Abstract

Service oriented access in a multi-application, multi-access
network environment poses interesting research challenges. One
of these challenges refers to cross-layer interoperability among
technologies. In this poster, we introduce a knowledge base (KB)
which contains local (user terminal specific) knowledge that
enables pro-active network selection by translating technology
specific parameters to higher-level, more abstract parameters. We
implemented a prototype which makes use of semantic technology
(namely ResearchCyc) for creating the elements of the KB: the
ontology, the concepts, facts and rules. The system implements
technology-specific QoS parameters mapping according to the
IEEE 802.21 draft standard recommendation.
