The utility model relates to a non line of sight path discrimination device used for wireless sensor node positioning and a working method thereof, belonging to the technical field of communication signal processing. The anchor nodes are divided into four groups for each group and sub groups using AML and LS joint position estimation method, a residual detection equation, the equation is used to update the initial packet, eventually get beyond the path combination. The new grouping and sub grouping method and the new grouping updating method can be used to identify the line of sight signals with very low computational complexity, which can meet the requirements of low energy consumption and high positioning accuracy.
