PROXY AGENTS FOR ADAPTIVE DELIVERY OF MULTIMEDIAa
Keywords:
Context awareness, Content Adaptation, Multimedia deliveryAbstract
Adaptive delivery of multimedia means the capability of adapting content exploitation according to available resources, session parameters and user profile, in order to improve quality of service. It can be exploited to support people with disabilities in accessing available services, or to change the way of exploiting a resource according to working conditions. For example a text document can be delivered as audiostream when an user is driving, or when it cannot exploit a content as it is, because he is blind. Different kinds of multimedia fruition allow also to conceive new value added services and new models of interaction with contents. Here we present architecture design, and prototypal implementation, of a framework that can be integrated, transparently, in web applications, to add mobile agents based adaptive delivery. Mobile agents technology has been exploited to augment flexibility of classical solutions and to develop advanced facilities. We set up a case study on semantic and location based information retrieval to demonstrate effectiveness of our approach.
