P2P网络中恶意节点控制算法的研究
Research on Malicious Nodes Control Algorithm in P2P Network
摘要
Abstract
Based on the research of the current trust models in P2P network, this paper finds the shortcoming of the malicious nodes in the current models, the malicious behavior of these malicious nodes is analyzed, the advantages of many other models are integrated, according to the principle of "slow raising and fast descending" and direct trust has greater impact, especially considering the control of some malicious nodes, one new trust model is put forward. In this model, the trust value is related to the size of the resource after each transaction. Simulation experimental result shows the validity and superiority of the new model, this model can make the transaction success rate enhance greatly.关键词
