Example Embodiment

[0090]Example 1:

[0091]Such asimage 3 As shown, the specific process of data interaction between different nodes is as follows:

[0092]The routing node R in a certain logical area of ​​the DTN network is in the monitoring state, waiting for the automatic access of the source node S1 and the source node S2 for data transmission, and the Bundle service of the source node S1 or the source node S2 for data transmission When the module 11 has a Bundle message packet to be sent, the serial port convergence layer module 12 first generates a control packet with the ID number of the local routing node and sends it to the underwater acoustic communication module 2 through the serial port, and the protocol module 21 in the underwater acoustic communication module 2 controls this The packet is encapsulated into an underwater acoustic protocol data packet, and then encoded and modulated by the modem module 22, and finally transmitted to the underwater acoustic channel by the transmitting module 23,...

Example Embodiment

[0093]Example 2:

[0094]Such asFigure 4As shown, in the underwater acoustic wireless local area network, when the source node S1 sending data and the routing node R receiving data are communicating on the successfully established link, if the source node S2 sending data passes through this period of time Sending a control packet to initiate the link establishment process with the routing node R will interrupt the communication link between the source node S1 and the routing node R, and then the source node S1 needs to compete for access to the routing node R again.

Abstract

The invention provides an underwater acoustic wireless networking method and device based on a DTN architecture. The method comprises the following steps: initializing an underwater acoustic DTN network; establishing an inter-node communication link of each logic area of the underwater acoustic DTN network to realize data transmission between different nodes; generating a routing table between thenodes, and selecting an optimal path for successfully transmitting the Bundle message to the destination node; and generating and transmitting a serial port data packet, obtaining a region name and an ID number of a destination node, generating a Bundle message packet, and providing a storage and transmission mechanism. The DTN module is well compatible with the underwater acoustic communicationmodule, can be well applied to an underwater communication environment, and is high in data transmission efficiency.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic communication, and in particular relates to an underwater acoustic wireless networking method and device based on a DTN architecture. Background technique [0002] The research on underwater acoustic network started in the 1990s. AOSNs in the United States proposed the concept of "underwater acoustic network", and conducted experiments with the "Seaweb" and "sea network" programs to prove the feasibility of using acoustics for underwater networking communication. , derived a series of underwater acoustic network plans and applications, such as the US "Offshore Continuous Underwater Surveillance Network PLUSNet" project, the "Deep Sea Siren Tactical Paging DSTP" system, and the recent "Maritime Combat Real-time Communication Timely" project; Europe's SUNRISE Projects; the JANUS underwater communication standard formulated by NATO are all developed around the construction of a robust and...
