A Negotiation Based Approach for Satisfying the Actor Requirements in Web Services Composition
Yassine Jamoussi, Asma Kerkeni · 2013
Web services composition is a crucial aspect of SOA. The diversity of web services and their composition methods puts heavy demands for satisfying actors involved in the composition process. Actually in SOA, contracts are used to satisfy web service provider and consumer, and manage their relationship. However, contracts are adapted to single web service, restricted to Quality of Service, and fall short to deal with dynamic web services composition process. We propose a negotiation-based approach, for enhancing the actor satisfaction within web services composition, that combines satisfaction notion with a negotiation meta-strategy. The former is used as a negotiation decision-making whereas, the latter guides negotiators to make their decisions.
