| Abstract: | This paper proposes a novel intelligent estimation algorithm in Wireless Sensor Network nodes location based on Free Search, which converts parameter estimation to on-line optimization of nonlinear function and estimates the coordinates of senor nodes using the Free Search optimization. Compared to the least-squares estimation algorithms, the localization accuracy has been increased significantly, which has been verified by the simulation results. |
