A New Resource Discovery Mechanism with Negotiate Solution Based on Agent in Grid Environments

Grid computing is a hot research direction in computer field. Resource management is an important part of this research. In Grid environment, satisfactory services for discovering resources and allocating appropriate resources can be provided to the Grid users though the agents. Agent based resource management with alternate solution (ABRMAS) has been proposed. But the alternate solution is not explicit. This paper adds the middleware grid architecture for computational economy (GRACE) with resources pricing fluctuation manager (RPFM) into ABRMAS. The new model is designed so as to provide negotiate solution when resource discovery fails of nodes occurrence. Through simulation experiments, the system profit and successful rate are all improved by the new model.
