针对名誉机制中的一个节点只设一个名誉值产生的"节点名誉值失信"问题,提出一种结合资源类别、钱和名誉值的CMARCH机制,对每个节点的每类资源均设一个名誉值.消费者节点在购买资源时使用该类资源的特有货币付给资源提供者,依据挣得的货币量来决定提供者节点该类资源的名誉值,从而为一个节点挑选某类资源的服务节点提供更大的可靠性和真实性,降低了多付钱率和交易失败率,提高了准确性,同时可以促进P2P文件共享系统中各节点提供资源种类的多元化.理论分析和实验结果表明,CMARCH机制的多付钱率和交易失败率比单纯的结合钱和名誉值的MARCH机制低,且更能保证节点间的成功交易.

This paper proposed a CMARCH reputation mechanism, which is a combination of Category, Money and Reputation sCHemes, in order to solve the "node reputation's credible lose" brought about from only one reputation value corresponding to a node. In this mechanism, consumer node pays the resource provider through a special "coin" under its resource control, and the provider node's resource reputation value will be increased by the amount of the incoming "coin". All these functions will provide a greater reliability and enhance reality in selecting resource provider node. The mechanism reduces the "overpaid money ratio" (the total paid money divided by overpaid money) and "failed transaction ratio" ( the total number of transactions divided by the number of failed transaction), and improve the accuracy. Meanwhile, it may increase the node's resource diversity in P2P file sharing system. Analysis and experiments have shown that the overpaid money ratio and failed transaction ratio of CMARCH are lower than MARCH (Money and Reputation sCHemes), which ensures a successful transaction between nodes.
