network and optimize the virtual force matrix.Finally,the deployment of smart agricultural communication nodes was completed.Simulation results show that the proposed method has good deployment effect for communication nodes and reasonable coverage area.Meanwhile,the method can reduce energy consumption and extend network service life.
