Abstract:

Because of the inherent characteristics of wireless mesh networks (WMN), the existing trust models are not applicable. This paper proposes a novel subjective logic based reputation model to detect and isolate malicious nodes in WMN. The model can also differentiate between malicious packet drop and the packet drop due to poor link quality. The model is applied to radio-metric ad hoc on-demand distance vector routing (RMAODV)
to obtain a trusted routing T-AODV. Simulation results show that the proposed scheme can effectively evaluate trustworthiness of nodes, resist attacks to some extent and improve overall reliability, robustness and security of the network.

Key words:  wireless mesh networks, subjective logic, security, reputation model, trusted routing
