Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for determining a data transmission path of an underwater network, including steps S100 to S400:
S100, determining an initial node and a destination node from network nodes, and acquiring first depth information of the initial node.
It should be noted that, the underwater network includes a plurality of network nodes, for example, an underwater network routing network, where the network nodes are wireless sensor nodes, and the network nodes are randomly distributed, and before determining a transmission path, the underwater network may be initialized, for example, parameters such as initializing node energy, a communication radius, local depth information (distance between the network node and the water surface), and establishing a routing information table of each node; alternatively, the routing information table may store H-indices of neighboring nodes of the node. Optionally, the first depth information characterizes a distance between the initial node and the water surface, that is, local depth information of the initial node, which can be obtained by the depth sensing module, and other nodes are similar.
Alternatively, the network nodes of the underwater network may be classified into three types, the first being a source node, the second being an intermediate node, and the third being a destination node. The source node is a starting node for forwarding data, the intermediate node is a common node for forwarding data, the destination node is used for receiving the data of the common node and carrying out data transmission and communication with the land base station, the source node is a starting point of the data transmission, and the destination node is an end point of the data transmission. It should be noted that, the initial node is the current node, and the initial node needs to determine the normal node of the next transmission, so the initial node may be the source node or the normal node.
S200, acquiring adjacent nodes of the initial node and second depth information of the adjacent nodes, and taking the adjacent nodes with the second depth information smaller than the first depth information as first adjacent nodes.
It should be noted that the second depth information represents a distance between the neighboring node and the water surface, that is, local depth information of the neighboring node; the neighboring nodes of the initial node are network nodes located within a first communication range of the initial node.
Optionally, the step S200 of acquiring neighboring nodes of the initial node includes steps S210-S220:
s210, acquiring a first communication range of the initial node.
Alternatively, for example, the first communication range may be a sphere of a predetermined radius (denoted as a first radius). It should be noted that, each network node only needs to transmit the neighbor information in the first communication range covered by the network node, so as to minimize the overhead of the topology information of the underwater network.
S220, when the initial node does not have the previous node, acquiring a network node in the first communication range as the initial node;
Or when the initial node has the last node, determining a transmission range according to the connection line direction of the last node and the initial node and the preset distance, and determining the adjacent node according to the transmission range, the first communication range and the network node.
Optionally, when the initial node is a source node, the initial node has no previous node, and a network node in the first communication range is acquired as the initial node.
When the initial node is a common node, the node is provided with the previous node, and the transmission range is determined according to the connection line direction between the previous node and the initial node and the preset distance. It should be noted that the transmission range may be a sphere with a preset radius (denoted as a second radius), and the second radius may be a preset value or a distance between the previous node and the initial node. Then, the neighboring node is determined according to the transmission range, the first communication range and the network node, as described in steps S230-S240.
Optionally, in step S200, a neighboring node having the second depth information smaller than the first depth information is used as the first neighboring node, including steps S230-S270:
S230, determining a first area and a second area according to the transmission range and the first communication range.
S240, taking the network node of the first area and the network node of the second area as adjacent nodes.
The first area is an area where the transmission range intersects the first communication range, and the second area is an area where the transmission range does not intersect the first communication range. Optionally, the network node of the first area and the network node of the second area are used as neighboring nodes, and are divided into two parts, namely, the neighboring nodes of the first area and the neighboring nodes of the second area.
S250, when the second depth information of the adjacent nodes of the first area is smaller than the first depth information, the adjacent nodes of the first area are used as the first adjacent nodes.
In the embodiment of the invention, when at least one neighboring node in the neighboring nodes of the first area satisfies that the second depth information is smaller than the first depth information, the neighboring node of the first area satisfying the condition is taken as the first neighboring node. It should be noted that, using the neighboring node of the first area as the first neighboring node is equivalent to the second area is beneficial to further improving the transmission speed and efficiency.
And S260, otherwise, when the second depth information of the adjacent nodes of the second area is smaller than the first depth information, taking the adjacent nodes of the second area as the first adjacent nodes.
In the embodiment of the invention, when all adjacent nodes in the first area are greater than or equal to the first depth information and when at least one adjacent node in the second area meets the condition that the second depth information is smaller than the first depth information, the adjacent node in the second area meeting the condition is taken as the first adjacent node.
S270, when the second depth information of the adjacent node of the first area and the second depth information of the adjacent node of the second area are both greater than or equal to the first depth information, that is, neither the first area nor the second area has the first neighbor node, the previous node is used as a new initial node at this time, for example, when the initial node is a common node, the previous node may be the previous common node or the source node, and then the step of acquiring the first depth information of the initial node is returned, that is, the first depth information of the initial node is acquired in the step S100 is returned until the first neighbor node can be determined finally.
S300, acquiring an H index of a first neighbor node, and determining the first neighbor node with the H index meeting a preset condition as a transmission node.
It should be noted that, the H index represents that a preset number of second neighbor nodes in all second neighbor nodes of the first neighbor node have at least a preset number of third neighbor nodes, for example, when the H index of the first neighbor node is 5 (i.e., the preset number is 5), it represents that 5 second neighbor nodes in all second neighbor nodes of the first neighbor node have at least 5 third neighbor nodes; it can be understood that the third neighbor node is a neighbor node of the second neighbor node, and the determination methods of the second neighbor node and the third neighbor node are similar to those of the first neighbor node and will not be described again.
Optionally, the preset condition includes a maximum value in the H index and less than the maximum value in the H index. For example, the H indexes of the first neighbor nodes are 5, 6, 7 and 8 respectively, and then the maximum value in the H indexes refers to 8, and the first neighbor node corresponding to 8 is determined as the transmission node; when the first area and the second area of the initial node do not have the first neighbor node, for example, in the case of step S270, for example, when the initial node is an A1 node, the first neighbor node includes an A2 node with an H index of 8 and an A3 node with an H index of 7, the A1 node selects the A2 node as a transmission node at the beginning, but neither the first area nor the second area of the A2 node has the first neighbor node, at this time, the previous node of the A2 node, that is, the A1 node is taken as a new initial node, and finally the A1 node selects an A3 node with an H index smaller than the maximum H index and closest to the maximum value of the maximum H indexes, that is, corresponding to the H index of 7, as a new initial node to determine the next transmission node.
It should be noted that, regarding the neighboring node whose second depth information is smaller than the first depth information as the first neighboring node, then calculating the H index of the first neighboring node and determining the transmission node and the subsequent forwarding data, selecting the next-hop node through the depth information may make the whole routing process have no cycle, so all nodes do not need to determine whether the received information has been accepted or forwarded, thereby improving the routing utilization, and since the "next-hop node" of each node must be located above its own level, it may be ensured that the data can be transmitted from the source node to the destination node in the water.
S400, determining a data transmission path according to the transmission node and the destination node.
Optionally, step S400 includes steps S410-S430:
s410, acquiring a second communication range of the transmission node.
The first communication range is similar to the first communication range and will not be described again.
S420, when the destination node is located in the second communication range, determining that the data transmission path comprises the transmission node and the destination node.
Alternatively, when the destination node is located in the second communication range, the data may be directly transmitted to the destination node, so that it is determined that the data transmission path includes the transmission node and the destination node, that is, from the transmission node to the destination node. Note that, the node before the transmission node may be the initial node (the new initial node newly determined in step S100) and may be included in the data transmission path as well.
S430, when the destination node is located outside the second communication range, adding the transmission node into the node set and using the node set as a new initial node, and returning to the step of obtaining the first depth information of the initial node until the destination node is located in the second communication range, and determining a data transmission path according to the node set and the destination node.
Optionally, when the destination node is located outside the second communication range, the data may not be directly transmitted to the destination node, so that the next common node needs to be further determined, the transmission node is added into the node set to be saved, and the transmission node is used as a new initial node, and the step of obtaining the first depth information of the initial node is returned, that is, the step S100 is returned until the destination node is located in the second communication range, and at this time, the data transmission path is determined according to all the transmission nodes and the destination node in the node set. Likewise, the node preceding the transmission node initially saved to the node set may be the initial node (the new initial node newly determined in step S100) and may be included in the data transmission path as well.
The embodiment of the invention fuses the underwater network based on the multi-hop routing protocol with the H index, fully utilizes the thought of the H index, and finally combines the ultra-large scale underwater network, so that redundancy can be well balanced, redundancy can be reduced, redundant information can be utilized, an optimal data transmission path can be determined, routing cost can be reduced, network resources can be saved to the greatest extent, the survival time of nodes and the network can be prolonged, the utilization rate and the success rate of routing can be improved, and the success rate and the efficiency of data transmission can be improved.
