An attack-Resistant Reputation Management System For Mobile Ad Hoc Networks

Due to the openness and dynamics of the network topology, the mobile ad hoc network ( MANET ) is vulnerable to various attacks by malicious nodes. How to effectively collect trust information and select trusted relay nodes for message delivery is the focus of current research. For this reason, the reputation value is proposed to indicate the degree of trust of the node. In this paper, a reputation management system, which composed of the collection of reputation information and the calculation of reputation value, is proposed to deal with the malicious attacks and improve the network efficiency. We proposed a new trust collection mechanism to optimize the efficiency of trust information collection. A node reputation value calculation model is designed based on subjective trust and recommendation trust. Finally, simulation results demonstrate the effectiveness of this model.
