Centaurus: a framework for intelligent services in a mobile environment

Abstract

In an age where wirelessly networked appliances and devices are becoming commonplace, there is a necessity for connecting them to work together for a mobile user. The design outlined in this paper provides an infrastructure and communication protocol for providing 'smart' services to these mobile devices. This flexible framework allows any medium to be used for communication between the system and the portable device, including infra-red, and BlueTooth. Using Extensible Markup Language for information passing, gives the system a uniform and easily adaptable interface. We explain our trade-offs in implementation and through experiments we show that the design is feasible and that it indeed provides a flexible structure for providing services. Centaurus provides a uniform infrastructure for heterogeneous services, both hardware and software services, to be made available to the users everywhere where they are needed.

Discovery, monitoring and management in smart spaces composed of low capacity nodes

“…Architectural solutions such as [8], [10] and [11] propose XML based data models for messaging. Many other solutions introduce even more complex data formats for better structure and more expressive power.…”

A Flexible and Accurate Reasoning Method for Danger-Aware Services Based on Context Similarity from Feature Point of View

“…key-value model [7], markup scheme model [8], graphical model [9], object oriented model [10], logic based model [11] and ontology based model [12]- [21]. Ontology based context model has been shown to be the most effective one with variety of reasons, e.g.…”

“…The ontology based context model has been used in many context-aware systems, e.g. CoBrA [12], [13], Gaia [14], [15], GLOSS [16], [17], ASC [18], [19], CONON in SOCAM [20], and GAS [21].…”

“…CoBrA [12], [13], Gaia [14], [15], ASC [18], [19], and CONON in SOCAM [20]. The Context Broker Architecture (CoBrA) is a broker-centric, agent-based architecture to support context-aware computing systems.…”

Intelligent Agents Meet Semantic Web in a Smart Meeting Room

“…Speech Recognition Service This service can be invoked to perform speech recognition on a set of predefined voice input vocabularies (e.g., "yes", "no", "show Harry's presentation") and generate CCML (Centaurus Capability Markup Language) [14] commands for controlling other Vigil services. In this service, the underlying voice recognition procedure is implemented using the IBM WebSphere Voice Server SDK and Voice XML.…”
