„High Dynamic Networks “ Emergency Response Mgmt. / Wireless Robotics

Highly mobile communication notes and unpredictable network topologies require more and more intelligent algorithms and protocols for situation-and application-aware communications. On the one hand such networks are highly dynamic and characterized by perpetually divergent requirements on the communication link, such as data rate and delay. On the other hand the underlying circumstances of high dynamic networks, such as network coverage / signal strength, relative speeds of communication instances, the capacity and availability of network access points, are varying.

An important application field of highly dynamic networks can be found in the area of emergency information management as well as in the field of machine-machine communication (robotics). Current research topics in this area are:

• Dynamic Network Planning and Mobility Modeling for autonomous Micro Unmanned Aerial Vehicles (UAV)
• Coverage Optimization using Swarm based Team Strategies on UAVs
• Network Security and Vertical Handover Methods for Distributed Safety-Critical Emergency Information Systems
• Fast Mobile IP for Vertical Handover Support in IPv6 based Networks
• Geo-based Routing Concepts and Mobility Strategies for High Vehicular Embedded WLAN Networks
• Adaptive Quality of Service Algorithms and Channel Modeling for Mobile WiMAX and E-UTRA (LTE) 
• Next Generation Public Safty Mobile Networks for public safty and disaster recovery (PSDR) organisations based on Trunked Radio (TETRA)
• Service Architectures and Middleware-Development for XML based IT-federations
• Efficient and secure naval Federation Technologies

 

„Highly Reliable Networks“,  Wireless Automation and Navigation for Energy and Production Systems

(coordinator: A. Lewandowski)

 

The development of wireless communication technologies opens the way for new application areas for Energy and Production Systems. A reliable and error free connection is essential for safe operation of industrial processes and energy supply. If highly reliable wireless networking can be achieved for these time critical and safety-relevant processes, costs of maintenance and installation will be saved in comparison to wired solutions.

Wireless networks in this application area usually consist of stationary backbone nodes and a number of resource constraint and mobile devices, which are exchanging relevant sensor measurements, sending and receiving control commands, transfer billing data and handling user interaction. Coverage, Energy Consumption, Data Rates, Reliability, Availability and Latencies are all areas of research in order to enable highly reliable communication processes. Thinking of the application scenario "Monitoring of safety critical processes in industrial environments" and "E-Mobility", geo-information is a central requirement for information processing. Highly precise localization techniques for indoor and outdoor scenarios are also evaluated:

• Reliable and Scalable ICT Solutions for Future Energy Trading Platforms
• Web Services for Devices and Wide Area Service Provisioning for the Internet-of-Things
• Evaluation and Optimization of Enabling Communication Technologies and Protocols for Scalable Industrial Applications
• Monitoring of Industrial Processes and Indoor Localization using ZigBee Networks
• Optimizing the Energy Consumption of Autonomous Sensor Networks with intelligent Communication Protocols
• Channel Modeling and Development of Novel Communication Services for Satellite Networks   
• Employment of Galileo Services in Disaster Control
• Queueing Theory for Resource-Constrained Communication Networks
