Abstract:

On the basis of comparing the characteristics of different strategies in homogenous networks in terms of efficiency, cost and robustness, the authors constructed a hybrid interdependent network and analyzed the efficiency of different immunization strategies in such network. The results show that although current immunization strategies can effective restrain virus propagation in homogeneous networks, the efficiency of strategies should be improved in interdependent networks.
