| Abstract: As for the low precision of the Wi-Fi trilateral localization algorithm caused by the uneven distribution of
nodes,the paper proposes a new Wi-Fi trilateral localization algorithm based on centroid.The algorithm effectively improves
the location estimation accuracy of the measuring points by calculating the centroid of the overlapping areas of intersecting
circles.The results of data analysis and chart analysis prove that the improved Wi-Fi trilateral localization algorithm based on
centroid actually provides higher precision than the original trilateral localization algorithm. |
