Reputation based trust model for grid with enhanced reliabilty

Abstract

Grid computing is a next evolutionary level of distributed computing. It integrates the users and resources which are scattered in various domains. The Grid and its related technologies will be used only if the users and the providers mutually trust each other. The system must be as reliable and robust as of their own. The reliability can be defined as the probability of any process to complete it's task successfully as the way it was expected. In grid the reliability of any transaction can be improved by considering trust and reputation. Trust depends on one's own individual experiences and referrals from other entities. This paper proposes a model which improves reliability in grid by considering reputation and trust. © Springer-Verlag Berlin Heidelberg 2011.
