A Comprehensive Trust Model for Improved Reliability in Grid

Grid computing and its related technologies will only be adopted by users, if they are confident that their data and privacy are secured and the system is as scalable, robust and reliable as of their own in their places. Trust and reputation systems have been recognized as playing an important role in decision making in the internet. Reputation based systems can be used in grid to improve the reliability of transactions. Reliability is the probability that a process will successfully perform itʹs prescribed task without failure at a given point of time. Hence ensuring reliable transactions plays a vital role in grid computing. To achieve reliable transactions mutual trust must be established between the initiator and the provider. This paper aims at providing a robust and reliable model by eliminating the feed backs of the entities which are not having any compatibility with itʹs own evaluation procedure, This model further applies two way test criteria for initiator and provider and also includes new expression for measuring direct trust.
