Ambient Networks defines a new kind of network architecture,which embeds support for co operation and competition betweendiverse network types within a common control layer. This unifiednetworking concept can adapt to the heterogeneous environments ofdifferent radio technologies and service and networkenvironments. Special focus is placed on facilitating bothcompetition and co-operation of various market players, by defininginterfaces which allow the instant negotiation of cooperationagreements. The Ambient Networking concept has been developedin the framework of the Ambient Networks project, which isco-sponsored by the European Union under the Information SocietyTechnology (IST) priority of the 6th Framework Programme. TheAmbient Networks project mobilised the work of researchers fromover forty different organisations, both major industrialcorporations and leading academic institutions, from Europe andworldwide.
This book offers a complete and detailed overview of the AmbientNetworking concept and its core technologies. The authorsexplain the problems with current mobile IP networks and the needfor a new mobility-aware IP-based control architecture, beforepresenting the Ambient Networking concept itself and the businessopportunities that it offers. The architecture, components,features and challenges of Ambient Networking are covered in depth,with comprehensive discussions of multi-radio access, genericAmbient Network signalling, mobility support, context and networkmanagement and built-in media delivery overlay control.

Ambient Networks: Co-operative Mobile Networking for theWireless World
* Explains the need for Ambient Networking, discussing thelimitations of today's proposed architectures, and explainingthe business potential of edge networks and networkco-operation.
* Describes Ambient Networking technology in detail, andaddresses the technical challenges for implementation.
* Includes practical user scenarios which are fully analysed andassessed through simulation studies.

Including a complete examination of the research andtechnologies arising from the Ambient Networks concept, AmbientNetworks will be invaluable for research and development teamsin networking and communications technology, as well as advancedstudents in electrical engineering and computer sciencefaculties. Standardisation specialists, research departments,and telecommunications analysts will also find this a helpfulresource.
