Improving brokering adaptation in dynamic heterogeneous environments
by Luis Nogueira, Eugenio Oliveira
International Journal of Product Lifecycle Management (IJPLM), Vol. 2, No. 2, 2007

Abstract: We here present an agent-based Quality of Service (QoS) negotiation framework that enables service providers to negotiate the level of QoS provided to end-users according to its own current state. In our model, end-users' QoS preferences are expressed in service requests along several dimensions. From this set of QoS constraints and information about end-users' devices our service configuration brokering facility is able to create and exploit different users' communities associated with their specific inferred stereotypes, in order to be helpful, in an adaptive way, in a dynamically changing environment populated with previously unknown entities (clients, users, machines, etc.).
