在Ad Hoc网络中，自私节点的存在会导致数据链路的断裂，影响网络的安全性。针对该问题，在欺骗检测系统(CDS)的基础上，提出一种自私节点检测系统。使用信用保证网络的公平性，根据节点的会话报告构造会话链表集合，通过分析会话链表检测网络中的自私节点，克服CDS对特定类型路由协议的限制。仿真结果表明，该系统能较为准确地识别自私节点，使网络吞吐率逐渐恢复到正常水平。

In Ad Hoc networks, selfish nodes may break the communication links, which affects the network security. Aiming at this problem, a paper proposes Selfish Node Detection System(SNDS) based on Cheating Detection System(CDS). SNDS uses credit to ensure fairness, constructs session links according to reports and detects selfish nodes through analyzing session links. It overcomes the restrictions of specific routing protocol to CDS. Simulation results indicate that, this system can accurately detect the selfish nodes, and makes the network throughout rate return to normal.
