Analysis of hybrid immunization strategy in complex networks

In this paper, based on the classic SIR epidemiological model, we consider introducing hybrid immunization strategy including targeted immunization and acquaintance immunization to research on the proportion of infected nodes when the spreading of disease ends and the time steps of disease spreading. We use Monte Carlo numerical simulation in this paper, and compare the result with that of single targeted immunization strategy and single acquaintance immunization. It can be concluded from the research that in hybrid immunization strategy, the influence of targeted immunization is greater than acquaintance immunization, and the image curve of simulation result is closer to that of single targeted immunization strategy.
