Cooperative Localization with Mobile AUVs for SparseUnderwater Sensor Networks
摘要
Abstract
Efficient localization of underwater sensor networks with sparse deployment sensor nodes is still an active topic for researchers.One cooperative localization mechanism for 3D underwater sensor networks is proposed,which derives greater benefit from accurate position ability of multiple AUVs to help un-localized sensor nodes to be localized.The proposed cooperative mechanism introduces a recursive localization estimation method using anchor nodes and mobile AUVs together,and then deduces Least Square based position estimation equation in 2D horizontal plane projected from 3D region.Simulation results verify that the proposed cooperative localization algorithm can improve localization efficiency in terms of localization coverage ratio,normalization localization error and average confidence factor.关键词
