Internet-of-things response type bandwidth adjusting method based on forward task estimation

Abstract

The invention discloses a responsive bandwidth adjustment method of the Internet of Things based on forward task estimation. The method includes: forward task estimation, an application layer priority management strategy and a responsive bandwidth adjustment algorithm. Forward task estimation solves the problem of wasting the expected authorized bandwidth at the terminal layer; the application layer priority management strategy is a weight and weight of the influencing factors based on the application layer priority modeling, and then realizes the application of the application layer task priority It not only has programmable input, but also focuses on solving the problem of adaptive adjustment of variable priority tasks; the responsive bandwidth adjustment algorithm provides quality support for the completion of target tasks, and can quickly Adjust bandwidth in response to overall network bandwidth requests. The method has a simple structure, strong overall resource planning, and has no special requirements for network equipment, and is especially suitable for responsive adjustment of narrowband IoT bandwidth with heavy terminal tasks.

Description

technical field [0001] The invention belongs to the field of the Internet of Things and relates to a method for adjusting the bandwidth of the Internet of Things responsively, in particular to a narrowband IoT responsive bandwidth adjusting method based on forward task estimation. Background technique [0002] In recent years, the idea of ​​"Internet of Everything" has been reflected in all aspects of production and life. Due to resource constraints such as on-site conditions, space, time, or cost in ad hoc networks and industrial on-site IoT, bandwidth has become a scarce resource, especially for narrow-band IoT. Networking, usually only more than 100 Kbps, whether the energy-efficient use of precious bandwidth resources to complete on-site tasks determines the network service experience, so the limited bandwidth to achieve responsive bandwidth adjustment of the Internet of Things has become a very critical issue. [0003] Taking the industrial field Internet of Things as a...

Problems solved by technology

[0003] Taking the industrial field Internet of Things as an example, although the terminal tasks and devices of the network are very clear, due to the complex and changeable usage requirements and scenarios, the priority of the same task is dynamically changed, so the line terminal based on the network layer Generic bandwidth allocation strategies of (LT) and network unit (NU) devices are not up to the task of bandwidth regulation in NB-IoT
