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.
