Description
Technical Field
The embodiment of the application relates to the technical field of internet of things, in particular to a wireless network terminal node low-power-consumption processing method, device, equipment and storage medium.
Background
The low power consumption is one of the most important characteristics of the narrow-band technology of the internet of things. The goal of the low power consumption standard is to extend the terminal battery life without affecting the coverage. Typically, low power consumption standards are used to connect devices (e.g., sensors) to a network (IoT) to share sensor data, and the data rate required for this process is orders of magnitude lower than what is normally required. Essentially, low power consumption standards utilize a sacrifice in data rate to extend battery life. In the application of the wireless internet of things, the interactive quantity of data is very small compared with the internet, and the interactive time interval is very long. It is generally desirable to have nodes that are as dormant as possible to minimize power consumption, but it is desirable for the nodes to transceive random wireless data as timely as possible. Through the air awakening technology, even if the node is in dormancy, the node can be awakened directly through a wireless means when the node is required to work.
In the prior art, a protocol mode based on scheduling can be adopted, namely, a wireless internet of things system divides continuous time into discrete time intervals, different nodes are allocated in different discrete time intervals, the nodes wake up and turn on a radio frequency receiving state in the respectively allocated time intervals, and different nodes turn on radio frequency in different time intervals, so that idle interception is effectively reduced, and energy consumption is saved. However, scheduling-based protocols require synchronization of the nodes with the gateway or base station without scalability, and scheduling maintenance and idle listening in the contention interval also cause additional overhead. A protocol approach based on detection may also be used, i.e. the gateway node sends a preamble before sending data to inform the terminal node that it is ready to receive, in order to reduce the overhead of synchronization. Typically, based on the detected LPL protocol, LPL wakes up the receiving node by sending a preamble, but because the length of the preamble is fixed and there is no destination terminal node address, it is possible for terminal neighbor nodes around the same network node to receive the preamble carrier of the source node and receive the preamble data for parsing, which causes the crosstalk problem of the nodes receiving and processing irrelevant data.

Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad invention. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Fig. 1 is a flowchart of a low power consumption processing method for a wireless network terminal node according to an embodiment of the present invention, where the embodiment is applicable to a wireless network communication system, such as communication of a narrowband internet of things, and the method may be executed by a device with computing processing capability, such as a base station and a gateway, and specifically includes the following steps:
step S101, determining a monitoring window period corresponding to each terminal node, and configuring the monitoring window period to each corresponding terminal node.
Taking communication of the internet of things as an example, a plurality of terminal nodes exist in a networking system, each terminal node executes a corresponding function, and the terminal nodes are connected to a base station or a gateway. In a wireless access scene, when a terminal node is in an idle state, the terminal node periodically wakes up to monitor the air information. In the system design process, each terminal node uses a fixed sleep-wakeup period T, and the sleep-wakeup period T is configured for each terminal node by the system. The terminal node wakes up itself to monitor whether data is sent to itself or not within a short time (node monitoring time tl) in a sleep wake-up period T, and after the node monitoring time, the terminal node enters a sleep state.
In an embodiment, a listening window period corresponding to each terminal node is determined, specifically, the sleep wakeup period T is divided into a plurality of listening windows tw, optionally, an average division mode may be adopted, that is, the number n of the listening windows is T/tw, and the listening windows tw are less than the sleep wakeup period T and greater than the node listening time tl. As shown in fig. 2, fig. 2 is a schematic diagram of dividing a sleep wakeup period T to obtain a plurality of listening windows according to an embodiment of the present invention, where in each listening window period tw, a terminal node wakes up for listening at a node listening time tl to receive data. And after the monitoring window period of each terminal node is determined, correspondingly sending the determined monitoring window period to the terminal node for configuration. Optionally, the time window of the self-wakeup of the terminal node under the gateway or the base station may be discretized in a manner that the preamble sent to the terminal node by the base station or the gateway carries the time or the time window index, thereby avoiding the crosstalk problem between the terminal nodes in a networking scenario with a proper amount of terminal nodes. For example, taking fig. 2 as an example, the first listening window tw may correspond to terminal node 1, the second listening window tw may correspond to terminal node 2, and so on. Of course, in the case of a small number of nodes, some listening windows may not correspond to the terminal nodes, and are not limited herein.
And S102, sending data to a terminal node, wherein the terminal node wakes up in a corresponding monitoring window period to receive the data.
In an embodiment, a base station or a gateway sends data to a designated terminal node in a monitoring window corresponding to the terminal node, and the terminal node wakes up in a monitoring window period corresponding to the terminal node to receive the data.
And step S103, when the change of the number of the terminal nodes is detected, dynamically adjusting the sleep wakeup period or the monitoring window period of the terminal nodes.
The number of terminal nodes in the network group may be increased or decreased, and when the number of terminal nodes is detected to be changed, the sleep wakeup period or the monitoring window period of the terminal nodes is dynamically adjusted. In one embodiment, the sleep-wake-up period of the terminal node is dynamically adjusted when a change in the number of terminal nodes is detected. Optionally, when it is determined that the number of the terminal nodes is reduced, the sleep wakeup period is shortened; and when the number of the terminal nodes is determined to be increased, prolonging the sleep-wakeup period. By dynamically adjusting the sleep wakeup period, the overall power consumption of the system is reduced to the greatest extent on the premise of ensuring the functions of the terminal nodes. The specific values of shortening and prolonging the sleep wakeup period are not limited, but the longest sleep wakeup period does not exceed the longest response time Tr of the terminal node in the networking scene. Namely, judging whether the prolonged sleep awakening period is larger than a preset response period or not; and if so, determining the preset response period as a sleep-wakeup period.
According to the scheme, the monitoring window period corresponding to each terminal node is determined, the monitoring window period corresponding to each terminal node is configured at each corresponding terminal node, data are sent to the terminal nodes, the terminal nodes are awakened in the monitoring window period corresponding to the terminal nodes to receive the data, and when the number of the terminal nodes is detected to be changed, the sleep awakening period or the monitoring window period of the terminal nodes is dynamically adjusted, so that the power consumption of the terminal nodes is effectively reduced, good flexibility is achieved, the system overhead is reduced, and meanwhile the crosstalk problem of the nodes in data receiving is avoided.
On the basis of the technical scheme, when the change of the number of the terminal nodes is detected, the period of the monitoring window of the terminal nodes is dynamically adjusted, and the method comprises the following steps: and when the number of the terminal nodes is detected to be larger than the preset number, shortening the period of the monitoring window, and sequentially ensuring that more terminal nodes are accommodated, wherein the premise is that the period time of the adjusted monitoring window is longer than the node monitoring time.
Fig. 3 is a flowchart of another method for processing low power consumption of a wireless network terminal node according to an embodiment of the present invention, and a specific listening window period corresponding to each terminal node is determined. As shown in fig. 3, the technical solution is as follows:
step S201, dividing a preset sleep wakeup period into n monitoring windows, where n is a ratio of the sleep wakeup period to the node monitoring time.
Step S202, distributing corresponding monitoring window periods according to the access time, the geographic position or the response speed of each terminal node, and configuring the corresponding monitoring window periods to each corresponding terminal node.
In one embodiment, when a terminal node accesses a base station or a gateway, a corresponding monitoring window period is allocated to the accessed terminal node, and the monitoring window periods of different terminal nodes are not overlapped. Optionally, the monitoring window period may be uniformly allocated according to the response speed and the geographic position of the terminal node, for example, the response speed of each terminal node is counted, and in a sleep wake-up period, the monitoring window in the front of the monitoring window period is preferentially allocated to the terminal node with the high response speed. In one embodiment, a terminal node with a geographical position closer to the base station or the gateway is assigned a listening window with a listening window period earlier.
Step S203, sending data to a terminal node, wherein the terminal node wakes up in a corresponding monitoring window period to receive the data.
And step S204, when the change of the number of the terminal nodes is detected, dynamically adjusting the sleep wakeup period of the terminal nodes.
In an embodiment, a cycle adjustment manner is as shown in fig. 4, and fig. 4 is a schematic diagram of dynamically adjusting a sleep wake-up cycle of a terminal node according to an embodiment of the present invention. The system calculates to obtain a default optimal sleep wake-up period, the period is uniformly configured for a newly accessed terminal node, along with the continuous access of the terminal node, if the number of the terminal nodes is less than the ratio of the wake-up sleep period to the node interception time, the period adjustment is not carried out, when the number of the accessed terminal nodes is greater than the ratio of the wake-up sleep period to the node interception time, the sleep wake-up period is prolonged, the prolonged sleep wake-up period is dynamically adjusted and configured to the terminal node by sending broadcast channel information in a broadcast mode, and the terminal node updates the sleep wake-up period and then carries out sleep and wake-up control according to the updated sleep wake-up period.
According to the scheme, the sleep awakening mechanism of the terminal nodes in the network is further optimized by dynamically adjusting the sleep awakening period of the terminal nodes, the overall power consumption is reduced, and the data communication efficiency is improved.
Fig. 5 is a flowchart of another low power consumption processing method for a wireless network terminal node according to an embodiment of the present invention, and provides a scheme for further optimizing a sleep and wake mechanism of the terminal node. As shown in fig. 5, the technical solution is as follows:
step S301, determining a monitoring window period corresponding to each terminal node, and configuring the monitoring window period to each corresponding terminal node.
Step S302, data is sent to a terminal node, and the terminal node wakes up in a corresponding monitoring window period to receive the data.
Step S303, when detecting that the number of the terminal nodes changes, dynamically adjusting the sleep wakeup period or the monitoring window period of the terminal nodes.
Step S304, sending lead code information containing the terminal node address to the terminal node, so that the terminal node enters a sleep state when determining that the terminal node is not a data receiving node.
In one embodiment, the destination address of the terminal node is added into the preamble information, so that in the internet of things networking scene of massive nodes, whether data is sent to the terminal node through the destination address as early as possible among the terminal nodes in the same time window is detected, and after a data packet which is not sent to the terminal node is detected through a destination, the terminal node goes to sleep as soon as possible, so that the power consumption caused by crosstalk is reduced to the maximum extent. In the internet of things wireless communication system, a section of preamble (generally, a plurality of binary bits (01010 … …) alternately generated by 0 and 1) is used before a data payload in the data sending and receiving processes among nodes, and the preamble is mainly used for recovering and synchronizing a clock of a wireless receiver, and information carried by the preamble is utilized to the maximum extent in a low power consumption design to awaken a terminal node in the internet of things system.
