Advertisement data management and application design in wbcs

This paper describes the design and implementation of the advertisement data management and corresponding intelligent application for use in wireless billboard channels (WBCs) services in the emerging ubiquitous consumer wireless world (UCWW). Running at the application enabler sub-layer of a WBC service provider (WBC-SP)'s node the advertisement data is formatted by using the abstract syntax notation (ASN.1) and organized into segments to reduce the access time, and thus minimizing the mobile terminal's (MT) energy consumption on this service. The intelligent application is implemented within three tiers of the WBC service layer: a service discovery and maintenance tier acting as a client-server distributed system for data collection and organization; an intelligent application tier holding all business logic and common application programming interfaces (APIs); and a multi-agent system (MAS) tier maintaining the advertisement, discovery and association (ADA) agents' lifecycle, and supplying directory facilitator services and message transport services. The performance evaluation of the proposed data management scheme is performed. Details of the application's architecture are also provided.
