A New Resource Pricing Fluctuation Model with Trust System in Grid Economy

In recent years, the study of the grid economy is becoming a new hot spot with the grid technology development. Lots of models and middleware have been proposed by scholars to improve the application of grid economy. In our previous research work we have proposed the resource pricing fluctuation module (RPFM) as a part of grid architecture for computational economy (GRACE). However, as nodes in the GRACE can access and leave grid environments freely, the trust of nodes become an important issue. In this paper, we propose a trust evaluation module for the RPFM and present a new RPFM with trust system for the GRACE. The simulation experiments reveal the significance of our new proposed model.
