Lightening protection internet of things survivability optimization method based on complex network

Abstract

Provided is a lightening protection internet of things survivability optimization method based on a complex network. An optimization design is conducted towards a network topology structure so that important businesses are not affected when the network breaks down. The method is to add a backup link and a backup device to the network and the number of the backup is more than enough. With an adding of the number of nodes or edges to the network, a shortest distance between the nodes can be shortened and a network connectivity is improved so that a working performance can be maintained through other nodes and edges when the network is faced with an attack. Besides, two types of rebuilding connection strategy AIR and AUR are adopted to remove or reconnect a connection between high number and low number nodes according to a presupposed threshold value T. Through optimizing the network topology structure, a communication reliability is enhanced.

Description

technical field [0001] The invention belongs to the technique of optimization method for lightning protection Internet of Things invulnerability, in particular to a complex network-based optimization method for lightning protection Internet of Things invulnerability. [0002] Background technique [0003] Since the birth of the computer, social civilization and economy have developed rapidly, and the network has played an increasingly important role in people's lives. People are increasingly relying on the network, especially the Internet and communication networks. However, various network failures also increase with the continuous complexity and size of the network. At the same time, because more people are connected through the network, the network is facing more severe threats and attacks. If random failures or deliberate attacks occur on key nodes or key paths in the network, and cannot be remedied in time, it will seriously affect network services and cause users to ...

However, various network failures are also increasing with the continuous complexity and size of the network

At the same time, because more people are connected through the network, the network is facing more serious threats and attacks

If random failures or deliberate attacks occur on key nodes or critical paths in the network, and cannot be remedied in time, it will seriously affect network services and cause users to suffer huge losses
