| Abstract | Recently, in contrast with the centralized networks(e.g., traditional client/server systems), the distributednetworks such as Peer-to-Peer (P2P) networks and gridnetworks have attracted much attention due to their scalability.While the distributed networks have the advantageof allowing the node(s) to join or leave the network easily,the issue of lack of resiliency to both attacks and faults stillremains. In this paper, we classify the existing distributednetworks based on their degree distributions. Then, wedemonstrate that they are not resilient to attacks and/orfaults. For example, unstructured P2P networks, which havea power-law degree distribution, are vulnerable to attackssuch as DOS. To address and resolve this issue, we proposea method to construct a network following bimodal degreedistribution, which is robust to deal with both attacksand faults. Performance evaluation is conducted throughcomputer simulations, which show that the proposed methodcan achieve higher resilience compared with other existingnetworking approaches. |
