A Multilateral Agent-Based Service Level Agreement Negotiation Framework

Negotiation gets more interesting With the increasing demand for discovering web services. Negotiation requires that the non-functional consumer requirements have to meet with providers. Conducting a negotiation between participants is the key issue for reaching an agreement between them. Service Level Agreements (SLA) plays an important role in service-based systems. Different researchers conduct different bilateral negotiation frameworks. Multilateral negotiation helps the consumer to get the best suitable provider not to get an agreement between agreed participants. This paper presents a multilateral SLA negotiation framework for non-functional requirements using three different functions with time-based strategy. That is for getting the best suitable provider for a consumer. Through the proposed framework, a model is defined to map attributes of participants to a main parameter used in decision-making model. A prototype of the proposed framework is implemented with conducting a multilateral negotiation scenario. The proposed framework reached the best-suitable provider, not an acceptable one.
