Abstract— In sensor networks the device localization is an interesting topic due to its relationship with routing and energy consumption. We propose a scheme to perform localization, based on the estimation of the power received by only two bea- cons placed in known positions. By starting from the received powers, eventually averaged on a given window to counteract in- terference and fading, the actual distance between the sensor and the beacons is derived and the position obtained by means of tri- angulation. The paper shows the effectiveness of this approach in different environments, by including the possible disturbance due to fading channels and sensor mobility.
