Description

Technical Field

[0001] The present application relates to the technical field of automatic reconnection of Internet of Things devices, and specifically, to a method, device, computer-readable storage medium and electronic device for automatic reconnection of Internet of Things devices based on an exponential tidal backoff algorithm. Background Art

[0002] An IoT platform is a software system or service used to connect, manage, and monitor IoT devices. It acts as a hub in the IoT ecosystem, providing a variety of functions and services so that users can easily manage and control IoT devices, collect and analyze data, and implement automated and intelligent applications. IoT platforms typically have the following features and functions: device connection and management, data collection and storage, data analysis and processing, remote monitoring and control, security and permission management, scalability, and customization. Device connection and management are important components of an IoT platform, allowing users to easily connect various IoT devices to the platform and monitor, control, and manage these devices.

[0003] IoT devices are often in narrow bandwidth or unstable network environments. The network is usually poor and unstable. The main reason is the limitation of network infrastructure. In some areas or places, the network infrastructure may be imperfect, resulting in limited bandwidth resources. The second is network congestion. In a busy network environment, bandwidth resources may be consumed by a large number of devices or users at the same time, resulting in network congestion and bandwidth bottlenecks. Especially during peak hours, such as daytime working hours or during specific activities, the problem of network congestion may be more prominent. The third is technical limitations. IoT devices usually use low-power, low-cost communication technologies, which may limit the bandwidth capabilities of the device. Therefore, the connection between the IoT device and the server may be unstable, triggering disconnection and reconnection, and the network environment may be unstable for a long period of time, resulting in repeated connection failures of IoT devices when disconnecting and reconnecting from the server.

[0004] In the current common technical solutions, IoT platforms generally use a fixed reconnection interval. However, in actual environments, network conditions are usually changeable. Setting a fixed reconnection interval will result in frequent reconnection failures or long waiting time for reconnection. Summary of the invention

[0032] In this embodiment, an automatic reconnection method for Internet of Things devices based on the exponential tidal backoff algorithm running on a mobile terminal, a computer terminal, or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in a different order.

[0033] Figure 2 is a flowchart of the automatic reconnection method for Internet of Things devices based on the exponential tidal backoff algorithm according to an embodiment of the present application. AsFigure 2 As shown in the figure, the method includes the following steps:

[0034] Step S201: Set the reconnect reference times of the above-mentioned Internet of Things device according to the connection requirements of the Internet of Things device, and perform disconnection detection on the above-mentioned Internet of Things device to determine whether the above-mentioned Internet of Things device is disconnected;

[0035] Specifically, set the reconnect reference times of the above-mentioned Internet of Things device according to the connection requirements of the Internet of Things device. The connection requirements of the Internet of Things device include requirements such as stable network connection, low latency, high bandwidth, security, and reliability. According to these connection requirements, the reconnect reference times of the Internet of Things device can be set to ensure that the device can reconnect in time and resume normal operation when there are problems with the network connection.

[0036] Step S202: When the above-mentioned Internet of Things device is disconnected, obtain the reconnect times of the above-mentioned Internet of Things device;

[0037] Step S203: According to the magnitude relationship between the above-mentioned reconnect times and the above-mentioned reconnect reference times, use the exponential tidal backoff algorithm to adjust the reconnect time interval of the above-mentioned Internet of Things device.

[0038] Specifically, use the backoff algorithm to adjust the automatic reconnect interval. By setting an initial waiting time and then using the backoff algorithm to control the automatic reconnect gap, the waiting time is gradually increased after each reconnect attempt to avoid a large number of reconnect attempts caused by network connection interruptions.

[0039] Through this embodiment, set the reconnect reference times of the above-mentioned Internet of Things device according to the connection requirements of the Internet of Things device, and perform disconnection detection on the Internet of Things device to determine whether the Internet of Things device is disconnected; when the Internet of Things device is disconnected, obtain the reconnect times of the Internet of Things device; according to the magnitude relationship between the reconnect times and the reconnect reference times, use the exponential tidal backoff algorithm to adjust the reconnect time interval of the Internet of Things device. Based on the reconnect strategy of the exponential tidal backoff algorithm, it can avoid a large number of reconnect attempts caused by network connection interruptions. A reasonable reconnect logic can not only improve the stability and reliability of the Internet of Things device, avoid data loss and latency problems caused by network connection interruptions, but also reduce the pressure on the server side due to frequent connections, and solve the problem that the existing reconnect solutions for Internet of Things devices are prone to frequent failed reconnects or too long waiting times for reconnects.

[0040] In the specific implementation process, according to the magnitude relationship between the above-mentioned reconnect times and the above-mentioned reconnect reference times, using the exponential tidal backoff algorithm to adjust the reconnect time interval of the above-mentioned Internet of Things device includes: according to the magnitude relationship between the above-mentioned reconnect times and the above-mentioned reconnect reference times, using the first formula: Determine the reconnection time interval of the above Internet of Things device, where t(n) is the above reconnection time interval, β is the maximum reconnection time interval, n is the above reconnection times, and N is the above reconnection reference times.

[0041] The exponential tidal backoff algorithm of this method consists of three piecewise functions. The first function uses exponential growth, which can make the automatic reconnection time increase rapidly in the initial few failed reconnections, avoiding a large number of reconnection attempts caused by connection interruptions in a short time. The second function also uses an exponential function, but it is opposite to the first one. As the number of retries increases, the exponent decreases successively. This design can not only ensure that the automatic reconnection time can still increase steadily, further reducing the computational overhead caused by connection applications between the device and the server, but also avoid the device remaining in a long offline state when the network state has recovered due to too rapid exponential growth. The third segment represents growth truncation. When the reconnection interval grows to a predetermined size, the reconnection request will be initiated by maintaining this automatic reconnection interval all the time.

[0042] Specifically, after adjusting the reconnection time interval of the above Internet of Things device by using the exponential tidal backoff algorithm, the above method further includes: obtaining multiple historical disconnection recovery times of the above Internet of Things device, and determining the average disconnection recovery time of the above Internet of Things device according to the multiple above historical disconnection recovery times, where the above historical disconnection recovery time is the time from disconnection to reconnection of the above Internet of Things device; and correcting the above exponential tidal backoff algorithm according to the average disconnection recovery time to obtain the target exponential tidal backoff algorithm.

[0043] This method corrects the original exponential tidal backoff algorithm according to the average disconnection recovery time of the Internet of Things device to obtain the target exponential tidal backoff algorithm. In this way, a fixed reconnection reference number N can be set so that the device has a high probability of being able to connect successfully when reconnecting about N / 2 times. The lower the value of N, the more the number of connection attempts of the Internet of Things platform device to the server can be reduced, and the computational overhead generated by the device and the server due to reconnection can be reduced.

[0044] More specifically, correcting the above exponential tidal backoff algorithm according to the average disconnection recovery time to obtain the target exponential tidal backoff algorithm includes: using the second formula: Determine the above target exponential tidal backoff algorithm, where t(n) is the above reconnection time interval, α is the reconnection time interval adjustment coefficient, β is the maximum reconnection time interval, is the above average disconnection recovery time, n is the above reconnection times, and N is the above reconnection reference times.

[0045] Among them, the reconnection time interval adjustment coefficient α is determined by the recorded average time from historical offline to reconnection.

[0046] Further, after correcting the exponential tidal backoff algorithm according to the above average disconnection recovery time to obtain the target exponential tidal backoff algorithm, the above method further includes: continuing to perform the above disconnection detection on the above Internet of Things device; when detecting that the above Internet of Things device is disconnected, according to the magnitude relationship between the above reconnection times and the above reconnection reference times, adjusting the above reconnection time interval of the above Internet of Things device by using the above target exponential tidal backoff algorithm.

[0047] The method uses the corrected target exponential tidal backoff algorithm, which is more suitable for the automatic reconnection interval control scenario of Internet of Things platform devices. It uses a three-segment piecewise function to adjust and control the reconnection interval, which not only solves the problem of a large number of reconnection attempts but also avoids the situation where the reconnection interval grows too large, resulting in the device still being in an offline waiting state for a long time even though the network has recovered. In addition, all devices on the Internet of Things platform are in different environments, so their network environments and states are also different. The time required for a device to disconnect and reconnect due to network problems will also be different. By adding adaptive adjustments suitable for different devices, the problem that the automatic reconnection scheme is not applicable due to network environment differences among different devices is solved.

[0048] Furthermore, after adjusting the reconnection time interval of the above Internet of Things device by using the exponential tidal backoff algorithm, the above method further includes: after a preset time period, determining whether the above Internet of Things device has reconnected successfully; when the above Internet of Things device still fails to connect successfully, generating a prompt message, where the above prompt message is used to remind relevant personnel to check the above Internet of Things device.

[0049] The method determines the maximum reconnection time of the Internet of Things device by setting a preset time period, avoiding losses caused by the Internet of Things device failing to reconnect for a long time.

[0050] Specifically, after adjusting the reconnection time interval of the above Internet of Things device by using the exponential tidal backoff algorithm, the above method further includes: when detecting that the above Internet of Things device has reconnected successfully, recording the disconnection recovery time of the above Internet of Things device.

[0051] The method records the disconnection recovery time of the Internet of Things device for subsequent adjustment of the exponential tidal backoff algorithm, solving the problem that the automatic reconnection scheme is not applicable due to network environment differences among different devices.

[0052] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the automatic reconnection method for Internet of Things devices based on the exponential tidal backoff algorithm of the present application will be described in detail below in conjunction with specific embodiments.

[0053] This embodiment relates to a specific method for automatic reconnection of Internet of Things devices based on an exponential tidal backoff algorithm, which specifically includes the following content:

[0054] Firstly, it is the adjustment of the automatic reconnection interval of Internet of Things platform devices based on the backoff algorithm. After the disconnection of Internet of Things platform devices, automatic reconnection is required. Generally, the platform devices use a fixed interval time for automatic reconnection. In this embodiment, the backoff algorithm is used to adjust the automatic reconnection interval. By setting an initial waiting time and then using the backoff algorithm to control the automatic reconnection gap, the waiting time is gradually increased after each reconnection attempt to avoid a large number of reconnection attempts caused by network connection interruptions.

[0055] Secondly, it is the optimization of the backoff algorithm in the scenario of controlling the automatic reconnection interval of Internet of Things platform devices. As Figure 3 shown, it shows the growth of the reconnection interval with the increase in the number of device reconnections using the exponential backoff algorithm, the linear backoff algorithm, and the exponential tidal backoff algorithm. The exponential tidal backoff algorithm proposed in this embodiment consists of three piecewise functions, and the algorithm is as shown in the formula: shown. The first function is the same as the exponential backoff algorithm, using exponential growth, which can make the automatic reconnection time grow rapidly in the initial few failed reconnections to avoid a large number of reconnection attempts caused by connection interruptions in a short period of time. The second function also uses an exponential function, but is opposite to the first one, and the exponent decreases successively with the increase in the number of retries. This design can not only ensure that the automatic reconnection time can still grow steadily, further reducing the computational overhead caused by connection requests between the device and the server, but also avoid the device remaining in a long offline state when the network state has recovered due to too fast exponential growth. The third segment represents growth truncation. When the reconnection interval grows to a predetermined size, the reconnection request will be initiated with this automatic reconnection interval maintained all the time.

[0056] Finally, it is the adaptive adjustment of the reconnection interval increase amplitude based on the average statistical value of the device reconnection times. As shown in the formula: shown, a constant α is added, and α is determined by the recorded average time from historical offline to connection recovery. By adjusting α, a fixed number of reconnection times N can be set so that the device has a high probability of being able to connect successfully around N / 2 reconnection times. The lower the N value, the more the number of connection attempts of the Internet of Things platform device to the server can be reduced, and the computational overhead generated by the device and the server due to reconnection can be reduced. In summary, the automatic reconnection process of Internet of Things devices based on the exponential tidal backoff algorithm is as Figure 4 shown.

[0057] In this embodiment, the automatic reconnection of IoT platform devices adopts a backoff algorithm, which can make the reconnection interval increase rapidly, avoid the device sending multiple reconnection requests to the server in a short period of time, reduce the consumption of computing resources of the device and the server, and reduce the system pressure. The proposed exponential tidal backoff algorithm is more suitable for the scenario of controlling the automatic reconnection interval of IoT platform devices. It uses a three-segment piecewise function to adjust and control the reconnection interval, which not only solves the problem of a large number of reconnection attempts, but also avoids the situation where the reconnection interval grows too large, resulting in the device still being in an offline waiting state for a long time even though the network has recovered. The environments of all devices in the IoT platform are different, so the network environments and states are also different. The time required for the device to disconnect and reconnect due to network problems will also be different. By adding adaptive adjustments suitable for different devices, the problem that the automatic reconnection scheme is not applicable due to network environment differences among different devices is solved.

[0058] This embodiment of the present application also provides an automatic reconnection device for IoT devices based on the exponential tidal backoff algorithm. It should be noted that the automatic reconnection device for IoT devices based on the exponential tidal backoff algorithm in this embodiment of the present application can be used to execute the method for automatically reconnecting IoT devices based on the exponential tidal backoff algorithm provided in this embodiment of the present application. This device is used to implement the above embodiments and preferred implementation manners, and those that have been described will not be repeated.
