Based on the hardware of CC2430/1 wireless sensor network positioning system,an algorithm is putforward by using Gauss distribution function and batch estimation fusion theory.First the Gauss analysis model RSSI is applied,and low probability event RSSI values are removed.Then,high probability event RSSI values are calculated with the single-sensor batch estimation fusion theory and are used as final RSSI.Experiments show that the algorithm can improve the positioning accuracy up to 0.5 meters.
