Abstract: The article summarized security issues and trust management in mobile Ad Hoc network environment. Based on several currently popular trust models, this article studied and analyzed the advantages and disadvantages of each model, proposed an improved clustering trust model, which is of scalable, dynamic, and initiatively finding out wrong nodes, then, using NS2 simulation platform to simulate the model, compared and analyzed the results in the network performance. The results show the improved model is effective.
