Context Broker InterfacesFast and Efficient Context-Aware Services gives a thorough explanation 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-aware applications and their use in 3rd generation services. The text covers the service creation problem as well as the network technology alternatives to support these services and discusses active and programmable networks in detail. It gives an insight into the practical approach followed in the CONTEXT project, supplying concrete guidelines for Wiley series in communications networking & distributed systems.Computer interfacesComputer network architecturesComputer interfaces.Computer network architectures.006.3658.812Raz Danny1715406MiAaPQMiAaPQMiAaPQBOOK9910830287503321Fast and efficient context-aware services4109999UNINA
