Intelligent Software Architecture for the Service Layer of Wireless Billboard Channels

This paper proposes an intelligent software architecture for the service layer of wireless billboard channels (WBCs), which facilitates the IP datacasting (IPDC) of services´ advertisements in a ubiquitous consumer wireless world (UCWW). The new WBC service layer´s architecture consists of three tiers: 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 tier maintaining the advertisement, discovery and association (ADA) agents´ lifecycle. A message channel, a blackboard and a gateway agent are shared by all three tiers thus enabling ADA processing in a highly efficient way.
