Malware diffusion behavior analysis in the internet and its immune protection strategies
We study the dynamics of epidemic spread in a system of mobile agents, where all agents move within the bounded square on a plane. Each agent moves with the same constant absolute velocity whose direction is updated according to the agents in his sensing neighbourhood. If the distance between a susceptible agent and an infected one is less than a given contacting radius, then the agents are considered in contacts for the spreading of infections of epidemics with the susceptible-infected-susceptible (SIS) model. We propose a control strategy that each moving susceptible agent avoids the infected agents in his sensing neighbourhood. The simulation results show that the strategy can enhance the epidemic threshold and is validated for spreading control.
