In wireless sensor networks (WSN) research area, node localization is one of the most important techniques. An improved Centroid localization algorithm is analyzed and an improved Centroid algorithm with selective anchor node localization algorithm (CSA) for WSN will proposed in this paper. The key point of the algorithm is the most discrepant estimation nodes are selected by the nearest reference anchor node around a distance unknown node. The triangle centroid and the polygon centroid are employed to calculate the coordinates of the estimation nodes to improve node locating precision. MATLAB simulation illustrate that the algorithm is valid and feasible.
