Accurate Path-Loss Exponent Correcting Location Method

摘要：

　　A lot of studies have been done in Received Signal Strength Indication (RSSI) based indoor location for wireless sensor network,and most of them assume that the Path-Loss Exponent (PLE) is a fixed value already known or can be measured by experiment.However,PLE is usually not a fixed value.Analysis and simulation indicate that the PLE has much effect on the distance estimation error under the commonly used log-normal shadowing model.Based on the existing positioning algorithm,we proposed a method dynamically correcting the value of PLE,using the environmental information of reference node.Finally,experiments have been implemented,and results show that the improved algorithm has higher positioning accuracy and good environmental adaptability.
