Rhymend 12 2013 12 12 Service Level Agreements plays a major role in pervasive applications. In pervasive computing, trust Management is an important issue where consumers and providers are distributed geographically across autonomous domains. In reputation based trust models, the communication between provider and consumer is established by computing trust index obtained from neighboring entities. This involves many numbers of transactions. In this paper, using policies both consumer and provider exchange their policy information prior to communication. This work also addresses the establishment of trustworthiness of the entities and proposes SLA based trust model. The proposed model is shown to be robust in terms of selection of suitable trustworthy provider, elimination of false feedback to safeguard provider’s trust-index and improve job success rate for the consumer community.
