Problems solved by technology

However, when forwarding and transmitting specific data, the relay server sends the received data packets of the terminal nodes to the cloud server one by one in sequence, regardless of the fact that the actual link bandwidth is usually much larger than that of a single data packet. The amount of data does not consider the urgency of data packets of certain terminal nodes, and the efficiency, real-time, and fairness of data transmission cannot be taken into account

Embodiment 1

[0034] figure 1 A schematic flowchart of the method for dynamic adaptation of Internet of Things bandwidth resources provided in this embodiment. like figure 1 As shown, the method for dynamically adapting bandwidth resources of the Internet of Things includes the following steps:

[0035] (1) The relay server initializes the parameter matrix, weight vector, and time slot; buffers the data packets sent by the terminal node.

[0036] In the specific implementation process, the transit server initialization parameter matrix ( c ij )∈ R N*M and weight vector ;in, R N*M A matrix of N rows and M columns representing the real number field; for each i ∈[ 1,N ], j ∈ [ 1,M ], initial value c ij =1, All elements of takes fixed default values; c ij means the first i the first node of the terminal node j parameters, vector elements w j means the first j weight of the parameters. The parameter here can be the total number of data packets sent by each terminal nod...

Embodiment 2

[0052] This embodiment provides an Internet of Things bandwidth resource dynamic adaptation system, such as figure 2 As shown, it includes a transit server, a terminal node, and a cloud server, and the transit server, the terminal node, and the cloud server execute the method steps of the method for dynamically adapting bandwidth resources of the Internet of Things described in Embodiment 1.

Embodiment 3

[0054] This embodiment provides a storage medium, such as image 3 As shown, it includes a memory and a processor, the memory stores a program, and when the program is called and executed by the processor, the processor executes the method steps of the method for dynamically adapting bandwidth resources of the Internet of Things according to Embodiment 1 .

Abstract

The invention relates to a dynamic adaptation method for bandwidth resources of the Internet of Things. The method comprises the following steps: (1) initializing a transit server; caching a data packet sent by the terminal node; (2) starting a timer by the transit server, and sequentially taking out the data packets from the cache to form a set; (3) if a timing ending condition is reached, calculating a link peak capacity BW; (4) judging whether the sum of the elements in the set D is smaller than or equal to the link peak capacity BW; (4.1) if yes, directly sending the set D to a cloud server, and then executing the step (3); (4.2) if not, generating a temporary set and sorting the temporary set to form a set D '; (4.2. 1) subtracting q from subscripts of all the elements of D ', if the sum of all the elements of D' is not greater than BW, sending all the elements to the cloud server, otherwise, executing the step S until all the data packets are sent; and then executing the step (3).

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, and more particularly, to a method, system and storage medium for dynamic adaptation of bandwidth resources of the Internet of Things. Background technique [0002] In the field of IoT network topology design and data processing, it is often necessary to design a reasonable system architecture and data transmission and processing algorithms according to the hardware performance of the IoT terminal nodes, so as to provide early warning of the monitored surrounding conditions and ensure that the IoT system can Automate the handling of emergencies. However, the current IoT terminal nodes are usually single-function and low-performance sensing devices, which usually perform networking and data transmission in a wireless manner during large-scale deployment, which brings greater challenges to the design of the entire system. difficulty. [0003] With the development of wireles...
