Underwater communication apparatus using seamless DTN Delay Tolerant Network protocol and method thereof

摘要

The present invention relates to an underwater communication apparatus using a seamless DTN protocol that enables seamless underwater communication between divers in underwater using a seamless Delay Tolerant Network (DTN) protocol, and a method for underwater communication. . The underwater communication device using the seamless DTN protocol according to the present invention is an underwater communication device mounted on a plurality of divers and constitutes a diver network (DN), which is connected to a lower data link layer to interface with an external device. Providing a data link abstract layer; And a DTN function that stores and retransmits the transmitted data in a buffer to perform DTN function for underwater communication, and forms a network topology that forms and manages a DN topology based on underwater MANET. The management unit, the environment information collection and management unit for collecting and managing the environment information by periodically analyzing the packets received through the overhearing of multiple communication media, the environment for storing the environment information collected and managed Selecting the data link layer through the machine learning based on the surrounding situation information collected and stored in the information storage unit, the surrounding situation information collection and management unit and the surrounding situation information storage unit, and establishing an operation policy And an S-DTN layer including an operation unit.
