Simple and efficient location algorithms are of great research significance to Wireless Sensor Networks (WSNs) systems. In this paper, main factors of position error in the Centroid location algorithm are analysed, and then a Furthermost Beacon (FB) location algorithm is presented. In the range of the communication radius of the nodes to be located, the algorithm estimates four beacon nodes or more with highest distribution degree around the unknown nodes. A group of experiments have been conducted and the results of the experiments have demonstrated the superior performance of the proposed algorithm.
