Abstract :
In this paper, an improved subspace approach based on range measurement is proposed and analyzed. Through the factorization of multidimensional similarity (MDS) matrix, we derive a novel kernel subspace to estimate the coordinate of unknown mobile node in wireless sensor networks (WSN). Simulation results are included to contrast the estimator performance with general subspace method, and the performance analysis is provided.
