On WBC Service Layer for UCWW

This paper describes the main service layer´s elements of wireless billboard channels (WBCs) used for service advertisement and discovery in the ubiquitous consumer wireless world. (UCWW). The WBC service provider´s central node works as a multi-agent system (MAS) for collecting, clustering, scheduling, indexing, and encoding of service descriptions (SDs). After receiving the needed SDs and based on the user profile and terminal´s composite capabilities/preferences profile (CC/PP), the terminal discovers the ldquobestrdquo services in each category and associates with them in an intelligent way.
