Deployment Method of Agricultural Communication Nodes Based on Optimizing Virtual Force Matrix
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 net-work 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 communica-tion energy consumption between relay nodes and action nodes was calculated through the energy consumption of in-formation 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 serv-ice life.
