Modeling Epidemic Network Failures

This paper presents the implementation of a failure propagation model for transport networks when multiple failures occur resulting in an epidemic. We model the Susceptible Infected Disabled (SID) epidemic model and validate it by comparing it to analytical solutions. Furthermore, we evaluate the SID model’s behavior and impact on the network performance, as well as the severity of the infection spreading.

The simulations are carried out in OPNET Modeler. The model provides an important input to epidemic connection recovery mechanisms, and can due to its flexibility and versatility be used to evaluate multiple epidemic scenarios in various network types.
