Abstract
The provision of Service-Based Applications (SBAs) will be driven by market-oriented mechanisms, and the market value of an application will depend not only on its functionality, but also on the value of "quality of service" (QoS) parameters affecting its performance. These parameters are not static properties since they may vary according to the provision strategies of providers as well as the demand of users having their own preferences on the application's QoS values. In this paper we propose a market-based negotiation mechanism among service providers and a user requesting a QoS-aware SBA. It allows to take into account the variability of service QoS attribute values typical of the future market of services, as well as to dynamically set the length of the negotiation process that is usually very time-consuming especially in the context of on-demand applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
