Multi-type malicious program attack and defense method based on nonlinear rechargeable sensor network model

Abstract

The present invention relates to a multi-type malicious program attack and defense method based on a nonlinear rechargeable sensor network model, including: S1, constructing a multi-type malicious program propagation model based on a wireless rechargeable sensor network, the malicious program propagation model is based on logic Sti growth rate as the growth rate of the number of nodes in the wireless rechargeable sensor network; S2, construct the state flow chart of the wireless rechargeable sensor network nodes, and write the differential equations of each state according to the state flow chart; S3, construct the malicious program propagation model The cost function under ; S4, according to the differential equation of each state and the cost function, construct the Hamiltonian equation. The present invention not only further considers the problem of energy consumption, but also introduces nonlinear logistic input and nonlinear infection rate, so as to further conform to the working environment of the actual wireless sensor network.

Description

technical field [0001] The invention relates to the technical field of wireless rechargeable sensor networks, in particular to a multi-type malicious program attack and defense method based on a nonlinear rechargeable sensor network model. Background technique [0002] With the continuous upgrading of the corresponding technology of wireless sensor network, it involves more and more fields, such as military field, medical and health, environmental monitoring, building safety, earthquake monitoring, intelligent transportation, etc., which shows its importance and developability. The traditional wireless sensor network can be composed of nodes that collect surrounding information. Nodes and base stations or remote data centers complete the dissemination of processing information in the form of multi-hops. It is precisely because of the relatively simple structure of the wireless sensor network that once it is attacked by malicious programs without any defense measures, the ma...
