无线传感器网络SL-n迭代定位算法
SL-n iterative localization algorithm in wireless sensor networks
摘要
Abstract
To compensate for the lackness of robusmess caused by MMSE(minimum mean square estimation) in overall situation in wireless sensor network iterative multilateration algorithm, a new estimation algorithm called SL-n were proposed.Firstly all samples were obtained using trilateration or partial MMSE from every combination of n reference nodes which belonged to some blind node, then the location of the blind node were estimated.Simulation experiments show that the proposed SL-n algorithm outperforms MMSE method in overall situation and can reduce the position error sufficiently when the reference error is large.关键词
