A New Trust Mechanism with Penalty and Bonus Based on Agent in Grid Market

There are much collaboration and cooperation in the dynamic, multi-institutional virtual grid. Grid provides a good bridge between the resource users and the resource providers. Especially in the agent-based grid system, agents could provide services for the scheduling of applications that make grid resources better use. We have proposed a resource discovery mechanism with negotiation in grid environment. However, no trust management strategy has been presented in the previous model, which could not prevent the cheat of malicious nodes in the Grid platform. Therefore, in this paper, we propose a trust mechanism with penalty and bonus and use the penalty and bonus with power functions to realize the honest. Simulation study proves the system profit and honest rate are improved.
