In most of the trust models, brokers gain monetary benefit for each of the transactions made through them. This leads to favouritism and bias in the selection of suitable service providers (SPs). This challenge may be overcome by the proposed three-tier framework where regional resource administrators (RRAs), resource brokers and SPs are arranged into three-tiers. The RRAs derive their compensation from registration, renewal and audit charges paid by the broker community, not from individual transactions. In this model, the trust-indices of each of the entities are computed based on the feedback provided by other entities after each transaction. These feedbacks are evaluated by RRAs for genuineness. By doing so, the trust-index of SP is safe guarded against dishonest ratings. These trust-indices of brokers, consumers and SPs are updated dynamically, to ensure trustworthy services. This paper supports the choice of SP based on trust-index with policy-match; thereby the consumer is free from runtime failure.
