Description
Fast and Efficient Context-Aware Services gives a thoroughexplanation of the state-of-the-art in Context-Aware-Services(CAS). The authors describe all major terms and components of CAS,defining context and discussing the requirements of context-awareapplications and their use in 3rd generation services. The textcovers the service creation problem as well as the networktechnology alternatives to support these services and discussesactive and programmable networks in detail. It gives an insightinto the practical approach followed in the CONTEXT project,supplying concrete guidelines for building successful context-awareservices.
Fast and Efficient Context-Aware Services:
* Provides comprehensive and in-depth information onstate-of-the-art CAS technology.
* Proposes a system architecture for CAS creation and delivery,discussing service management and active network layers.
* Describes the service lifecycle functional architecture, coveringservice authoring, customization, invocation, and assurance.
* Explains system design considerations and details, systemevaluation criteria, test-bed requirements, and evaluationresults.
Fast and Efficient Context-Aware Services is an invaluable resourcefor telecommunications developers, researchers in academia andindustry, advanced students in Computer Science and ElectricalEngineering, telecoms operators, as well as telecommunicationmanagement and operator personnel.
