摘要：
According to the application of range-free measurement for wireless sensor networks (WSNs), a novel localization algorithm of nodes in based on iterative centroid estimation is proposed in the paper. First, we derive the centroid of the plane enclosed by the current connected beacon nodes as well as the received signal strength (RSSI) between target and beacon nodes. Then, we replace the farthest beacon node from the target node with the centroid node we derive in order to narrow the area of the plane enclosed by the connected beacon nodes and improve the location accuracy through multiple iterations. Judging from the simulation results, the proposed algorithm presents decent results of all indications and is thus eligible for localization in WSNs.
