In the dairy cattle farming management positioning system,a lot of sensor nodes were arranged within the monitoring scope of wireless sensor networks to collect surrounding environmental information that will be sent out after being processed.In this study,based on the analysis of factors influencing RSSI ranging error and correction of RSSI ranging mean, the optimization algorithm of trilateration localization based on the corrected RSSI was proposed,and the Matlab simulation experiment was conducted.Finally,the localization algorithm was applied to the design of dairy cattle health monitoring and positioning systems,and the results fully met the requirements of dairy cattle health status monitoring and posi-tioning.
