All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," and "fourth," etc. in the description and claims of the invention and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The terminal described in the embodiment of the present invention may also generally refer to a terminal equipped with an Internet of things sensor, and may include, for example, a smart Phone (e.g., an Android Phone, an iOS Phone, a Windows Phone, etc.), a tablet computer, a palmtop computer, a notebook computer, a Mobile Internet device (MID, Mobile Internet Devices), or a wearable device, etc., or may include other Devices with a networking function, such as a smart television, a smart air conditioner, a smart water bottle, a smart lamp, a smart switch, or some smart Devices of an Internet of things. The above terminals are only examples, not exhaustive, and include but are not limited to the above terminals. The sensors related in the embodiment of the invention can be temperature sensors, distance sensors, humidity sensors, cameras, pressure sensors, water level detectors and the like, so that the embodiment of the invention can be applied to application scenes of intelligent transportation, traffic police monitoring, water level monitoring, intelligent agriculture, industrial Internet of things and the like. Of course, the sensor involved in the embodiment of the present invention may be an intelligent sensor, and to a certain extent, may be equivalent to a terminal.
It should be explained that the ad hoc network is a network combining mobile communication and computer network, the information exchange of the network adopts the packet switching mechanism in the computer network, the terminal is a portable terminal that can move, and each terminal in the ad hoc network has both the functions of router and host. As a host, the terminal needs to run various user-oriented applications, such as an editor, a browser, and the like; as a router, a terminal needs to run a corresponding routing protocol, and completes forwarding of data packets and route maintenance work according to a routing policy and a routing table, so that a node is required to implement a proper routing protocol. The purpose of the ad hoc network routing protocol is fast, accurate and efficient, accurate and available routing information needs to be found in as short a time as possible, the ad hoc network routing protocol can adapt to the fast change of the network topology, the introduced extra time delay and the control information for maintaining the routing are reduced, and the overhead of the routing protocol is reduced, so that the limitations in the aspects of the computing capacity, the storage space, the power supply and the like of the mobile terminal are met. The embodiment of the invention is implemented based on the Internet of things ad hoc network, wherein the sensor can be installed on a terminal and also can be used independently.
In order to better understand the technical solution of the present invention, a network architecture to which the method for controlling data transmission based on device grouping according to the embodiment of the present invention is applied is briefly introduced below. As shown in fig. 1, fig. 1 is a diagram of the network architecture, wherein it includes: an Access Point (Access Point), a gateway and its standby gateway, and a plurality of terminals (represented by terminal a, terminal B, terminal C, and terminal D only) accessing the gateway and the standby gateway. The gateway can be used for receiving the reported data sent by the plurality of terminals. The gateway in the present network architecture may be configured to perform: when a target gateway in an ad hoc network of the internet of things fails, switching N terminals connected with the target gateway to a standby gateway of the target gateway, and indicating the standby gateway to send a maintenance request for requesting to maintain the target gateway to a network management center, wherein N is an integer greater than 1; detecting whether the target gateway is recovered to be normal or not; and when the target gateway returns to be normal, the N terminals are switched to the target gateway from the standby gateway. Of course, the network architecture described in fig. 1 is only a part of an ad hoc network of the internet of things, and the gateway can also access the internet. In particular, the internet of things ad hoc network may include a plurality of gateways, not only one gateway, but also a plurality of terminals. Further, for example, as shown in fig. 1-1, if the gateway in fig. 1 fails (where the dotted line X in fig. 1-1 indicates that the gateway fails), the standby gateway may be instructed to notify the network management center to perform maintenance or service on the gateway, and switch the terminal a and the terminal B accessed by the gateway to the standby gateway, and further, after the gateway is recovered, the terminal a and the terminal B may be continuously switched to the gateway.
Further, the way that the gateway sends the data packet to the AP (the terminal sends the data packet to the gateway, and the standby gateway sends the request to the network management center) may be sending through a wireless connection, which includes but is not limited to: wireless modes such as bluetooth, Wireless Fidelity (WIFI) and Zigbee, wherein the WIFI needs to comply with the standard of ieee802.11b.
It should be noted that the internet of things and the APs are only for wireless APs, because the internet of things has a large number of devices to access, and for APs, if wired connection is used, the number of APs to access is limited, and for homes, wired connection is used, which is not imaginable for wiring of home users, and in addition, the cost of the wired connection is very high, so that the connection between the terminal of the internet of things and the APs in the technical solution of the present invention is limited to wireless connection only.
Referring to fig. 2, a schematic flow chart of an embodiment of an automatic relay switching method according to an embodiment of the present invention is shown based on the network architecture described in fig. 1. The automatic relay switching method described in this embodiment includes the following steps:
201. when a target gateway in an ad hoc network of the internet of things fails, switching N terminals connected with the target gateway to a standby gateway of the target gateway, and indicating the standby gateway to send a maintenance request for requesting maintenance of the target gateway to a network management center, wherein N is an integer greater than 1.
In the ad hoc network of the internet of things, if a target gateway fails, N terminals connected with the target gateway can be switched to corresponding standby gateways, wherein N is an integer greater than 1, the standby gateways are indicated to send maintenance requests for requesting maintenance of the target gateway to a network management center, and the network management center can inform maintenance personnel to maintain or maintain the target gateway.
Optionally, the manner of determining the failure of the target gateway may be: and in a preset time, if data which needs to be reported by any terminal in the N terminals is not received, the target gateway is judged to have a fault, the N terminals connected with the target gateway can be switched to a standby gateway of the target gateway, and the standby gateway is indicated to send a maintenance request for requesting to maintain the target gateway to a network management center. After the network management center receives the maintenance request, the administrator can be instructed to repair the target gateway.
Optionally, there may be more than one standby gateway, and the embodiment of the present invention is described with only one standby gateway.
Optionally, the switching N terminals connected to the target gateway to the standby gateway of the target gateway may include the following steps:
selecting a plurality of gateways in a preset range with the target gateway as a center;
taking the gateway with the minimum load in the plurality of gateways as the standby gateway;
and switching the N terminals connected with the target gateway to the standby gateway.
The preset range may be set by the user or default by the system, for example, within 10 meters, within 20 meters, within 100 meters, within 1000 meters, within 100-500 meters, and so on. Specifically, the target gateway may be used as a center to obtain a plurality of gateways within a preset range, and the load of each gateway in the plurality of gateways may be obtained, so that the gateway with the smallest load is determined as a standby gateway, and therefore, the gateway with the smallest load may bear more number of terminals, so that the normal operation of the whole internet of things system may be ensured, and further, the N terminals connected to the target gateway are switched to the standby gateway.
Optionally, the following steps may be further included between step 201 and step 202:
200. and detecting whether the target gateway is recovered to be normal or not.
Alternatively, as shown in fig. 2-1, the step 200 may comprise the following steps:
221) monitoring whether reported data of the target gateway is received or not, wherein the reported data comprises state information of the target gateway;
222) when the reported data of the target gateway is received, analyzing the data to obtain the state information of the target gateway;
223) and matching the state information with preset state information, and confirming that the target gateway is recovered to be normal when the state information is matched with the preset state information.
The method can monitor whether reported data of a target gateway is received, where the reported data may contain state information, and the state information may include multiple indexes, and the indexes may include but are not limited to: reporting speed, stability, offline condition, load change condition and the like. The reporting rate is a rate at which the target gateway sends data to the AP, the stability is a working stability of the target gateway, the disconnection condition may be a disconnection condition of the target gateway within a preset time, and the load change condition is a load change of the target gateway. The reported data can comprise a header file and an IP address, so that the reported data can be analyzed to obtain the state information of the target gateway, the state information is matched with the preset state information, if the matching is successful, the target gateway is restored to be normal, and the preset state information can be at least one of the reporting rate, the stability, the disconnection condition and the load change condition.
Optionally, the preset state information is state information of the target gateway under a normal working condition, and if the received state information is not matched with the preset state information of the target gateway, it indicates that the target gateway is not recovered to be normal, the standby gateway may be instructed again to send a maintenance request of the target gateway to the network management center, so as to maintain the target gateway.
202. And when the target gateway returns to be normal, the N terminals are switched to the target gateway from the standby gateway.
When the target gateway returns to normal, the N terminals can be switched back from the standby gateway, so that the load of the standby gateway can be reduced.
Alternatively, as shown in fig. 2-2, the step 202 may comprise the following steps:
231) acquiring a load value of the standby gateway;
232) when the load value is smaller than a preset load value, acquiring the average transmission rate of the reported data sent by each terminal of the N terminals to the standby gateway;
233) and switching the N terminals from the standby gateway to the target gateway according to the sequence of the average transmission rate from small to large.
The preset load value can be set by default of the system or by the user. Of course, when the load of the standby gateway is small, the switching is performed, so that the data loss rate can be reduced. The AP may obtain a load value of the standby gateway, and when the load value is smaller than a preset load value, obtain an average transmission rate at which each of the N terminals sends reported data to the standby gateway, where the average transmission rate may be an average of transmission rates in a certain period of time. And switching the N terminals to the target gateway according to the sequence of the average transmission rate from small to large.
Optionally, the step 202 may include the following steps:
234) selecting M terminals in the N terminals, wherein M is a positive integer smaller than N;
235) preferentially switching the M terminals to the target gateway;
236) detecting whether the reported data of the M terminals received by the target gateway is normal or not;
237) and when the target gateway receives the reported data of the M terminals, switching other terminals except the M terminals in the N terminals to the target gateway.
The AP can select part of the terminals from the N terminals as test terminals, and supposing M terminals, the M terminals are used for detecting whether a target gateway is really recovered to be normal or not, so that the M terminals can be firstly preferentially switched to the target gateway, whether the target gateway is really recovered to be normal or not is judged by detecting whether the reported data of the M terminals are received by the target gateway or not, and when the target gateway receives the reported data of the M terminals, other terminals in the N terminals are all switched to the target gateway.
Optionally, the selecting M terminals from the N terminals includes:
acquiring the reported data volume sent by each terminal in the N terminals to the standby gateway;
dividing the N terminals into the M groups according to the reported data volume;
and selecting M terminals in the N terminals according to the weight in each group in the M groups.
The method comprises the steps of obtaining reported data volume sent by each terminal of N terminals to a standby gateway, obtaining N reported data volumes, dividing the N terminals into M groups according to the sequence of the reported data volumes from large to small, namely selecting the terminals from each group according to the number proportion (weight) of the terminals occupied by each group, and obtaining the M terminals. For example, the sequence of the N reported data amounts from large to small is as follows: A. b, C, D, E, F, G, H and I, M is 3, then, in this order from large to small, we can divide into: 3 groups, respectively: the first group (A, B and C), the second group (D, E and F), and the third group (G, H and I), one terminal from each group can be selected, thereby, obtaining 3 terminals.
It can be seen that, according to the embodiment of the present invention, when a target gateway in an ad hoc network of the internet of things fails, N terminals connected to the target gateway are switched to a standby gateway of the target gateway, and the standby gateway is instructed to send a maintenance request for requesting maintenance of the target gateway to a network management center, where N is an integer greater than 1; detecting whether the target gateway is recovered to be normal or not; and when the target gateway returns to be normal, the N terminals are switched to the target gateway from the standby gateway. Therefore, when one gateway is interrupted, the standby gateway is automatically switched, and after the one gateway is recovered, the standby gateway can be switched to the one gateway again, so that the normal transmission of data is ensured.
