Abstract:A localizationalgorithmbasedonRSSIisproposed in order to solve the problem of positioning the family sheep. Combining the centroid algorithm for targetting the location with the route distance calculation,the algorithm uses the noise model to process the raw data.Theexperimentalresultsshowthatthealgorithmcanaccuratelycalculate the position coordinates and the distance path of the sheep.
