Routing security scheme based on reputation evaluation in hierarchical ad hoc networks. (English) Zbl 1208.68067

Summary: We propose a new routing security scheme based on reputation evaluation to meet security requirements in hierarchical ad hoc networks. In this model, the reputation relationship is defined in consideration of the related node roles and functions, while the reputation evaluation mechanism is built based on the correlation among nodes that need to be evaluated. The dynamic reputation threshold is used to improve routing security with the precondition of usability. The reputation information of nodes is updated with different roles. We can reconstruct the route to solve attack problems in transmitting packets. Simulation results show that compared with traditional reputation evaluation models, the proposed model in this paper can more timely and accurately reflect security status and execute improved routing when there are malicious nodes in hierarchical Ad Hoc networks.
