A mathematical model for malware spread on WSNs with population dynamics

The aim of this work is to describe and analyze a new theoretical model to simulate the spread of malicious code on wireless sensor networks. Specifically, this is a SCIRS model such that population dynamics, and vaccination and reinfection processes are considered. The local and global stability of...

Description
Summary:The aim of this work is to describe and analyze a new theoretical model to simulate the spread of malicious code on wireless sensor networks. Specifically, this is a SCIRS model such that population dynamics, and vaccination and reinfection processes are considered. The local and global stability of the equilibrium points are studied and the most important security countermeasures are explicitly shown by means of the analysis of the epidemic threshold. •A novel SCIRS model for malware propagation and considering population dynamics is introduced.•The local and global stability of the steady states are explicitly studied.•Security countermeasures are obtained from the analysis of the basic reproductive number.
