Sensor's localization plays a very important role in wireless sensor networks, a new sensor localization approach with Ring Overlapping Based on Received Signal Strength Indicator (ROBRSSI) using three beacons is presented. Through the designing of error transforming and the collaboration between nodes, the effect of measurement error of RSSI on localization accuracy is restrained efficaciously, the requirement of the relative position between node and beacons is reduced and the node's precise localization is achieved. Then the localization of new comer who is added into WSN to compensate for the node fail to work is studied on the basis of ROBRSSI. Simulation results show that the location accuracy is well and the localization percentage is satisfactory; the localization method of new comer in WSN is efficient, which achieves precise localization.
