Best Paper Award for CNI Contribution to the Integration of TETRA and IP Based Cellular Networks

16.11.2011 – For the second time already, the institute's work in the field of developing efficient communication systems for rescue service organizations, such as fire brigades, was honored with a Best Paper Award on the international IEEE Conference on technologies for emergency services. The contribution awarded this year, "Integrated PMR-Broadband-IP Network for Secure Realtime Multimedia Information Sharing" by Sebastian Subik and Christian Wietfeld, introduces a new way of integrating UMTS and later LTE smartphones into secure groups of TETRA-based radio communication for authorities. The paper, which is a product of the SPIDER Project, marks an essential step on the way to equip rescue services with future-proof mobile communications technology.


CNI Introduces Reliable On-Site Communication for Successful Rescue Operation

10.11.2011 – At the practical presentation of the interdisciplinary research project SPIDER on October 22, 2011, the Communication Networks Institute presented the latest research results on networking heterogeneous communication systems. Professor Wietfeld's team presented technical, operational, and management-tactical solutions for major incidents with the aid of realistic scenarios in hall 8 of Koelnmesse - practical and cross-organizational for civil security. The institute's primary focus within the SPIDER Project is the research of innovative technologies for reliable on-site communication.


Successful contribution to IEEE Sensors Journal 2011

01.09.2011 – The manuscript titled “Cognitive Agent Mobility for Aerial Sensor Networks” is accepted for publication in IEEE Sensors Journal 2011 (already available in IEEEXplore). The focus of this manuscript are CNI’s latest research results in the area of communication-aware mobility algorithms for swarm-based Micro UAV (Micro Unmanned Aerial Vehicles) missions. For efficient sensor coverage of large industrial and incident areas, fast and flexible strategies for collecting sensor data through an autonomous, wirelessly connected swarm of (MUAVs) are still an emerging challenge. Deploying multiple MUAVs which stably carry sensing equipment in hostile environments yields cost efficiency and reducing the risk to human life. The use of an aerial ad hoc sensor network based on MUAV agents promises more timely and accurate information by fusing measurements from different types of sensors. In this paper we examine agent-based mobility algorithms that target high spatial coverage distribution, high total coverage and high quality communication links. For these key figures, the performance of the different novel mobility algorithms is evaluated. We particularly focus on channel aware mobility and on self-organizing mesh topologies of MUAV based sensor swarms with respect to communication constraints.


CNI organizes again IEEE Globecom Workshop "Wireless Networking for Unmanned Autonomous Vehicles


23.05.2011 – The Communication Networks Institute (Prof. Wietfeld) of TU Dortmund jointly organizes with the Aerospace Controls Laboratory of the MIT (Prof. How) the second workshop on "Wireless Networking for Unmanned Aerial Vehicles" at the IEEE Globecom 2011 to be held in Houston, Texas, in December 2011. Recent incidents, such as Fukushima or the search for the black box of AF 447 have shown the benefits of unmanned systems for civilian operations. The workshop aims to discuss most recent results of various international research initiatives on new communications networks enabling the efficient operation of teams of unmanned vehicles/systems operating on the ground, in the air, underwater and in space scenarios.


Communication Networks Institute Presents Research Results at Hannover Messe


05.04.2011 – At the fair stand of the Federal Ministry of Education and Research (BMBF) (hall 2, stand C24) at Hannover Messe, the Communication Networks Institute (Prof. Christian Wietfeld) of TU Dortmund together with the project partners ThyssenKrupp, Gesellschaft für Gerätebau and PRO DV Software AG presented the latest research results of the BMBF project SAVE (geographic information system with autonomous, networked gas sensors for alerting purposes).


CNI Participating in New DFG Research Group


04.02.2011 – The requirements for energy grids are becoming more and more complex due to the use of renewable energy sources - and thus the demands on their control, monitoring, and preservation. Now, a new interdisciplinary DFG research group is about to develop innovative preservation and control systems for energy systems, which spread out transcontinentally. At this, Prof. Wietfeld directs two subprojects of the research group, which investigate efficient communication networks and strategies in terms of a real-time capable information and communication technology as well as a new type of hybrid simulator for energy and communication networks.
