Problems solved by technology

[0005] In order to solve the deficiencies in the prior art, the present invention provides a node mobility identification response method and system in the software-defined Internet of Things, which solves the problem that the controller cannot maintain the real-time topology of the network due to the high mobility of some nodes in the software-defined Internet of Things. In turn, it leads to control decision-making mistakes that reduce the communication quality of the network and increase the network control overhead;

Abstract

The invention discloses a node mobility identification and responding method and system in software-defined Internet of Things. The method includes the following steps: obtaining a set of candidate high-mobility nodes; generating a historical movement state sequence of the candidate high-mobility nodes; predicting the mobility of the candidate high-mobility nodes at the next moment; and implementing real-time routing decisions on the nodes with high mobility at the next moment. Thereby, the problems that because some nodes in the software-defined Internet of Things have high mobility, a controller cannot maintain the real-time topology of the network, control decision errors are further caused, the communication quality of the network is reduced, and the network control overhead is increased can be solved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a node mobility identification and response method and system in the software-defined Internet of Things. Background technique [0002] The rapid development of information and communication technology has promoted the development of smart devices such as RFID, Bluetooth and embedded systems. These smart devices can communicate with each other through the network, and then complete tasks such as automatic recording and automatic processing, which leads to the emergence of new services and applications. The concept of Internet of Things (IoT) came into being. At present, a large number of IoT devices are connected to the Internet in different ways. It is estimated that by 2020, the number of smart devices connected through the Internet of Things will reach 50 billion. However, because the current IoT devices are often configured according to their specific applica...
