| 摘 要： | 目前，随着规模的不断扩大，很多网络呈现出了“无尺度”的特性。然而，无尺度网络有其特有的脆弱性，如果网络的集散节点遭到攻击，网络将很容易崩溃。文中提出了基于冗余链路的无尺度网络拓扑结构优化算法，将集散节点的邻接网络构造成环形立交结构，保证剩余网络节点间的通信。仿真结果表明，该算法能够较好地提升网络的抗攻击能力。

| Abstract: | Nowadays, with the enlargement of size, many networks present a characteristic called ‘scale-free＇ However, the scale-free network is quite fragile, and if the nodes with most degrees are attacked, the whole network would be crippled. In this paper, a algorithm which optimizes the topology of the scale-free network with redundant links is proposed, and the adjacent networks of the key nodes are linked as a rotary interchange structrue, thus to ensure the communication of left nodes. Simulation indicates that this algorithm has improved the anti-attack capability of the network. |
