A Semi-Distributed Reputation Mechanism based on Dynamic Data-Driven Application System

Abstract

Trust is one of the important issues related to unknown networks. A mechanism which can distinguish a trustworthy node from an untrustworthy one is essential. The effectiveness of the mechanism depends on the accuracy of node\'s reputation. Dynamics of Trust often happens in a trusted network. It causes intoxication and disguise for nodes, resulting in abnormal behaviors. This paper proposes a semi-distributed reputation mechanism based on Dynamic Data-Driven Application System. It focuses on the Dynamics of Trust and the balance between Distributed Nodes and the Central Controller. The experimental results show that the proposed mechanism upload only averages 52.21% of the data to compare with all of uploads. It can also effectively handle the problem of Dynamics of Trust.
