Abstract

Interoperability-centric and loosely-coupled distributed computing environment brings forward a new challenge on trustworthiness of service computing, at the same time, user puts more and more pressure on system's non-functional requirements such as real-time, availability, security, cost and so on. Therefore service's QoS should be guaranteed trustworthily. In this paper a Trustworthy Service Scheduling Framework (TSSF) is presented to guarantee composite service's QoS requirement. The overall QoS requirement of the entire composite service is satisfied with the method of planning and guaranteeing the QoS of each atomic service. Our approach is to decompose the QoS requirement for the composite service into separate ones for the atoms; and then TSSF delivers expected QoS for each atomic service with adaptive trustworthy service scheduling mechanisms based on Dynamic Service Entity Group (DSEG); finally experimental results indicate good performance of the proposed framework.
