Trust Evaluation Model Based on Opportunity Cost in P2P Networks
In the past trust model, fraud and cooperation cheating of malicious nodes were restrained by reducing the trust value of malicious nodes, but few recommendation nodes for cooperation cheating have be punished, so it has had only limited that malicious recommendations or fraudulent actions were taken place again and again. Due to lack to punish to malicious recommendation of recommendation nodes, enormous malicious recommendation nodes remain and search next criminal opportunity constantly. This paper proposed a trust evaluation model based on opportunity cost in p2p networks, which reduces recommendation nodes of cooperation cheating by competition and incentives principles, and which let recommendation nodes are unwilling to fraud and cheating by using objective method, and restrains effectively questions of malicious recommendation and cooperation cheating.
