[0084] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0085] One of the core concepts of the embodiments of the present invention is that the present invention obtains preset indicator information of a mobile node; determines the spatial coordinates of the mobile node mapped to a multi-dimensional virtual space based on the preset indicator information of the mobile node; and divides the segmented network to which the mobile node belongs based on the spatial coordinates of the mobile node mapped to the multi-dimensional virtual space; the present invention can more effectively manage and optimize network resources, reduce network congestion, and improve data transmission efficiency and overall network performance by dividing the segmented network to which the mobile node belongs in the multi-dimensional virtual space; the present invention can divide the segmented network to which the mobile node belongs in real time, thereby ensuring efficient communication paths and network stability.

[0086] Reference Figure 1 , shows a flowchart of the steps of a method for network node attribution in a segmented network provided by an embodiment of the present invention, the network node includes a segment node and a mobile node, the method is applied to the segment node, and the method may specifically include the following steps:

[0087] Step 101: Obtain preset indicator information of a mobile node.

[0088] In the embodiment of the present invention, the preset indicator information is used to indicate a series of parameters set by the mobile node in the mobile ad hoc network or other dynamic network environment, which may include the following aspects, such as connection quality indicators: such as signal strength, link stability, data transmission rate, etc.; security indicators: such as encryption strength, authentication mechanism, intrusion detection; service quality indicators: such as delay, jitter, packet loss rate; mobility indicators: such as node speed, direction, predicted path, etc.; network load indicators: current network bandwidth usage, traffic distribution between nodes, etc. The specific one is not limited here.

[0089] The number of segment nodes can be multiple, and multiple segment nodes can send detection signals to the mobile node. The detection signal is used to obtain the preset indicator information of the mobile node. After the mobile node receives the detection signals sent by the multiple segment nodes, it can respond to the detection signals and feedback the preset indicator information to the multiple segment nodes. After the multiple segment nodes receive the preset indicator information of the mobile node, they can record the preset indicator information of each mobile node.

[0090] Step 102: Determine the spatial coordinates of the mobile node mapped to the multi-dimensional virtual space according to the preset indicator information of the mobile node.

[0091] In an embodiment of the present invention, the segmented node can define a multi-dimensional virtual space, in which each dimension corresponds to a preset indicator, and then the preset indicator information of the mobile node is mapped to each dimension of the multi-dimensional virtual space, so as to determine the specific position of the mobile node in the space; the position of the mobile node in the multi-dimensional virtual space can intuitively represent its current network status and performance. Network administrators or automation systems can use these spatial coordinates to optimize the network, such as improving the network topology by adjusting the position of the node, or predicting and avoiding network congestion by analyzing the distribution of nodes in space.

[0092] In one embodiment of the present invention, the spatial coordinates of the mobile node mapped to the multidimensional virtual space are determined based on the preset indicator information of the mobile node, including: mapping at least one of the physical distance, moving frequency, number of hops, delay information, and energy consumption value to a dimension of the multidimensional virtual space; determining the coordinate value of the mobile node mapped to the corresponding dimension in the multidimensional virtual space based on at least one of the physical distance, moving frequency, number of hops, delay information, and energy consumption value, to obtain the spatial coordinates of the mobile node mapped to the multidimensional virtual space.

[0093] In an embodiment of the present invention, when determining the spatial coordinates of a mobile node in a multidimensional virtual space, at least one of the physical distance, moving frequency, number of hops, delay information, and energy consumption value can be first mapped to a dimension of the multidimensional virtual space, thereby forming multiple dimensions. Taking the physical distance, moving frequency, number of hops, delay information, and energy consumption value as an example, the physical distance, moving frequency, number of hops, delay information, and energy consumption value can be mapped to five dimensions of the multidimensional virtual space, and then the coordinate values ​​of the mobile node mapped to the corresponding dimensions in the multidimensional virtual space are determined respectively to obtain the spatial coordinates of the mobile node in the multidimensional virtual space.

[0094] It should be noted that the preset indicator information may also include signal strength, which can be used to represent the spatial coordinates of the mobile node mapped to the multi-dimensional virtual space. Signal strength refers to the power level of the wireless signal transmitted or received by the mobile network node. The higher the signal strength, the higher the communication quality of the network node.

[0095] In one embodiment of the present invention, the preset indicator information includes the number of hops, delay information, physical distance, energy consumption value, and movement frequency of the mobile node moving to the segment node; based on the preset indicator information of the mobile node, the spatial coordinates of the mobile node mapped to the multidimensional virtual space are determined, including: based on the number of hops, determining the coordinate value of the mobile node mapped to the first dimension in the multidimensional virtual space; based on the delay information, determining the coordinate value of the mobile node mapped to the second dimension in the multidimensional virtual space; based on the physical distance, determining the coordinate value of the mobile node mapped to the third dimension in the multidimensional virtual space; based on the energy consumption value, determining the coordinate value of the mobile node mapped to the fourth dimension in the multidimensional virtual space; based on the movement frequency, determining the coordinate value of the mobile node mapped to the fifth dimension in the multidimensional virtual space.

[0096] In the embodiment of the present invention, the hop count refers to the number of intermediate nodes that a mobile node needs to pass through to reach a segment node. In a multi-dimensional virtual space, the hop count can be used as the first dimension. The fewer the hop count, the shorter the path.

[0097] Delay information refers to the time required for a data packet to be transmitted from a mobile node to a segment node. In a multi-dimensional virtual space, delay information can be used as a second dimension to represent the communication delay between nodes. The lower the delay, the higher the communication efficiency.

[0098] Physical distance refers to the actual geographical distance between the mobile node and the segment node. In the multi-dimensional virtual space, the physical distance can be used as the third dimension to represent the actual spatial position relationship between nodes. The closer the physical distance is, the closer the nodes are in the actual space.

[0099] Energy consumption value refers to the energy consumed by a mobile node during the communication process. In a multi-dimensional virtual space, energy consumption can be used as the fourth dimension to represent the energy efficiency of the node. The lower the energy consumption, the more economical the node's energy use.

[0100] The movement frequency refers to the number of times or speed that a mobile node moves in a unit of time. In a multi-dimensional virtual space, the movement frequency can be used as the fifth dimension to represent the mobility of the node. The higher the movement frequency, the stronger the mobility of the node.

[0101] In one embodiment of the present invention, determining the coordinate value of the mobile node mapped to the first dimension in the multidimensional virtual space according to the hop count includes: determining the hop count average and hop count standard deviation of the hop count of the mobile node moving to the segment node; determining the coordinate value of the mobile node mapped to the first dimension in the multidimensional space according to the hop count, the hop count average and the hop count standard deviation;

After calculating the average hop count and the standard deviation of the hop count, the coordinate values ​​of the first dimension of the multidimensional virtual space where the mobile node m is mapped to the segment nodes a, b, and c can be calculated using formula (1), thereby obtaining z 1a 、z 1b 、z 1c , formula (1) is:

[0103]

[0104] Here, z1 refers to the coordinate value of the first dimension, and x represents the number of hops from the mobile node to the segment node.

[0107]

[0108] Among them, z2 refers to the coordinate value of the second dimension, and ti represents the delay from the mobile node to the segment node.

After calculating the average value and standard deviation of the physical distance, the coordinate value of the third dimension of the multidimensional virtual space of the mobile node m mapped to the segment nodes a, b, and c can be calculated by formula (3), thereby obtaining z 3a 、z 3b 、z 3c , formula (3) is:

The average energy consumption of the energy consumption of the mobile node moving to the segment node can be calculated as Calculate the standard deviation of energy consumption Where ei is the energy consumption of the mobile node to the i-th segment node. After calculating the average energy consumption and the standard deviation of energy consumption, the coordinate values ​​of the fourth dimension of the multidimensional virtual space where the mobile node m is mapped to the segment nodes a, b, and c can be calculated by formula (4), thereby obtaining z 4a 、z 4b 、z 4c , formula (4) is:

[0115]

[0116] Among them, z4 refers to the coordinate value of the fourth dimension, and ei represents the energy consumption of moving the node to the segment node.

[0121] Step 103 , dividing the segmented network to which the mobile node belongs according to the spatial coordinates mapped to the multi-dimensional virtual space by the mobile node.

[0122] In an embodiment of the present invention, after determining the spatial coordinates of the mobile node mapped to the multidimensional virtual space, the mobile node can be divided into corresponding segmented networks according to the spatial coordinates of the mobile node and the segmentation strategy. For example, mobile nodes with similar hop counts and delays may be divided into the same segmented network to optimize the data transmission path. The specific segmentation strategy to be adopted is not limited here.

[0123] In one embodiment of the present invention, the segmented network to which the mobile node belongs is divided according to the spatial coordinates mapped from the mobile node to the multidimensional virtual space, including: obtaining the spatial coordinates mapped from the current segmented node to the multidimensional virtual space; determining the virtual distance between the mobile node and the current segmented node according to the spatial coordinates mapped from the current segmented node to the multidimensional virtual space and the spatial coordinates mapped from the mobile node to the multidimensional virtual space; forwarding the virtual distance between the mobile node and the current segmented node to other segmented nodes; receiving the virtual distance between other segmented nodes and the mobile node forwarded by other nodes; and if the virtual distance between the current segmented node and the mobile node is less than the virtual distance between other segmented nodes and the mobile node, assigning the mobile node to the segmented network to which the current segmented node belongs.

[0127] In an embodiment of the present invention, the network topology table is a data structure that records all nodes in the network and their connection relationships. The segmented node can obtain the identification information of the mobile node, which may include the unique identification code of the mobile node (such as MAC address, IP address or other network identifier). When it is determined that the distance between the current node a and the mobile node d is the smallest, the collected identification information of the mobile node d can be added to the network topology table of the segmented network maintained by it. The segmented node a can broadcast or notify the update of the network topology table to other nodes in the segmented network to ensure that all nodes have the latest network topology information.

[0128] The present invention discloses a method for network node attribution in a segmented network, which obtains preset indicator information of a mobile node; determines the spatial coordinates of the mobile node mapped to a multidimensional virtual space according to the preset indicator information of the mobile node; and divides the segmented network to which the mobile node belongs according to the spatial coordinates of the mobile node mapped to the multidimensional virtual space. By dividing the segmented network to which the mobile node belongs in the multidimensional virtual space, the present invention can more effectively manage and optimize network resources, reduce network congestion, and improve data transmission efficiency and overall network performance. The present invention can divide the segmented network to which the mobile node belongs in real time, thereby ensuring efficient communication paths and network stability.

[0132] Step 202: Update the configuration routing table of the mobile node according to the segment network corresponding to the segment node to which the mobile node belongs.
