[0033] See also Figure 2 , an embodiment of the present invention provides a network communication method for low-altitude areas, which may include the following steps:

[0034] S201, for a pre-built dynamic adaptive low-altitude communication network, calculating an adaptive transmission capability index of each low-altitude signal transmission node included in the network;

[0035] In the first step of the present invention, for a pre-built dynamic adaptive low-altitude communication network, the adaptive transmission capability index (ATCI) of each low-altitude signal transmission node in the network is calculated. This process involves evaluating the actual working conditions, performance and capabilities of each node to quantify its transmission capabilities under specific conditions. This calculation method takes into account multiple factors such as the signal strength, throughput, and latency of the node, so that the adaptive capability of each node can be accurately measured.

[0036] The main significance of calculating the adaptive transmission capability index is that it provides basic data support for subsequent link quality evaluation and optimal link selection. The ATCI of each node not only reflects its performance in the current environment, but also provides a reference for dynamically optimizing the communication network. By regularly updating the ATCI of each node, the network performance can be monitored in real time and adapted to various dynamic changes, thereby ensuring the reliability and efficiency of the low-altitude communication network. This evaluation mechanism can improve the stability and security of data transmission and is suitable for a variety of low-altitude application scenarios. The dynamic adaptive low-altitude communication network is mainly composed of the following components:

[0037] Low-altitude signal transmission nodes: These nodes can be drones, balloons or other aircraft, responsible for receiving and sending data. Each node is equipped with communication modules and sensors to monitor network status and environmental conditions in real time;

[0038] Base stations and relay stations: Base stations and relay stations are located on the ground or above the ground and are responsible for centralized data processing, forwarding, and network management. Base stations can establish communication links with multiple low-altitude nodes for data transmission;

[0039] Data processing center: A centralized data processing platform responsible for data storage, analysis and processing. The center can receive data from each node in real time, perform data fusion and intelligent decision-making.

[0040] User terminals: including mobile phones, computers, tablets and other devices, allowing end users to access the low-altitude communication network and obtain the required information and services.

[0041] Specifically, a calculation formula for the adaptive transmission capability index may be:

[0042] This formula takes into account the signal strength, node throughput, transmission delay, and a small constant, aiming to provide a true and effective transmission capacity evaluation for each node. The construction of the formula reflects the comprehensive impact of various factors in the communication network on node performance, and can effectively reflect the adaptive ability of each node under different working conditions.

[0043] Among them, the is the adaptive transmission capability index of node i, which is a quantitative evaluation of the node's ability to adapt to and transmit data in the network. The higher the value, the stronger the node's transmission capability. is the signal strength of node i, which measures the signal strength received by the node and directly affects the communication quality. The higher the signal strength, the more stable the node can transmit data. is the data transmission throughput of node i, which indicates the amount of data that the node can successfully transmit per unit time. It is an important indicator for measuring the transmission capacity of the node. The higher the throughput, the stronger the processing capacity and data transmission capacity of the node. is the delay of node i, which means the time required for sending data from node i to the receiving end. The lower the delay, the faster the node's response speed and the higher the transmission efficiency. In order to prevent the first preset tiny constant from the denominator being zero, it is ensured that when the signal strength or throughput of some nodes may be zero, the formula can still calculate a reasonable adaptive transmission capability index, thereby avoiding network evaluation distortion caused by calculation errors.

[0044] S202, based on the adaptive transmission capability index, calculating a corresponding comprehensive environmental adaptability index for each low-altitude signal transmission node to evaluate the adaptability of the transmission node under different environmental conditions;

[0045] Based on the adaptive transmission capability index (ATCI), the corresponding comprehensive environmental adaptability index (CEAI) is calculated for each low-altitude signal transmission node. The core of this calculation process is to evaluate the adaptability of the transmission node under different environmental conditions by integrating multiple environmental factors and node performance indicators. Specifically, this process uses the node's ATCI and the environment-related weights and adaptability efficiency scores to comprehensively evaluate the performance of each transmission node under specific environmental conditions. First, the ATCI of each node provides a basic quantitative indicator for the node's transmission capability at a specific time and under specific conditions. Then, by introducing environmental weights and adaptability efficiency scores, a more detailed analysis of the node's performance under different environmental conditions can be performed to obtain a comprehensive adaptability indicator. This can provide a more comprehensive basis for subsequent link quality evaluation and ensure that the network maintains optimal performance in a dynamically changing low-altitude environment.

[0046] The significance of calculating the Comprehensive Environmental Adaptability Index (CEAI) is that it can effectively evaluate the adaptability of each low-altitude signal transmission node in a changing environment. This capability assessment not only helps to improve the stability and reliability of the network, but also can quickly provide appropriate communication strategy guidance when the environment changes suddenly.

[0047] Specifically, a calculation formula for a comprehensive environmental adaptation index can be:

[0048] This formula is designed to provide an indicator that comprehensively evaluates the performance of a single node in multiple environments by integrating the adaptive transmission capability index, environmental weight, and adaptive efficiency score under various environmental conditions. The average value processing in the formula makes the evaluation more balanced and helps to reduce the excessive impact of a single environmental condition on the final evaluation result.

[0049] Among them, the is the comprehensive environmental adaptability index of node i, which is a quantitative evaluation of the adaptability of the node under various environmental conditions. The higher the value, the stronger the adaptability of the node in environmental changes. The adaptive performance score of node i under the kth environmental condition is calculated by comprehensively considering the success rate, average delay, signal quality and other indicators of the node under a specific environment, providing a quantitative evaluation of the adaptability of the node. is the environmental weight of node i under the kth environmental condition, indicating the importance of a specific environmental condition to the performance of the node. This weight can reflect the impact of the node's adaptability on the overall communication performance under different environments. is the number of types of environmental conditions, for:

[0050] Among them, the is the transmission success rate of node i under the kth environmental condition, is the average transmission delay time of node i under the kth environment condition, is the transmission signal quality of node i under the kth environmental condition, , , is the corresponding weight coefficient.

[0051] S203, dynamically evaluating the link quality between all low-altitude signal transmission nodes according to the comprehensive environment adaptation index;

[0052] This process aims to comprehensively judge the strength and stability of the communication link between nodes by analyzing the environmental adaptability of each node and the actual signal transmission between nodes. The quality of the link depends not only on the adaptability of each node, but also on factors such as the signal strength and transmission delay between each other. Therefore, by comprehensively evaluating CEAI, the system can dynamically update the link quality evaluation to provide a basis for the optimization management of the network. This evaluation process can be carried out under real-time conditions, automatically adjusting the link weight and optimizing the path selection according to the changes in the node environmental adaptability and the signal transmission status, thereby ensuring the smooth transmission of information in the low-altitude communication network. At the same time, this evaluation can provide a basis for future data transmission strategies and network optimization, and lay the foundation for the efficiency and reliability of communication.

[0053] The main purpose of dynamically evaluating link quality is to ensure the efficient and stable operation of the low-altitude communication network. It is specifically manifested in the following aspects:

[0054] 1. Real-time monitoring: Dynamic evaluation of link quality can monitor the communication status between nodes in real time, discover and adjust potential problems in time, and prevent communication interruption or degradation of network performance.

[0055] 2. Optimize resource allocation: Based on the link quality information obtained through evaluation, the system can allocate network resources more reasonably, select the best communication path, and improve data transmission efficiency, thereby reducing latency and increasing throughput.

[0056] 3. Enhance network adaptability: In the face of environmental changes or emergencies (such as severe weather or network congestion), dynamic assessment can help the network quickly adapt to new conditions and ensure the continuity and stability of information.

[0057] 4. Improve service quality: Through accurate link quality assessment, it can effectively improve user experience, ensure the reliability and security of data transmission, and improve the overall service quality.

[0058] Specifically, the link priority score between all low-altitude signal transmission nodes can be calculated according to the comprehensive environmental adaptation index according to the following formula as the link quality:

[0059] The design purpose of this formula is to comprehensively consider the environmental adaptability and transmission performance between two nodes to evaluate the priority of their communication links. By combining the adaptability of the node (CEAI) with the signal strength (S_{ij}) and capacity (C_{ij}) of the link, and considering the influence of transmission delay (T_{ij}), a comprehensive indicator for evaluating link quality is formed. The weighted processing in the formula ensures that more links with strong adaptability and high transmission performance have higher scores, so that they are preferred in network optimization.

[0060] Among them, the The link priority score between node i and node j reflects the quality of the communication link between the two nodes. The higher the score, the better the link is in terms of transmission efficiency and stability, and the more suitable it is for data transmission. is the link capacity between node i and node j, indicating the amount of data that can be transmitted by the link in unit time. The higher the link capacity, the stronger its carrying capacity, thereby improving the data transmission efficiency. is the link signal strength between node i and node j, representing the signal quality between the two nodes. A stronger signal strength usually means less transmission loss and higher communication quality. is the link transmission delay between node i and node j, which refers to the time required for data to be sent from node i to be received by node j. The lower the delay, the faster the response speed of the link, which is suitable for real-time communication needs. A second preset tiny constant is used to prevent the denominator from being zero, thereby ensuring that the formula can still derive a valid priority score under certain circumstances (such as when the transmission delay is zero), thereby maintaining the reliability of the calculation.

[0061] Through the above design, the link priority score can not only reflect the transmission capacity and signal quality between nodes, but also take into account the environmental adaptability, ensuring the efficient and stable operation of the low-altitude communication network under various conditions.

[0062] S204: Determine the optimal link for network communication in the low-altitude area based on the evaluated link qualities between all low-altitude signal transmission nodes.

[0063] This step uses the previously calculated Comprehensive Environmental Adaptation Index (CEAI) and Link Priority Score (LPS) data to analyze the communication performance between different nodes. Based on the link priority score, the system can dynamically select links and give priority to node pairs with higher link quality to ensure data transmission with the lowest latency and best signal quality. In this way, the system can flexibly respond to various changes that may occur in the low-altitude environment, such as node movement, signal attenuation, or environmental interference, thereby ensuring the reliability and effectiveness of communication.

[0064] Specifically, the evaluation can be performed based on the link priority score (LPS) and the comprehensive environmental adaptability index (CEAI) of each pair of nodes. The system can set a threshold, such as setting a minimum link priority score, and only links exceeding this threshold will be considered as candidate optimal links. All node pairs are sorted using the link priority score, and a certain number of the highest scores (for example, the top 10) are selected as candidate links. This can avoid wasting computing resources and focus on the links with the greatest potential.

[0065] Among the candidate links, the system makes dynamic adjustments based on real-time monitoring data (such as node status changes, environmental changes, etc.). If the quality of a link decreases (for example, link latency increases, or signal strength decreases), the system can quickly exclude the link, select the next candidate link, and include it in the communication path when necessary. During network operation, the system continuously monitors the actual communication performance (such as data transmission success rate and latency) and feeds this data back to the link evaluation mechanism. The priority score of each link is updated based on the newly collected data to ensure that the system has adaptive capabilities and can respond to environmental changes in real time.

[0066] Through the above steps, it is possible to autonomously and efficiently select the optimal link in a complex low-altitude environment to achieve high-quality network communication.

[0067] It can be seen that, for the pre-constructed dynamic adaptive low-altitude communication network, the adaptive transmission capability index of each low-altitude signal transmission node contained in the network is calculated; based on the adaptive transmission capability index, the corresponding comprehensive environmental adaptability index is calculated for each low-altitude signal transmission node to evaluate the adaptability of the transmission node under different environmental conditions; according to the comprehensive environmental adaptability index, the link quality between all low-altitude signal transmission nodes is dynamically evaluated; according to the evaluated link quality between all low-altitude signal transmission nodes, the optimal link for network communication in the low-altitude field is determined, thereby improving the reliability and efficiency of the low-altitude communication network, adapting to the changing low-altitude environment, and providing solid technical support for various low-altitude applications.
