Abstract: It is the requirement to research data replica storage and management technology for improving the reliability and efficiency of massive data in complex network like the cloud computing. The game theory is used to analyze the replica creation problem, and its basic model in complex network based on game strategy is proposed. The existence of pure strategy Nash equilibria in basic model is proved, and the results are analyzed through simulation. The method is of reference value for improving the usability and efficiency of massive data.

Key words: replica creation, game theoretic, replica creation basic model, transfer cost, pure strategy Nash equilibria, massive data
