The Ambient Networking concept has been developed in the context of Ambient Networks project, sponsored by the European Union under the Information Society Technology (IST) priority of Framework Programme 6. The authors explain the problems with current mobile IP network architecture and the need for new mobility-aware IP-based control, before presenting the concept of Ambient Networks itself and the business opportunities that offer. Architecture, components, features and challenges of Ambient Networking are covered in depth, with comprehensive discussions of multi-radio access, generic Ambient Network signaling, supporting mobility, context and network management and built-in media delivery overlay control. Ambient Networks: Co-operative Mobile Networking for the Wireless World Describes the need for Ambient Networks, discusses the limitations of today's surgery? S proposed architecture, and explains the business potential of edge networks and network co-. Including a complete examination of research and technology arising from the Ambient Networks concept, Ambient Networks will be very valuable for researchers and development teams in networking and communications technology, as well as advanced students in electrical engineering and computer science faculty.
