Description

Technical Field

[0001] The present invention relates to the field of wireless Mesh network intelligent control, and in particular to a method and system for improving the performance of a wireless Mesh network. Background Art

[0002] With the continuous development of smart home technology, wireless mesh network, as an emerging communication technology, has gradually been widely used in the field of smart home. The main features of wireless mesh network are its multi-hop routing and self-organizing network capabilities, which can achieve efficient communication between multiple devices. Compared with traditional wireless communication methods, mesh network has better coverage and higher reliability, so it is adopted by more and more smart home manufacturers to achieve centralized management and control of smart devices.

[0003] Most of the smart home products on the market, such as smart lighting control, smart door locks, and thermostats, use wireless Mesh network technology. These products usually use mobile phone applications to control single devices, groups of devices, or scenes in the Mesh network. In addition, the status information of smart home devices can also be reported to the control center in real time through the Mesh network, allowing users to understand the operation of the devices at any time. This real-time and convenience greatly improves the user experience.

[0004] However, with the development of the smart home market, users' demands for the system are gradually increasing, especially in large-scale smart home systems, where the number of devices in the Mesh network is increasing. At this time, traditional wireless Mesh network technology faces a series of challenges, especially network congestion. When the number of devices in the network reaches a certain scale, the frequent status reporting of each device can easily cause network congestion, which in turn causes a series of problems, such as command transmission packet loss, increased control delay, communication anomalies, etc. These problems seriously affect the user experience.

[0005] At present, most smart home manufacturers rely on SDKs provided by wireless chip manufacturers for secondary development when developing Mesh network products. Although these SDKs provide basic device control and status reporting functions, they have not been deeply optimized to deal with network congestion. When multiple devices report their status at the same time, a large number of status report packets will appear in the network. These packets are sent to the network at the same time, which can easily cause data packet loss, thereby affecting the stability and reliability of the system.

[0006] In addition, in existing wireless mesh network control systems, all instructions are usually processed with the same priority, regardless of whether it is in normal conditions or in network congestion. This single priority processing method may result in important control instructions not being sent in time when the network is congested, further affecting the system's response speed and user experience.

[0007] In general, the existing wireless Mesh network control system performs poorly when there are a large number of devices and network congestion, and cannot meet the needs of large-scale smart home systems. In order to improve this problem, it is necessary to propose a new method to improve the performance of the wireless Mesh network system, solve the network congestion problem, and ensure the stability of the system and the real-time control. Summary of the invention

[0008] In view of this, in order to solve the problem that the existing wireless Mesh network system performs poorly when there are a large number of devices and the network is congested, the present invention proposes a method and system for improving the performance of the wireless Mesh network. Through the comprehensive application of the device-side status reporting mechanism, the air packet congestion detection and processing algorithm, and the instruction priority mechanism, the network congestion problem is effectively alleviated, the stability of the system and the real-time control are guaranteed, and the user experience is improved.

[0009] The present invention is implemented by the following technical solutions: In a first aspect, the present invention provides a method for improving the performance of a wireless mesh network, the method comprising the following steps: Establish a device status reporting mechanism. When the device status changes, set a random delay time and report the device status after the random delay. Congestion detection is performed based on the reported results of device status. The number of data packets received in the Mesh network is monitored in real time. The number of data packets received per second is counted and compared with the set threshold to determine whether the network is congested. Congestion handling is performed based on the congestion results. When network congestion is detected, the reporting of device status is further delayed, and the additional delay time is dynamically adjusted according to the actual network conditions to alleviate network congestion.

[0010] As a further solution of the present invention, a random delay time T1 is set. After the status of the device is changed, the status is reported after a random delay time T1. The range of the random delay time T1 is limited to 3 seconds.

[0011] As a further solution of the present invention, when performing congestion detection based on the reporting results of the device status, the device side collects the number of data packets received by the mesh network in real time and compares it with the set threshold R1. If the network is judged to be congested, the device status itself is sent after a random delay time T2 based on the original random delay time T1.

[0012] As a further solution of the present invention, the delay time for sending the status of its own device is the sum of T1 and T2, the time range of T1 is 0 to 3 seconds, and the range value of T2 is adjusted according to the congestion level of the mesh network air packets.

[0013] As a further solution of the present invention, when judging whether the network is congested, if the number of data packets received per second is less than the set threshold R1, the network is judged to be not congested, and the random time T2 is equal to 0 seconds; if the number of data packets received per second is greater than or equal to the set threshold R1 and less than 2 times the threshold R1, the random time T2 is generated for 1 to 2 seconds.

[0014] As a further solution of the present invention, if the number of data packets received per second is greater than or equal to 2 times the threshold R1 and less than 3 times the threshold R1, the generation time of the random time T2 is 1 to 3 seconds; similarly, if the number of data packets received per second is greater than or equal to n*R1 and less than (n+1)*R1, the random generation range of T2 is 1 to (n+1) seconds.

[0015] As a further solution of the present invention, the method for improving the performance of a wireless mesh network also includes an instruction priority mechanism. If the network is judged to be congested, the control instruction is set and sent according to the priority.

[0016] In a second aspect, the present invention also includes a system for improving the performance of a wireless mesh network, the system comprising: Device side: used to implement the device side status reporting mechanism, set the random delay time T1 for status reporting, and monitor the data packet reception in the network; Network management module: used to perform congestion detection and congestion handling, monitor network status in real time, and adjust the reporting time of device status and data transmission priority when the network is congested.

[0017] As a further solution of the present invention, the network management module includes a data packet monitoring unit and a priority adjustment unit. The data packet monitoring unit is used to detect the reception status of the data packet, and the priority adjustment unit is used to adjust the transmission priority of the data packet when network congestion is detected.

[0018] As a further solution of the present invention, the device end is provided with a random delay generator for generating a random delay time T1, and when the device state changes, the random delay time T1 is used to report the state.

[0019] As a further solution of the present invention, the network management module is also used to dynamically adjust the reporting delay of the device status according to the real-time network status, and the dynamic adjustment includes setting an additional delay T2 to cope with network congestion.

[0020] The present invention also includes a computer device, comprising: at least one processor, and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor executes the method for improving the performance of a wireless mesh network.

[0021] The present invention also includes a computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions, and the computer instructions are used to enable the computer to execute the method for improving the performance of a wireless mesh network.

[0022] Compared with the prior art, the method and system for improving the performance of a wireless Mesh network provided by the present invention significantly improves the performance and reliability of a wireless Mesh control system by introducing a random delay mechanism, real-time network congestion detection and a dynamic processing method, and has the following beneficial effects: 1. Reduced network congestion: The present invention introduces a random delay time T1 when reporting the device status, which effectively disperses the time points of device status reporting and avoids network congestion caused by multiple devices reporting their status at the same time.

[0023] 2.

When network congestion is detected, the reporting of the device status is further delayed, and the dynamically adjusted delay T2 is used to effectively relieve network pressure and ensure smooth data transmission.

[0024] 3. Improved data transmission reliability: The present invention combines the packet loss rate to judge congestion, which can more comprehensively grasp the network status and prevent network performance degradation caused by packet loss. By adjusting the data transmission priority, it ensures that key data packets are transmitted first in the case of network congestion, further improving the reliability and stability of the system.

[0025] 4. Enhanced adaptability and flexibility of the system: The device end and the network management module in the wireless mesh control system of the present invention work together to dynamically adjust the delay of device status reporting and data transmission priority according to the real-time network status, making the system more adaptable and flexible. The device end is equipped with a random delay generator and a status reporting mechanism, which can flexibly adjust the status reporting time according to actual needs, thereby adapting to different network conditions and application scenarios.

[0026] 5. Optimized user experience: The present invention reduces network delays and data transmission interruptions through effective network congestion detection and processing methods, and improves the user experience when using the wireless Mesh control system.

It has significant practical value and innovation.

[0028] These and other aspects of the present invention will be more clearly understood in the following description of the embodiments.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] In some of the processes described in the specification and claims of the present invention and the above-mentioned figures, multiple operations that appear in a specific order are included, but it should be clearly understood that these operations may not be executed in the order in which they appear in this article or executed in parallel.

It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit the "first" and "second" to be different types.

[0033] The following will be combined with the drawings in the exemplary embodiments of the present invention to clearly and completely describe the technical solutions in the exemplary embodiments of the present invention. Obviously, the exemplary embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] The technical solution of the present invention is further described below in conjunction with specific embodiments: See also Figure 1 and Figure 2 As shown, a method for improving wireless mesh network performance provided in one embodiment of the present invention includes the following steps: Establish a device status reporting mechanism. When the device status changes, set a random delay time and report the device status after the random delay. Congestion detection is performed based on the reported results of device status. The number of data packets received in the Mesh network is monitored in real time. The number of data packets received per second is counted and compared with the set threshold to determine whether the network is congested. Congestion handling is performed based on the congestion results. When network congestion is detected, the reporting of device status is further delayed, and the additional delay time is dynamically adjusted according to the actual network conditions to alleviate network congestion.

[0035] Among them, in the device-side status reporting mechanism, a random delay time T1 is set. After the device-side status changes, the status is reported after a random delay time T1, and the range of the random delay time T1 is limited to 3 seconds. In this embodiment, after the device-side status changes, the status is reported after a random delay time T1, and the range of the random time is limited to 3 seconds. If each device randomly delays a certain time T1 to report, it can avoid the congestion problem caused by multiple devices reporting the status at the same time when controlling multiple devices at the same time.

[0036] In this embodiment, when congestion detection is performed based on the reporting results of the device status, the device side collects the number of data packets received by the mesh network in real time and compares it with the set threshold R1. If the network is judged to be congested, the device status itself is sent after a random delay time T2 based on the original random delay time T1.

[0037] Among them, the delay time for sending its own device status is the sum of T1 and T2, the time range of T1 is 0 to 3 seconds, and the range value of T2 is adjusted according to the congestion level of the mesh network air packet; when judging whether the network is congested, if the number of data packets received per second is less than the set threshold R1, the network is judged to be not congested, and the random time T2 is equal to 0 seconds; if the number of data packets received per second is greater than or equal to the set threshold R1 and less than 2 times the threshold R1, the generation time of the random time T2 is 1 to 2 seconds; if the number of data packets received per second is greater than or equal to 2 times the threshold R1 and less than 3 times the threshold R1, the generation time of the random time T2 is 1 to 3 seconds; and so on, if the number of data packets received per second is greater than or equal to n*R1 and less than (n+1)*R1, the random generation range of T2 is 1 to (n+1) seconds.

[0038] In the device-side wireless mesh air packet congestion detection and processing of this embodiment, the device-side collects the number of packets received by the mesh network in real time. If it is detected that the mesh network air packet is congested, it will delay a random time T2 on the basis of the original random time T1 before sending its own device status, that is, the delay time for sending its own device status is T1+T2, the time range of T1 is 0 to 3 seconds, and the range value of T2 depends on the congestion degree of the mesh network air packet. The number of packets received within a certain time of 1s is set as PacketCount. If PacketCount is less than R1, it means that the network is not congested at this time, and T2 is equal to 0 seconds. If PacketCount is greater than or equal to R1 and less than 2*R1, T2 is randomly generated in the range of 1 to 2 seconds; if PacketCount is greater than or equal to 2*R1 and less than 3*R1, T2 is randomly generated in the range of 1 to 3 seconds; if PacketCount is greater than or equal to 3*R1 and less than 4*R1, T2 is randomly generated in the range of 1 to 4 seconds; and so on, if PacketCount is greater than or equal to n*R1 and less than (n+1)*R1, T2 is randomly generated in the range of 1 to (n+1) seconds. If the network becomes more congested during the delay waiting process, the delay time needs to be updated. The purpose of this method is to delay sending its own device status if network air packet congestion is detected at the same time. If each device can automatically detect the degree of congestion and delay sending for a certain random time, then mesh network congestion can be greatly reduced. The value of R1 can be configured and set according to the actual project congestion level.

[0039] In this embodiment, the method for improving the performance of the wireless Mesh network also includes an instruction priority mechanism. If the network is judged to be congested, the control instruction is set and sent according to the priority. Some instructions in the Mesh network can be sent with a delay, and some instructions need to be sent immediately. Therefore, the priority of different instructions is set. For example, in the case of network congestion, the control instruction has a high priority level and is sent first. The device status reporting instruction has a low priority and is sent later. Setting the priority of each instruction can optimize network resource configuration, improve system control delay, and improve user experience in congested conditions.

[0040] The present invention proposes a method for improving the performance of a wireless Mesh network. The devices in the network can automatically detect the degree of network congestion and take corresponding countermeasures, and can automatically reduce network congestion. A plurality of congestion levels are set. Even when there are a large number of network devices, the network congestion can be automatically and quickly reduced, and the system has strong robustness. While solving the network congestion from the application layer, it can ensure that there is no packet loss under congestion conditions, and can ensure that there is no control delay under congestion conditions, which greatly enhances the system performance, improves the system control delay, and improves the user experience effect. It can allow users to increase the number of devices in the same network and solve the problem of large system application congestion.

[0041] It should be understood that, although described in a certain order, these steps are not necessarily performed in sequence in the above order. Unless there is clear explanation in this article, the execution of these steps does not have strict order restriction, and these steps can be performed in other orders. Moreover, a part of the steps of the present embodiment may include a plurality of steps or a plurality of stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these steps or stages is not necessarily performed in sequence, but can be performed in turn or alternately with at least a part of the steps or stages in other steps or other steps.

[0042] In one embodiment, the present invention provides a system for improving the performance of a wireless mesh network, which is used to execute the above-mentioned method for improving the performance of a wireless mesh network. The system includes: Device side: used to implement the device side status reporting mechanism, set the random delay time T1 for status reporting, and monitor the data packet reception in the network; Network management module: used to perform congestion detection and congestion handling, monitor network status in real time, and adjust the reporting time of device status and data transmission priority when the network is congested.

[0043] The network management module includes a data packet monitoring unit and a priority adjustment unit. The data packet monitoring unit is used to detect the reception status of the data packet, and the priority adjustment unit is used to adjust the transmission priority of the data packet when network congestion is detected.

[0044] The device side is provided with a random delay generator for generating a random delay time T1, and when the device status changes, the random delay time T1 is used to report the status. The network management module is also used to dynamically adjust the reporting delay of the device status according to the real-time network status, and the dynamic adjustment includes setting an additional delay T2 to cope with network congestion.

Therefore, the operation process of the system for improving the performance of a wireless mesh network is not described in detail in this embodiment.

The present invention combines the data packet loss rate to make congestion judgments, which can more comprehensively grasp the network status and prevent the network performance from being reduced due to data packet loss.
