Optimization method for improving robustness of topological structure of Internet of Things

Abstract

The invention relates to an optimization method for improving the robustness of a topological structure of the Internet of Things, and the method comprises the steps: selecting a network Motif which accords with four nodes from an initialized topological structure of the Internet of Things as a minimum operation unit; then selecting all minimum operation units with reconnectable edges from all the minimum operation units as operation units; changing edge connection relations of the part of the selected operation units for a plurality of times, wherein changing operations each time are not completely the same, so that a plurality of new Internet of Things topological structures are obtained; forming a population by the plurality of new Internet of Things topological structures, and constructing a robustness measurement index, using a distributed artificial immune optimization algorithm to optimize each new Internet of Things topological structure in the formed population; and using the corresponding Internet of Things topological structure with the optimal robustness measurement index as the optimal Internet of Things topological structure to be output, so that the malicious attack resistance of the Internet of Things topological structure is effectively improved.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an optimization method for improving the robust performance of the topology of the Internet of Things. Background technique [0002] As a complex complex integrating multiple disciplines and an important supporting part of building a smart city, the Internet of Things is constantly integrating into various fields of society, and is playing an increasingly important role in realizing the Internet of Everything. [0003] The Internet of Things usually has a data service center and a large number of monitoring devices (such as sensors). A variety of application scenarios provide high-quality services. Wherein, these monitoring devices are arranged in the Internet of Things in the form of topology, that is, the monitoring devices are distributed in different positions in the Internet of Things in the form of topology, and the Internet of Things used in different application sce...

AI Technical Summary

Problems solved by technology

When using the monitoring equipment arranged in the existing Internet of Things topology to transmit data to the data service center in the Internet of Things, the current network topology has low robustness and cannot support the transmission of large amounts of data, especially in the network topology When the structure is threatened, it is even more difficult to ensure the efficiency and security of large amounts of data transmission
