3D-RABLC:a novel refinement algorithm based on LQI confidence for three-dimensional localization

Blog Article

A novel refinement algorithm based on LQI confidence for three-dimensional localization (3D-RABLC)was proposed.LQI confidence was obtained in terms of here the relationships between RSSI and one hop distance,LQI and packet error rate(PER),which derived from experimental data.The measured RSSI was filtered by LQI confidence.

Moreover,the RSSI with lower confidence was modified by a three-dimensional multi-hop model or a compensating refinement method.The experiment results show read more that the algorithm reduces the RSSI range error,and improves the accuracy of three-dimensional localization significantly.
