How to build a resilient system

Abstract

With the population of computers and high-speed development of network, people manage to conduct activities on various areas by using network. The complex network is short of security and easy to be crashed under attacks because of its unique structure. Plenty of studies have shown that attacks on some important nodes of network cause huge damage. Hence, designing resilient networks has increasingly become an important issue.

A resilient system enables the network comes back quickly from any failure. To repair complex networks under attack more efficiently, the repair strategy under attacks should be investigated. In this paper, two repairing strategies under intentional attack have been proposed. The repairing model of complex network is established on the platform of C language programming. Take scale-free networks (BA model) as an instance, the effectiveness of this two repairing strategies under intentional attack is studied by simulation.
