Title: Research on Positioning Accuracy of ZigBee Indoor Positioning System Optimization Algorithm
Abstract: Indoor wireless location system based on ZigBee development becomes a hot spot,because the use of wireless communications,it can save cost,and more convenient to use.At the same time,based on the location and orientation of the Received Signal Strength Indication(RSSI) vulnerable to a number of factors,making ranging and positioning errors are relatively large.Positioning system for indoor-environment-wide is presented in this paper,make a way to access the RSSI(median filtering and mean filtering)and positioning optimization algorithm(based on maximum likelihood estimation method for optimizing algorithm of weighted to get location),through a combination of two methods,which improves positioning accuracy.At the same time,LabVIEW software is used to development PC.
