[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0032] Example 1

[0033] Figure 1 This is a flowchart of a networking method for underwater wireless optical communication provided in Embodiment 1 of the present invention. This embodiment is applicable to underwater wireless optical communication networking. The method can be executed by an underwater wireless optical communication networking device, which can be implemented in software and / or hardware, optionally through an electronic device, such as a mobile terminal, PC, or server. Specifically, it includes the following steps:

[0034] S110 allows for setting multiple optical communication densities.

[0035] Wherein, the optical communication density is the number of optical communication nodes contained in a unit volume of water area; the optical communication node has a defined beam range, which is determined by the beam field of view and the transmission distance. In this embodiment, the optical communication node includes a light-emitting module and a receiving module. The light-emitting module emits light within a certain beam range, and the receiving module receives light emitted by other optical communication nodes. The beam field of view can be a cone, and the transmission distance can be understood as the farthest transmission distance of the light emitted by the light-emitting module. For example, Figure 2 This is an example diagram of the optical communication node in this embodiment, such as... Figure 2 As shown, optical communication nodes 1-5 all have a certain beam range, and each optical communication node has corresponding location information and orientation information.

[0036] In this embodiment, to determine the relationship between optical communication density and connectivity, it is first necessary to set multiple optical communication densities, the unit of which can be (numbers / cubic meter). For example, the multiple optical communication densities can be set to positive integers between 5 and 20, and then the connectivity corresponding to each optical communication density is determined.

[0037] S120, for each optical communication density, multiple virtual optical communication networks are randomly set up in the virtual water area according to the optical communication density.

[0038] Each virtual optical communication network includes the location and orientation information of each optical communication node. The virtual water area can be a virtual water area of ​​a certain volume arbitrarily set during the simulation phase. In this embodiment, in order to simulate the constantly changing underwater environment, the location and orientation of each optical communication node need to be randomly set according to the optical communication density in the virtual water area to obtain multiple virtual optical communication networks.

[0039] Specifically, the required number of optical communication nodes is first determined based on the volume and optical communication density of the virtual water area. For each of these nodes, a randomized position and orientation are assigned, resulting in multiple virtual optical communication networks. Each network includes the specified number of optical communication nodes, with their positions and orientations randomly arranged.

[0040] S130, determine the relationship between optical communication density and connectivity based on the location and orientation information of each optical communication node.

[0041] In this context, connectivity can be understood as the proportion of connected pseudo-optical communication networks among multiple virtual optical communication networks corresponding to optical communication density. In this embodiment, optical communication density and connectivity are directly proportional; that is, the higher the optical communication density, the higher the connectivity.

[0042] Specifically, the method for determining the relationship between optical communication density and connectivity based on the location and orientation information of each optical communication node can be as follows: determine the connectivity of each virtual optical communication network based on the location and orientation information of each optical communication node; and determine the relationship between optical communication density and connectivity based on the connectivity of the virtual optical communication network.

[0043] Connectivity includes whether a link is connected or not. The connectivity of a virtual optical communication network can be determined by the ratio of the number of optical communication nodes in the longest connected link in the virtual optical communication network to the total number of optical communication nodes.

[0044] Specifically, the method for determining the connectivity of each virtual optical communication network based on the location and orientation information of each optical communication node can be as follows: determine the longest connected link in the virtual optical communication network based on the location and orientation information of each optical communication node; determine the proportion of optical communication nodes included in the longest connected link in the optical communication network; if the proportion exceeds a set threshold, the connectivity of the virtual optical communication network is considered connected.

[0045] The connected link can be a unidirectional or bidirectional link. If the connected link is unidirectional, then every pair of adjacent optical communication nodes in the connected link is connected at least along the direction of connection of the link; if the connected link is bidirectional, then every pair of adjacent optical communication nodes in the connected link is bidirectionally connected. The longest connected link can be understood as the connected link containing the most optical communication nodes. The threshold can be set by the user, for example, it can be any value between 0.8 and 1. In this embodiment, when the proportion of optical communication nodes in the longest connected link of the virtual optical communication network exceeds the set threshold, the connectivity of the virtual optical communication network is considered connected.

[0046] Specifically, the method for determining the longest connected link in the virtual optical communication network based on the location and orientation information of each optical communication node can be: determining the connectivity between any two optical communication nodes; and determining the longest connected link in the virtual optical communication network based on the connectivity between any two optical communication nodes.

[0047] The connectivity between any two optical communication nodes includes unidirectional and / or bidirectional connectivity. Unidirectional connectivity can be understood as one optical communication node being within the beam range of another optical communication node, but the other optical communication node not being within the beam range of the first node. Bidirectional connectivity can be understood as one optical communication node being within the beam range of another optical communication node, and the other optical communication node also being within the beam range of the first node. For example, Figure 3a This is an example diagram of unidirectional communication between optical communication nodes, such as... Figure 3a As shown, optical communication node B is within the beam range of optical communication node A, but optical communication node A is not within the beam range of optical communication node B. Therefore, optical communication node B is connected to optical communication node A, but optical communication node A cannot connect to optical communication node B. This is a one-way communication from A to B. Figure 3b This is an example diagram of bidirectional communication between optical communication nodes, such as... Figure 3b As shown, if optical communication node B is within the beam range of optical communication node A, and optical communication node A is within the beam range of optical communication node B, then optical communication node B is connected to optical communication node A, and optical communication node A is connected to optical communication node B. This is bidirectional communication between A and B. For example... Figure 3c An example diagram of multi-hop communication for optical communication nodes, such as... Figure 3c As shown, the communication link is A→B→C→D→A.

[0048] In this embodiment, after determining the connectivity between any two optical communication nodes, a connection link containing the most optical communication nodes is found in the virtual optical communication network based on the connectivity between any two optical communication nodes, and this connection link is taken as the longest connection link.

[0049] Specifically, the method for determining the relationship between optical communication density and connectivity rate based on the connectivity of a virtual optical communication network can be as follows: determine the proportion of virtual optical communication networks with connectivity among multiple groups of virtual optical communication networks; and determine the proportion as the connectivity rate corresponding to the optical communication density.

[0050] The proportion of connected virtual optical communication networks can be understood as the ratio between the number of connected virtual optical communication networks and the number of virtual optical communication networks corresponding to the optical communication density. In this embodiment, for multiple sets of virtual optical communication networks at each optical communication density, the proportion of connected virtual optical communication networks is used as the connectivity rate corresponding to that optical communication density, thereby obtaining the relationship between optical communication density and connectivity rate. For example, Figure 4 This is an example diagram illustrating the relationship between optical communication density and connectivity in the embodiments, such as... Figure 4 As shown, connectivity is directly proportional to optical communication density.

[0051] S140 is a network for underwater wireless optical communication based on the relationship between optical communication density and connectivity.

[0052] In this context, underwater wireless optical communication networking can be understood as deploying a certain number of optical communication nodes in the target water area.

[0053] Specifically, the networking method for underwater wireless optical communication based on the relationship between optical communication density and connectivity can be as follows: obtain the volume of the target water area and the target connectivity; determine the target number based on the relationship between optical communication density and connectivity, the target connectivity, and the volume of the target water area; set up the target number of optical communication nodes in the target water area to obtain the target optical communication network.

[0054] The target connectivity rate can be selected based on the actual optical communication needs of the target water area. A higher connectivity rate can be selected if the communication requirements are high, and a lower connectivity rate can be selected if the communication requirements are low. The target number is the number of optical communication nodes required.

[0055] The method for determining the number of targets based on the relationship between optical communication density and connectivity, the target connectivity, and the volume of the target water region can be as follows: determine the target optical communication density based on the relationship between optical communication density and connectivity and the target connectivity; determine the number of targets based on the target optical communication density and the volume of the target water region.

[0056] In this embodiment, the target optical communication density corresponding to the target connectivity is first determined based on the relationship between optical communication density and connectivity. Then, the target optical communication density is multiplied by the volume of the target water area to obtain the target quantity.

[0057] In this embodiment, after determining the target number, the target number of optical communication nodes are placed in the target water area to obtain the target optical communication network. The longest connected link of the target optical communication network varies with the underwater environment, and the overall connectivity rate can reach the target connectivity rate.

[0058] The technical solution of this embodiment sets multiple optical communication densities; wherein, the optical communication density is the number of optical communication nodes contained in a unit volume of water area; the optical communication nodes have a set beam range, which is determined by the beam field of view and transmission distance; for each optical communication density, multiple sets of virtual optical communication networks are randomly set in the virtual water area according to the optical communication density; wherein, each set of virtual optical communication networks includes the location information and orientation information of each optical communication node; the relationship between optical communication density and connectivity is determined based on the location information and orientation information of each optical communication node; and underwater wireless optical communication networking is performed based on the relationship between optical communication density and connectivity. The underwater wireless optical communication networking method provided by this embodiment first determines the relationship between optical communication density and connectivity, and then performs underwater wireless optical communication networking based on the relationship between optical communication density and connectivity, which can improve the network coverage and data transmission rate during underwater communication, reduce exploration time and cost, and improve exploration efficiency.
