An Improved Algorithm of Weighted Centroid Algorithm Based on RSSI

Abstract:

This paper presents an improved weighted centroid algorithm. The inverse of n multiply cubic distance algorithm was used as the weight, thus avoiding data swamping in the weighted centroid algorithm and preventing information loss. Under the same conditions, the improved weighted centroid algorithm is better than the traditional weighted centroid algorithm. The accuracy is improved by 7.14%.
