Description

Technical Field

[0001] The present invention relates to the field of edge computing technology, and in particular to a reliable, energy-saving, and time-saving wireless communication status perception optimization method and system for high-mobility environments. Background Art

[0002] With the rapid development of the Internet of Things, Internet of Vehicles, Internet of Ships, Internet of Flight and other fields, edge computing technology has made continuous breakthroughs, and various interconnected services have been extended to the edge, thereby increasing the scale and complexity of information systems, and bringing challenges to the organization and application of interconnectedness in edge environments.

[0003] In today's market, edge environments host a vast array of information devices used to build various small and medium-sized information systems. However, these devices possess varying hardware and software resources, with varying performance levels, some even exceedingly poor. Furthermore, complex terrain and weather conditions during mobility can lead to limited and weak connectivity at the edge. Existing wireless communication status awareness technologies typically rely on periodic active detection to determine the connectivity status of other nodes. However, these limited and weak connectivity issues can lead to multiple retransmissions, resulting in a high bandwidth consumption of edge communication links.

[0004] Currently, there is no optimized method for wireless communication status perception under high-mobility and weak-connection communication conditions at the edge. Therefore, it has become an urgent need in the current information system construction to comprehensively design a lightweight method to perceive the wireless communication status under high-mobility conditions at the edge, support efficient availability under weak connections where physical distribution and wireless communication systems perceive each other's communication status, and reduce the risks of inefficient wireless communication status perception in distributed systems due to limited edge communication resources. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to provide a reliable, energy-saving and time-saving wireless communication status perception optimization method and system for high-mobility environments.

[0006] Technical Solution: The wireless communication status perception optimization method for high-mobility environments described in the present invention includes the following steps on any edge node:

[0007] S1. Using a wireless communication device to monitor, receive, identify, and perceive the wireless communication source, and based on the edge address book, when the wireless communication source is perceived to be another edge node, confirm and update the communication status between the local node and the corresponding edge node.

[0008] S2. Subscribe to and receive aggregated information about the normal communication status between the local node and the corresponding edge node through the communication status monitoring software, and timely detect edge nodes with unclear communication status with the local node;

[0009] S3. Using the communication status monitoring software, based on the preset wireless communication objects of interest, a detection message is sent to the wireless communication objects of interest whose communication status with the local node is unknown, and the communication status between the local node and the corresponding wireless communication objects of interest is actively sensed and summarized;

[0010] S4. The communication status monitoring software periodically checks the edge nodes whose communication status with the local node is normal or abnormal but has not been updated after the timeout, sends a detection message to the edge node, and actively senses and summarizes the communication status between the local node and the corresponding edge node.

[0011] Furthermore, the communication status includes normal, abnormal and unknown.

[0012] Furthermore, in step S1, wireless communication messages sent to the local node and sent to other edge nodes and received by the wireless communication device of the local node are monitored and received by the wireless communication device.

[0013] Furthermore, the step S1 includes:

[0014] S11. The wireless communication device monitors and receives wireless communication messages from all edge nodes;

[0015] S12, the wireless communication device identifies the source node of the received wireless communication message, i.e., the wireless communication source. If the wireless communication source cannot be identified as a node in the edge communication list, the process ends directly.

[0016] S13. When the wireless communication device senses that the wireless communication signal source is another edge node, it confirms that the communication status between the local node and the corresponding edge node is normal, and packages it into a monitoring, receiving, identifying, and communicating status update message for publication.

[0017] Furthermore, the step S2 includes:

[0018] S21. The communication status monitoring software receives and identifies the communication status update message based on the subscription monitoring, and receives that the communication status between the local node and the corresponding edge node is normal;

[0019] S22. The communication status monitoring software summarizes and updates the communication status of the corresponding edge nodes into a wireless communication status table, where the wireless communication status table includes the communication status of the local node and all edge nodes;

[0020] S23. When the communication status update check cycle is reached, the communication status monitoring software counts edge nodes whose communication status with the local node is unknown according to the wireless communication status table.

[0021] Furthermore, the wireless communication attention objects in step S3 include multiple edge nodes that are in wireless communication with the local node and that the user pays special attention to.

[0022] Furthermore, step S3 includes:

[0023] S31. The communication status monitoring software allows users to pre-set and adjust wireless communication focus objects;

[0024] S32. The communication status monitoring software obtains wireless communication objects of interest whose communication status with the local node is unknown based on the wireless communication objects of interest and the real-time statistics of edge nodes whose communication status with the local node is unknown;

[0025] S33, the communication status monitoring software sends a communication status inquiry message to each wireless communication target whose communication status with the local node is unknown;

[0026] S34. The communication status monitoring software monitors and receives a communication status response message from a wireless communication object whose communication status with the local node is unknown. If no communication status response message is received within the communication detection upper limit time, the communication status between the local node and the corresponding wireless communication object is abnormal. Otherwise, the communication status between the local node and the corresponding wireless communication object is normal.

[0027] S35. The communication status monitoring software summarizes and updates the communication status of the corresponding wireless communication focus object into the wireless communication status table.

[0028] Furthermore, the step S4 includes:

[0029] S41. The communication status monitoring software periodically checks the wireless communication status table according to the communication status update check cycle, and finds that the communication status is invalid, that is, the edge node with normal or abnormal communication status with the local node but has not been updated beyond the communication status invalid time;

[0030] S42, the communication status monitoring software sends a communication status inquiry message to each edge node whose communication status has failed;

[0031] S43. The communication status monitoring software monitors and receives a communication status response message from an edge node whose communication status has failed. If no communication status response message is received within the communication detection upper limit time, the communication status between the local node and the corresponding edge node whose communication status has failed is abnormal. Otherwise, the communication status between the local node and the corresponding edge node whose communication status has failed is normal.

[0032] S44. The communication status monitoring software summarizes and updates the communication status of the edge nodes whose corresponding communication status has expired into the wireless communication status table.

[0033] The wireless communication status perception optimization system for high-mobility environments of the present invention includes:

[0034] Wireless communication devices, deployed on edge nodes, are configured as follows:

[0035] Based on the ability to send and receive wireless communication messages for upper-layer application software, it monitors, receives, identifies, and perceives the wireless communication source. When it perceives that the wireless communication source is another edge node based on the edge address book, it confirms and updates the communication status between the local node and the corresponding edge node.

[0036] The communication status monitoring software is deployed on the edge node and is configured as follows:

[0037] Subscribe to receive and summarize the normal communication status between the local node and the corresponding edge node, and timely perceive the edge node with unknown communication status with the local node;

[0038] Based on the preset wireless communication objects of interest, the system sends detection messages to the wireless communication objects of interest whose communication status with the local node is unknown, and actively senses and summarizes the communication status between the local node and the corresponding wireless communication objects of interest;

[0039] Regularly check the edge nodes that have learned that the communication status with the local node is normal or abnormal but has not been updated after the timeout, send detection messages to the edge nodes, and actively perceive and summarize the communication status between the local node and the corresponding edge nodes.

[0040] Beneficial effects: Compared with the existing technology, the present invention has the following significant advantages: In a high-mobility, weak-connection communication environment at the edge, the present invention adds monitoring, receiving, identifying and perceiving the communication status of the signal source to the wireless communication equipment, and supplements the communication status with the communication status monitoring software to send a message to detect, perceive and update the communication status, and collaboratively optimize and improve the wireless communication status perception path, and support the perception of the communication status between distributed wireless communication systems; it not only supports the efficient perception of the communication status between distributed wireless communication systems, but also realizes the optimization of wireless communication status perception for scenarios in high-mobility environments, making it more practical for business information systems such as motor vehicles, ships, and aircraft, and supports reliable, energy-saving and time-saving perception of the communication status between distributed wireless communication systems, so as to carry out application sharing information and timely distribution based on it, which helps to improve the practicality and application efficiency of the wireless communication status perception at the edge of the system.

[0046] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, the wireless communication state perception optimization method for high-mobility environments described in the present invention includes the following steps on any edge node:

[0048] S1. Passive perception of normal communication status. By monitoring and receiving wireless communication signals through wireless communication devices, the node identifies and perceives the wireless communication signal source. When the edge address book detects that the wireless communication signal source is another edge node, the node confirms and updates the normal communication status between the local node and the corresponding edge node.

[0049] The monitoring reception means receiving wireless communication messages sent to other edge nodes and receivable through the wireless communication device of the local node in addition to receiving the wireless communication messages sent to the local node;

[0050] The communication status refers to the wireless communication status between edge nodes, including normal, abnormal and unknown.

[0051] like Figure 2 As shown, the detailed steps for passive perception of a node with normal communication status are as follows:

[0052] S11. Monitoring and receiving wireless communication messages from edge nodes. The wireless communication device monitors and receives wireless communication messages from all edge nodes.

[0053] S12, wireless communication source node identification and determination. The wireless communication device identifies the source node of the received wireless communication message, i.e., the wireless communication source. If the wireless communication source cannot be identified as a node in the edge communication list, the process ends directly.

[0054] S13, Node Update and Release of Normal Communication Status: When the wireless communication device senses that the wireless communication signal source is another edge node, it confirms that the communication status between the local node and the corresponding edge node is normal, and packages it into a monitoring, receiving, and identifying communication status update message for release.

[0055] S2. Timely detection of nodes with unclear communication status. By subscribing to and receiving aggregated information about the communication status between the local node and the corresponding edge node, the communication status monitoring software can be used to timely detect edge nodes with unclear communication status with the local node.

[0056] like Figure 3 As shown in the figure, the detailed steps for timely perception of nodes with unknown communication status are as follows:

[0057] S21. The node with normal communication status subscribes and receives. The communication status monitoring software identifies the communication status update message based on the subscription monitoring reception, and receives the communication status between the local node and the corresponding edge node as normal;

[0058] S22. Update the communication status of the nodes with normal communication status. The communication status monitoring software updates the communication status of the corresponding edge nodes into the wireless communication status table. The wireless communication status table includes the communication status of the local node and all edge nodes.

[0059] S23. Timely statistics of nodes with unclear communication status. When the communication status update check cycle is reached, the communication status monitoring software counts edge nodes with unclear communication status with the local node based on the wireless communication status table.

[0060] S3. Update of communication status attention node detection. The communication status monitoring software sends detection messages to wireless communication attention objects whose communication status with the local node is unknown based on the preset wireless communication attention objects, actively sensing and summarizing whether the communication status between the local node and the corresponding wireless communication attention objects is normal or abnormal.

[0061] The wireless communication attention objects refer to several edge nodes that are in wireless communication with the local node and that the user pays special attention to.

[0062] like Figure 4 As shown, the detailed steps for detecting and updating the communication status attention node are as follows:

[0063] S31. Pre-setting of communication status attention nodes. The communication status monitoring software supports users to pre-set and adjust wireless communication attention objects;

[0064] S32. Nodes with unknown communication status are timely informed. The communication status monitoring software obtains wireless communication objects with unknown communication status with the local node based on the wireless communication objects and the real-time statistics of edge nodes with unknown communication status with the local node;

[0065] S33, Querying the status of nodes with unknown communication status. The communication status monitoring software sends a communication status query message to each wireless communication target whose communication status with the local node is unknown;

[0066] S34. Determine the status of the node with unknown communication status. The communication status monitoring software monitors and receives the communication status response report of the wireless communication object with unknown communication status with the local node: if the communication status response report is not received within the communication detection upper limit time, the communication status of the local node and the corresponding wireless communication object is abnormal; otherwise, the communication status of the local node and the corresponding wireless communication object is normal;

[0067] S35: The edge node communication status is summarized and updated. The communication status monitoring software summarizes and updates the communication status of the corresponding wireless communication focus object into the wireless communication status table.

[0068] S4. Detect and update nodes with timeout communication status. The communication status monitoring software periodically checks edge nodes that have normal or abnormal communication status with the local node but have not updated after a timeout. Probes are sent to these edge nodes to proactively detect and summarize whether the communication status between the local node and the corresponding edge node is normal or abnormal.

[0069] like Figure 5 As shown, the detailed steps for detecting and updating the communication status timeout node are as follows:

[0070] S41, periodic check of communication status failure nodes. The communication status monitoring software regularly checks the wireless communication status table according to the communication status update check cycle, and finds out the communication status failure, that is, the edge node whose communication status with the local node is normal or abnormal but has not been updated beyond the communication status failure time;

[0071] S42, Querying the status of nodes with failed communication status. The communication status monitoring software sends a communication status query message to each edge node with failed communication status;

[0072] S43. Determine the status of the node with failed communication status. The communication status monitoring software monitors and receives the communication status response message of the edge node with failed communication status: if the communication status response message is not received within the communication detection upper limit time, the communication status between the local node and the corresponding edge node with failed communication status is abnormal; otherwise, the communication status between the local node and the corresponding edge node with failed communication status is normal;

[0073] S44, the communication status determination node summarizes and updates the communication status of the edge nodes whose corresponding communication status has expired, and adds the update to the wireless communication status table.

[0074] The wireless communication status perception optimization system for high-mobility environments of the present invention includes:

[0075] Deploy wireless communication equipment and communication status monitoring software on edge nodes.

[0076] The wireless communication device is configured to:

[0077] On the basis of having the ability to send and receive wireless communication messages for upper-layer application software, it can monitor, receive, identify and perceive the source of wireless communication. When it perceives that the source of wireless communication is other edge nodes based on the edge address book, it confirms and updates the communication status between the local node and the corresponding edge node to be normal.

[0078] The communication status monitoring software is configured to:

[0079] Subscribe to receive and summarize the normal communication status between the local node and the corresponding edge node, and timely perceive the edge node with unknown communication status with the local node;

[0080] Based on the preset wireless communication objects of interest, the system sends detection messages to the wireless communication objects of interest whose communication status with the local node is unknown, and actively senses and summarizes whether the communication status between the local node and the corresponding wireless communication objects of interest is normal or abnormal;

[0081] Regularly check the edge nodes that have learned that the communication status with the local node is normal or abnormal but has not been updated after the timeout, send detection messages to them, and actively perceive and summarize whether the communication status between the local node and the corresponding edge node is normal or abnormal.
