摘要： 针对无线传感器网络内部不能有效地检测出恶意节点攻击所引发的安全问题，提出一种面向无线传感器网络分层路由的信任模型。该模型能发现来自网络内部攻击的恶意节点并将其排除，提高了无线传感器网络的安全性能。实验结果表明，与TLEACH协议相比，在恶意节点攻击时，该模型的敏感性提高了5%，信任值幅度增加了10%。

Abstract: Since Wireless Sensor Networks(WSN) can not effectively detect security problems caused by the internal malicious nodes, this paper presents a hierarchical routing trust model for WSN. The model can detect malicious attacks from nodes within the network, and exclude it from the network. Hence the security of the WSN is greatly improved. Simulation results show that compared with the TLEACH protocol, the model is 5% more sensitive and the trust value is 10% higher when the malicious node attacks.
