Reputation-Aware Contract-Supervised Grid Computing
Service-related information available in current Grid is usually static, limited and self-stating. The lack of evaluation from service cooperators and record of past transactions hinders information sharing, isolates entities and separates related transactions. As a result, QoS (Quality of Service) and QoP (Quality of Protection) are hard to be guaranteed. Inspired by observations from human society, we propose a reputation-aware contract-supervised Grid computing model. The adoption of reputation targets at providing an evaluating mechanism, enhancing predictability from past experiences, promoting efficient, secure and reciprocal cooperation between entities, and forming a benign cycle in Grid computing. And contract is introduced to be a supervising mechanism. By this means, a context sensitive, deception detectable, criteria clear, and bias correctable reputation computing will be achieved. Besides, this scheme also develops some kind of CBR (Case-Based Reasoning) capabilities.
