A UTILITY-BASED REPUTATION MODEL FOR GRID RESOURCE MANAGEMENT SYSTEM

摘要: In this paper we propose extensions to the existing utility-based reputation model for virtual organizations (VOs) in grids, and present a novel approach integrating into grid resource management system. The proposed include: incorporation of statistical user behaviour (SMUB) assess reputation; new assigning initial entity VO; capturing alliance between consumer resource; time decay score functions. addition SMUB provides robustness dynamics comparing policy-based terms adapting actions. We consider problem scheduler as multi-criteria optimization problem. A non-linear trade-off scheme is applied form composition partial criteria provide single objective function. advantage using such that it Pareto-optimal solution partially satisfying with corresponding weights. Experiments were run evaluate performance data collected within EGEE Grid-Observatory project. Results simulations showed on average 45 % gain can be achieved when reputation-based scheduling algorithm.
