%X In this paper, a dynamic reputation evaluation model is proposed to meet the characteristic and security requirement in hierarchical Ad hoc networks. In this model, the reputation relationship is defined with the consideration of related nodes’ roles and function, and the reputation evaluation mechanism is built based on the correlation among nodes to evaluate and update reputation information of nodes with different roles. The cluster reputation is monitored by the cluster head in this model to solve the slow convergence speed issue in traditional reputation calculation. Simulation results show that, compared to traditional reputation evaluation models, the model proposed in this paper can more real-time and accurately reflect the security status in hierarchical Ad hoc networks.
