Control and Research of Computer Virus by Multimedia Technology
Abstract
The rapid development of multimedia technology has brought great changes to people's lives and production. Computer viruses also spread widely through the network. In order to solve the above problems, this article intends to use multimedia technology to control computer viruses, and proposes a virus control method based on SICES model. According to the controlled SICES model and the set objective function, the influence of users' online behavior patterns on virus propagation can be explored, and an optimal control problem is proposed. Through theoretical analysis, the existence of optimal control is proved, and the optimal system is obtained. Numerical experiments show the effectiveness of the optimal control strategy. In addition, in order to optimize the objective function to make its value smaller, and to control the proportion of infected nodes at a lower level, users should choose the corresponding online behavior mode according to different network structures. For example, on the WS small world network, the network should be frequently disconnected or always kept online.
