| 摘 要： | 针对对等网络中的文件污染问题，提出一种基于免疫克隆的拓扑构建方案来抑制污染传播。通过分析文件对象的污染传播模型，借鉴免疫学习的思想，优化网络中的节点连接。仿真实验表明，该算法可增加节点的集聚性，能够以较低的通信代价对恶意节点进行有效屏蔽，抑制污染文件在共享网络中的传播，提高对等文件系统的可用性。

| Abstract: | Aiming at the file pollution problem in Peer to Peer（P2P） network,a topology building scheme is proposed to contain the spread of pollution based on immune clone topology.By analyzing the propagation model of file pollution,a neighbor nodes selection algorithm is proposed based on immunity.Simulation results show that the algorithm increases the clustering of nodes,and it can shield against malicious nodes with lower communication costs and control the spread of the pollution file in P2P network.It improves the availability of file system. |

| Keywords: | file pollution topology construction availability Peer to Peer（P2P） network file sharing |
