摘要: The Magnetic Induction (MI) communication techniques have enabled or enhanced many wireless applications in the indoor environments where line-of-sight (LOS) links usually do not exist. position information of each device such complex environment can also be derived by same MI systems without additional hardware infrastructure. However, while signals penetrate most transmission media significant attenuation and phase shifting, conductive objects (e.g., metallic pipelines, beams, human bodies) still dramatically influence signals, which cause estimation errors MI-based localization. To date, no analysis/solution has been provided to address problem. In this paper, an environment-aware localization mechanism is proposed for networks non-LOS preinstalled infrastructures. First, on network investigated. Then based analysis, a joint conductive-object tomography algorithm developed estimate devices as well distribution objects. simulation evaluation shows accurately localize floor plan with multiple walls obstructions.
