Embodiment 1

[0042] figure 1 It is a flowchart of a method for updating an access path of an Internet of Things node provided by Embodiment 1 of the present invention. The Internet of Things node access path update method provided in the embodiment can be executed by various operating devices (mainly Internet of Things node devices) used for updating the Internet of Things node access path, and the operating device can be implemented through software and / or hardware Realized by means, the operating device may be composed of two or more physical entities, or may be composed of one physical entity.

[0043] The specific application scenario for this solution is a large-scale wireless sensor network, especially a queuing network composed of wireless sensor networks. The current wireless sensor network generally adopts a cluster structure. Taking two clusters as an example, each cluster may have an arrival node, a transmission node, and a sink node. Aggregate communication between nodes. St...

Embodiment 2

[0063] figure 2 It is a schematic structural diagram of an apparatus for updating an access path of an Internet of Things node provided by Embodiment 2 of the present invention. refer to figure 2 , the IoT node access path update device includes: a relationship confirmation unit 210 , a node disconnection unit 220 , a node addition unit 230 , a node deletion unit 240 and a path output unit 250 .

[0064] Among them, the relationship confirmation unit 210 is used to obtain the transition probability of the IoT node, and confirm the connection relationship of the IoT node based on the transition probability; the node disconnection unit 220 is used to connect the network with a preset external reach rate The first Internet of Things node is disconnected from the currently connected second Internet of Things node; the node adding unit 230 is used to use the first Internet of Things node as a root node to add a leaf node according to the node transfer relationship; the node dele...

Embodiment 3

[0073] image 3 A schematic structural diagram of an IoT node device provided in Embodiment 3 of the present invention, as shown in image 3 As shown, the terminal device includes a processor 310, a memory 320, an input device 330, an output device 340, and a communication device 350; the number of processors 310 in the terminal device may be one or more, image 3 A processor 310 is taken as an example; the processor 310, memory 320, input device 330, output device 340, and communication device 350 in the terminal device can be connected through a bus or other methods, image 3 Take connection via bus as an example.

[0074] The memory 320, as a computer-readable storage medium, can be used to store software programs, computer-executable programs and modules, such as program instructions / modules corresponding to the method for updating the Internet of Things node access path in the embodiment of the present invention (for example, the Internet of Things The node accesses the...

Abstract

The embodiment of the invention discloses an Internet of Things node access path updating method and device, Internet of Things node equipment and a storage medium. The method comprises the steps of obtaining a transition probability of an Internet of Things node, and determining a connection relationship of the Internet of Things node based on the transition probability; disconnecting the first Internet of Things node with the preset network external arrival rate from the currently connected second Internet of Things node; taking the first Internet of Things node as a root node, and adding aleaf node according to a node transfer relationship; deleting the child node according to the node number relationship between the leaf node and the father node as well as between the leaf node and the brother node; and starting to traverse the currently reserved child nodes from the first Internet of Things node, and outputting all paths capable of reaching the second Internet of Things node. According to the scheme, when path confirmation is carried out on the queuing network, the path between the two nodes is quickly and optimally selected, so calculation tasks and calculation power requirements of the whole Internet of Things during path planning are effectively reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technology, and in particular, to a method, device, device, and storage medium for updating access paths of nodes in the Internet of Things. Background technique [0002] The Internet of Things (IoT) is regarded as a major opportunity for development and change in the information field, and is expected to bring revolutionary changes. In a more general view, this revolutionary change will be in industry, agriculture, property, City management, safety and fire protection and other fields have a full range of impact. But technically speaking, the Internet of Things not only changes the main body of data transmission, but also has obvious differences from traditional communication. For example, massive IoT is characterized by a large number of users sending very small packets sporadically, unlike traditional cellular communications. [0003] In the process of applying the large-scale...
