Center of Competence for networks and distributed systems (CECNDS)

Networks and distributed systems are an essential medium for innovation in nearly all areas. This is especially true for the research profile of the Frankfurt University of Applied Sciences in the areas of "mobility and logistics", "renewable energies" as well as "demographic change and diversity". Therefore the occupation of  the cross section topic "networks and distributed systems" by researches of the Frankfurt University as a competence center is welcomed by the university management, says the vice-president Prof. Dr. Ulrich Schrader. Ranging from intelligent traffic infrastructure to Supply Chain Management and Smart Grid up to Ambient Assisted Living: most of the innovations in these areas are unimaginable. The competence center for networks and distributed systems bundles the research and development activities of seven research groups of the Frankfurt University in this area. This promotes a close link inside the university and with our external partners.

Focusing this the strategy of the competence center is to optimize and synergize the potential of single research areas in cooperation with the other research areas of  the location, bundling resources and competencies consequently.

The competence center for networks and distributed systems of the Faculty 2 consists of several scientists and students. Our projects are centered around forward-looking problem solutions as well as the usage of new ideas in practice.

We are engaged in the education of talented scientists and the creation of multidisciplinary oriented doctorate  networks.

Based on the transfer of abstract research results into practical application the successful transfer of developed future oriented innovative technologies is our focus. Enterprises of all sizes as well as cooperation with public institutions and other universities support us in research. This intensive dialog with project partners in the field delivers valuable scientific-technical innovations. The continuous integration of the enterprise partners ensures practically relevant solutions and transfers according market requirements. Resulting outcomes in the form of products and services can be incorporated in technologies, processes and methods making the contractor competitive in the global market. In this way our projects deliver a high benefit for all project participants and contribute to the strengthening of the Hessian area.

The Research group for Network Security, Information Security and Privacy researches and develops secure technologies for the next and after next generation. The group currently comprises six scientists, supported by numerous students. The focus of the projects is dealing with network- and system security, organization of security, security assessment and –management, reliability and availability of complex systems, network management as well as technical data privacy.

Cooperation partners are enterprises of any size as well as public institutions like the German Federal Office for Information Security (BSI). The  VAIR-Tool, used for the assessment of infrastructure availability in computation centers was developed together with the BSI. The development of innovative future technologies is focused as well as the successful transfer into practice.

The DaNe project developed a market-ready software allowing small and medium-sized enterprises to handle the secure and data privacy compliant operating of their IT-infrastructure by themselves. As a mediator of abstract research knowledge into practical application the research group develops technologies, processes and methods which make the contracting authority competitive in the global market.

The research group for Operating Systems and Computer Networks deals with the issues of real-time communication and development of analysis tools for Java development (JVM). The group consists of three student assistants, who are supported by four students.

In cooperation with the German Telekom (Deutsche Telekom AG) the students projects are used for the development of prototypes and demonstration systems. These projects offer a particular chance for the students to work within a team being a real industrial project.  Results and lessons learned from these projects are directly transferred in the research contexts as well as the finding of new solutions.

Mobile computing i.e. using networked (mobile) computers and sensor data, which generate information from the environment, play an increasing role in (applied) computer science. The research group Mobile Computing examines the practical use of these technologies and relevance for (distributed) algorithms. Topics include location-based services, security aspects of mobile computing, distributed systems (including peer-to-peer), Software Engineering for Embedded Devices, (application) protocols, binding of backend services and integration with Social Networks. Focus of the activities are not only innovative developments of new technologies but rather their successful transfer into practice.

In addition the research group still being build up, is also working together with the center for logistics, mobility and sustainability (Zentrum für Logistik, Mobilität und Nachhaltigkeit or ZLMN).

The research group for telecommunication networks explores the future of communication networks (Next Generation Networks), the intelligent power grids and buildings (smart grid, smart home) as well as the IP-based networking of machines and equipment (Machine-to-Machine Communications).

The current work focuses on "value added services", "systems and network architectures" and "platforms and services." The research and development activities include the full cycle from the requirements to the concepts and realizations through to evaluation and testing.

The objective is to offer optimized, affordable and future-oriented solutions for communication looking to services and networks from suppliers and users point of view.

Wireless sensor networks, especially coupled to mobile devices such as Smartphones, provide for many applications a flexible alternative. Focus of research and development projects of the research group: Wireless and Smart Sensor Networks are used as wireless measurement systems with long range for environmental measurements and as Body Area Networks for measuring medical parameters. In both cases the analysis and visualization of acquired data in distributed systems is part of the R&D work. Various sensor data fusion architectures are investigated to combine different sensor data information. Wireless Sensor Networks and Smart Sensors are building blocks of the Internet of Things.

The paradigm of cloud computing has risen in the past two years with impressive speed in the first place of IT charts. The cloud research group opens up new ways to run applications dynamically and thus reduce capital and labor and energy costs. Cloud Computing concentrates hard- and software in very large computing  centers and are merchandized via the internet. Profitable businesses were  developing in the internet around newly created dynamic IT-services.

Hybrid mobile communication networks integrating different access technologies as WLAN, GSM, UMTS, etc. will allow better network coverage and higher data rates with lower costs. The existing network infrastructure will be used more efficiently. The challenges for the development of hybrid networks are network security and handover from one access network to another. Novel handover methods to establish secure connections in hybrid networks will rely on location information. Therefore a fast and reliable localization is needed protecting the privacy of the users and their position. In addition, these handovers can be used at high speed, e.g. in high-speed trains. Thus, communication in transportation systems is another important topic, where tailored network solutions will be developed using wireless connections. Our research contributes towards higher data rates, more efficient network usage and better reliability and security of the communication along with lower investment costs for future network development.
