Problems solved by technology

[0009] The DBMR protocol is also a depth-based routing protocol, but it does not use a flooding propagation mechanism, and does not generate a large amount of redundant data like the DBR protocol, resulting in excessive energy consumption. It can balance network energy consumption, but there are also routing holes Phenomenon
[0010] Due to the limited underwater transmission bandwidth, the DSVR protocol needs to embed candidate forwarding set information into the data packet when forwarding the data packet, which increases the amount of data forwarding information, and the effective utilization rate of bandwidth is low.
[0011] The above routing protocols and most of the routing mechanisms focus on how to effectively transmit the data sensed by underwater sensor nodes to the water surface, forming a single routing and forwarding direction
When the network is deployed in an uninhabited area such as the far sea away from the data center, the nodes in the network need to perform routing selection by themselves to complete the communication between the source node and the sink node. Only the single link from the underwater sensor node to the water surface gateway node is studied. The real three-dimensional sensor network has not been realized, and the situation that the sink node is an air node and other underwater sensor nodes needs to be considered. Therefore, the existing routing mechanism cannot be directly used in the ocean three-dimensional sensor network.

example 1

[0157] Example 1 Stereo monitoring of non-cooperative targets

[0158] Take the underwater node to inform the air node about the location information of the non-cooperative target as an example for analysis:

[0159] 1) Encapsulated into a data packet

[0160] Load the non-cooperative target position information into the data packet and encapsulate it according to the defined data packet format. The default forwarding direction is forwarding based on depth;

[0161] 2) Update the temporary routing table

[0162] Add the encapsulated data packet to the temporary routing table and wait for forwarding;

[0163] 3) Update the forwarding success table

[0164] After the data packet is successfully forwarded, update the forwarding success table of the node;

[0165] 4) Route forwarding

[0166] The routing and forwarding stage is mainly based on Figure 4 The process is carried out, and the data packet is forwarded from the underwater node to the water surface gateway node in...

example 2

[0170] Example 2 air-sea joint data forwarding

[0171] Continuing from the above example, the air node receives the data packet forwarded by the underwater node, extracts the information of the non-cooperative target, combines the information it perceives, determines the position of the non-cooperative target after joint judgment, and issues an attack command to the underwater node. Precision strikes against non-cooperative targets. The routing process of air nodes sending strike commands to underwater nodes:

[0172] 1) Encapsulated into a data packet

[0173] The air node encapsulates the command instruction into a data packet, and since the target node is an underwater node, it forwards it to the water surface gateway node in the form of broadcast through water wireless communication;

[0174] 2) The water surface gateway node judges and forwards

[0175] After the water surface gateway node receives the data packet, it judges whether the destination node is within its ...

Abstract

The present invention provides a routing method, device and storage medium for a marine three-dimensional sensor network, which are used to implement data routing and forwarding for the marine three-dimensional network. The ocean three-dimensional sensor network routing method includes: obtaining a data packet to be forwarded, the data packet to be forwarded carries a destination node type; judging the type of the local node, and the node type includes a water surface gateway node, an underwater sensor node and An air node; if it is judged that the local node is a water surface gateway node or an air node, the data packet to be forwarded is forwarded according to the type of the destination node; if it is judged that the local node is an underwater sensor node, then based on The depth information of the current node and the previous node performs forwarding processing on the data packet to be forwarded.

Description

technical field [0001] The invention relates to the technical field of marine networks, in particular to a routing method, device and storage medium for a marine three-dimensional sensor network. Background technique [0002] The most widely used underwater sensor network consists of surface gateway nodes and underwater sensor nodes, and the surface gateway nodes have both wireless communication and underwater acoustic communication functions. The underwater sensor nodes in the network transmit data to the surface gateway node through underwater acoustic communication. After the surface gateway node receives the data, it transmits the data to the shore base station or data center through water wireless communication. The marine three-dimensional sensor network is different from the underwater wireless sensor network. It not only includes underwater sensor nodes, water surface gateway nodes, and air nodes. It is to select forwarding in the network node. The role of routing ...
