A Simple Diffusion Model for Assessing the Effects of Attacks on Networks Partitioned in Communities
Descripción
This paper presents a first approach based on a simple diffusion model for evaluating the security characteristics of a system exposed to a random or intentional attack. The physical system is modeled as a network that is previously partitioned in communities. A simple diffusion model, based on cellular automata, is employed to describe the dynamics of spread of the hazard through the network while a Monte Carlo simulation allows simulating the stochastic evolution of the hazard between the nodes of the network. The assessment includes the behavior of the diffusion on each community as well as on the system. Two criteria are used to assess the security characteristics of the network: the First Time to Affect a Community and the Time to Reach a Percentage of Nodes of a Community. Two examples, using topologies of real electric power systems, are used to illustrate the proposed approach.
