Title:
UNDERWATER NETWORKING METHOD USING MAGNETIC-FIELD COMMUNICATIONS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/199455
Kind Code:
A1
Abstract:
The present invention relates to an underwater networking method using a magnetic-field communications system. The underwater networking method using a magnetic-field communications system comprising a plurality of mobile relay nodes and a magnetic-field communications server comprises: a step in which the magnetic-field communications server obtains location information on a transmission node, a reception node, and the plurality of mobile relay nodes; a step for selecting N (a natural number greater than or equal to 1) mobile relay nodes required for relay by using information on the distance between the transmission node and the reception node; a step for configuring the locations of the N mobile relay nodes, moving the N mobile relay nodes to the configured locations, and aligning the coil axes of the transmission node, the reception node, and the plurality of mobile relay nodes; and a step in which the transmission node transmits data to the reception node via the selected mobile relay nodes. According to the present invention, long-distance and high-speed transmission can be stably provided by adopting a waveguide transmission scheme in magnetic-field communications advantageously reducing propagation delay time and enabling the establishment of a network at lost costs. In addition, the performance of the magnetic-field communications can be improved as a result of effectively utilizing mobile relay nodes by merging location information obtained by means of a magnetic-field positioning technique and the waveguide transmission scheme.
