Abstract: In order to eliminate the influence caused by the interference of invalid node collusion attack, obtain a more effective method for eliminating invalid nodes, a novel eliminating method of network invalid node is proposed in this paper based on credibility scheme. Firstly, we analysis the basic structure of invalid node elimination based on credibility scheme and opinion distance-based reputation evaluation model (ODRE) is proposed. According to the communication signals between nodes, the concept of node credibility is updated. Avoid collusion attack of invalid nodes, concept distance is adopted to implement on the recommended concept and eliminate the invalid views. Based on the reliability of the credibility concepts, invalid nodes are detected and excluded. Simulation shows that this method used in eliminating invalid nodes is reduced by 38% without attack, which indicates that the proposed method has higher probability of constraining the invalid nodes collusive attack node.
