The localization accuracy of the conventional Three-Dimensional (3D) node localization algorithm based on Received Signal Strength (RSS) is restricted by the random signal strength fluctuation caused by the irregular propagation environments. In this paper, the authors propose an improved localization algorithm based on a differential RSS distance estimation algorithm to minimize the influence of the path loss exponent error. Furthermore, considering the influence of Degree Of Irregularity (DOI), they propose a new radio model and obtain numerically the relation between DOI and the variation of signal transmission ranges.
