To ensure that the Ambient Networks solution sets new standards for future context-aware, multi-domain mobile networks by addressing the following key issues:
- new algorithms for efficient management of radio resources across different radio technologies and multiple domains to provide efficient and low-cost access, irrespective of administrative boundaries,
- design of an innovative link layer solution for easy adaptation and incorporation of existing and new radio interfaces,
- a protocol suite for network composition ensuring connectivity, resource management, security, manageability, conflict resolution, and content handling,
- support for dynamic agreements that provide any subscriber with access to any network in any place including an end-to-end QoS concept,
- advanced multi-domain mobility management for users and user groups over a multitude of heterogeneous, wireless access networks, including new forms of wireless access networks such as personal area networks or vehicular networks,
- efficient support for multimedia delivery by developing cross-domain media flow routing and transport functionalities, balancing QoS by considering different access technologies, networks, end-device capabilities, and the QoS requirements of different media flows
- context-aware networks to improve efficiency and enable new applications, common, scalable and secure interfaces between network domains,
- innovative self-management not only for new network nodes but also complete newly composed networks.
- To ensure the commercial viability by identifying business roles and interfaces as well as deployment concepts and to consider business scenarios that allow different size and types of players to compete and cooperate and hence enable new business models based on established trust relationships.
- To validate the various technical solutions developed by proof of concept activities in all workpackages.
All work on future networking scenarios emphasises two key issues:
Firstly, networks will become more technologically heterogeneous, accommodating old and new access systems as well as applications and services.
Secondly, networks will become organisationally heterogeneous: today's cellular systems will be complemented by adiverse mixture of other network types - personal, vehicular, sensor,hot-spot and more. And this network of networks will have to form and re-form dynamically in response to changing conditions.
The networking architecture developed in Ambient Networks consists out of the following core concepts:
- Ambient Control Space: Ambient Networks has developed the concept of the Ambient Control Space (ACS), an environment within which a set of modular control functions can co-exist and cooperate. The environment is based on plug&play concepts that allow the ACS to bootstrap and discoverthe set of supported functions dynamically.
- Ambient Layer Model: To define the upper and lower boundaries of the networking functionality, Ambient Networks has developed detailed specifications for a pair of inter-layer interfaces:
- ASI: At the upper boundary, the Ambient Service Interface (ASI) provides uniform access to the Ambient Networks functionality from higher layers,
- ARI: At the lower boundary, the Ambient Resource Interface (ARI) encapsulates the capabilities of the underlying infrastructure, and a flow level abstraction provides the basic building block of data transfer between network addresses.
- Network Composition: The project has developed the concept of network composition as the core approach to achieve the dynamic integration of control functionality - the ACS - across a heterogeneous set of networks. A signalling protocol framework has been developed to support composition negotiation across the Ambient Network Interface
The technical completeness and consistency of the approach have been validated via the modelling of a set of detailed use cases, derived from top-level user scenarios generated at the start of the project.
Finally, the first steps have been taken to move the work beyond the research world, with the development of a 4-stage migration strategy and the initiation of standardisation work items to cover the key concepts in composition and signalling. These results show that the goals set for the first two years of research have been satisfied. Thus, we are confident that this architecture provides a firm baseline for the system development activities which will be the focus of the next phase of Ambient Networks.
