|The Negotiation of Multimedia
Content Services in Heterogeneous Environments
Tayeb Lemlouma and Nabil Layaida
Few number of works have discussed the problem of multimedia services negotiation in heterogeneous environments. This paper presents a new negotiation strategy of services in such environments. This strategy is based on the concept of profiling and document selection. We show how CC/PP-RDF model can be used to describe clients preferences and capabilities, and how SMIL 2.0 modularization can serve as a basis to ensure services profile definition. We give the rules to follow in order to achieve the negotiation task. The negotiation protocol that we propose uses a method of profiling evaluation that we call the TL evaluation. We show how our protocol can respond efficiently to a best deliverance of adapted multimedia services for the end users, while taking into account device limitations and user preferences.
