Focusing on the accuracy of target locating in wireless sensor networks, a target locating algorithm based on curve-fitting is proposed. With least square fitting to the positions of all targets, the curve parameters of the approximate target traveling path are calculated. Moreover, more localization information is introduced to participate in target locating via piecewise curve fitting, thus erroneous factor is reduced in the process of localization. Finally, the localization and tracking of the target is realized. Test results indicate that the proposed algorithm brings higher target locating precision than general curve fitting method, thus the accuracy of target locating in wireless sensor networks can be improved effectively.

... However, the above documented methods are not suitable and accurate for the calibration of remote water measurement. Literature [8][9][10] proposes an adaptive segmented curve fitting localization algorithm based on the influence of environmental factors to enhance curve fitting accuracy. Nevertheless, this algorithm tends to overlook data points with less impact on the fitted curves, resulting in a somewhat one-sided consideration. ...
