Abstract:

This paper proposes an incentive mechanism (FPIM) with resisting fraudulent conduct in mobile P2P file sharing system based on the theory of first-price sealed auction. In this incentive mechanism, the node calculates the evaluation of a file resource sharing service based on the resource state, virtual currency of it and the property of file resource, then gives the corresponding price according to the evaluation and game strategy. Through the game analysis, the Nash equilibrium solution of FPIM incentive mechanism is given. In order to suppress the fraudulent conduct of malicious node, FPIM introduces hash function and other security mechanisms to judge the fraudulent conduct of node, and eliminates the impact of malicious nodes on the fairness of the auction process. Analysis and simulation show that this incentive mechanism is able to make rational mobile nodes actively participate in file resource sharing cooperation to maximize their own interests, improve the success rate of file resource sharing cooperation in the whole system, reduce the system's energy consumption, and improve the overall effectiveness of the system.
