A Multi-granularity Reputation Management Model Suitable for P2P MMOG

In order to solve the problem of the lack of fairness and poor security in online games, this paper presents a multi-granularity reputation management model for P2P MMOG. In order to accurately evaluate the reputation of the different roles of the games players, the model assesses the reputation of different roles taken by players respectively and calculates the player´s reputation by fuzzy theory. This paper also gives the algorithm of reputation evaluation. In addition, this paper introduces the incentive mechanism to encourage players to take the initiative to carry out evaluation on the quality of coordinator service and act as a coordinator. The experimental results show that the multi-granularity reputation can provide a more appropriate credit support in related fields and provide a fair and credible gaming environment for the multi-player games.
