Current aspects of research in communications are manifold. Therefore, the Communication Systems Research (CSG) Group at IFI focuses today on the following topics:
The goal of this area is to develop a model and architecture for multi-provider technical, socio-economic, and regulatory aspects of telecommunications, to provide guidelines and recommendations to European players (end-users, enterprises, operators, regulators, policy makers, content providers) for the provision of new converged services to citizens and enterprises, and to address the high decentralization aspect of multi-player situations.
Current Projects: FLAMINGO, AbaCUS
Past Projects: SmoothIT, EcoNets,Econ@Tel, SESERV
This area addresses the problem of providing necessary architectural and functional features in an Internet-based environment so that networking customers will be enabled to select services according to their needs and will be charged in a fair, incentive-driven manner. Pre-paid mechanisms for All-IP networks and services are under special investigation. A close relation to the work undertaken in the area of distributed accounting can be observed.
Current Projects: AMAAIS, SmartenIT,FLAMINGO, AbaCUS
Past Projects: COST 290, Daidalos II
While Grids need to go mobile, the lack of suitable mechanisms in support of such mobile grid users is obvious, since existing networking mechanisms like AAA, A4C, QoS, and security have not been integrated fully into existing grid models. This work focuses on business flow models and related charging processes for mobile grid services. A close relation to charging and distributed accounting work can be observed.
Past Projects: Akogrimo, BEinGRID, EC-GIN
The application of any network management or charging approach requires in a distributed multi-provider environment a heterogeneous and efficient accounting paradigm to be established. This area addresses interaction schemes, protocols, and parameters for any kind of distributed accounting for Internet services. A close relation with the work on charging and QoS aspects of networks can be observed.
Current Projects: AMAAIS
Past Projects: DAMMO II, Akogrimo, PeerMart, EC-GIN, DaSAHIT, SCRIPT, SESERV
The popularity of P2P has increased dramatically, but security, digital rights management and copy right issues, and market management aspects have been neglected for quite some time. Work in this area targets at suitable models and technology to enable fast and unstructured search as well as charging support for P2P services.
Current Projects: LiveShift, TomP2P, CoopSC,SmartenIT,FLAMINGO

The application of network management mechanisms in the networking domain has progressed in terms of technical approaches very far. However, the integration of economic management mechanisms into existing network management models remains under strong developments. Thus, this work investigates the use of, e.g., session models, pricing models, or business models, within today's management models. Additionally, it considers a fully integrated accounting infrastructure as a basis for all economic approaches.

The use of biometrics for access control has shown until today an almost complete proprietary handling of fixed hardware-software pairs. Thus, the design and development of a operating system-independent, decentralized IP-based, and open device-driven management system has been started to ensure a global and secure administration capability.
Past Projects: BioLANCC, BioXes
