Environment-aware localization for wireless sensor networks using magnetic induction

摘要: Abstract The Magnetic Induction (MI) communication techniques can enable or enhance many wireless applications in the complex environments where line-of-sight (LOS) links do not exist. critical position information of each device also be derived by same MI systems without additional hardware infrastructure. However, while signals penetrate most transmission media significant attenuation phase shifting, obstacles with high conductivity still influence signal propagation, which incurs positioning errors MI-based localization. To address such challenge, this paper develops an environment-aware localization technique for sensor networks amount high-conductive obstructions. First, system architecture and channel is introduced. capability realized analyzing unique response gathered node. Then, a joint environment sensing algorithm developed to estimated network as well distribution objects. Finally, performance proposed solution validated through both computer simulations real-world experiments.
