引入RSSI指纹抖动量的室内定位改进算法
Improved Indoor Localization Algorithm of Introducing RSSI Fingerprints Jittering
摘要
Abstract
In order to improve the accuracy of indoor localization using Received Signal Strength Indicator ( RSSI ) fingerprints, a new method of introducing the jittering of RSSI fingerprints is proposed, which defines the calculating method of the RSSI fingerprints jittering,and applies it to measure the distance between the reference tags and tags that are being tracked,and computes the RSSI fingerprints of the virtual tags. Test results show that the average localization accuracy is about 0. 35 m ~0. 88 m higher by the improved algorithm than RFFP,and 0. 38 m ~0. 94 m higher than LANDMARC while the time-consuming increases by only 1% and 12% respectively.关键词
