Female CNI Graduate Honored with Award for Valedictorians

sarahgillet

20.12.2013 – The student of Information Technologies Sarah Gillet has been honored with the Award for Valedictorians by the Gesellschaft der Freunde der Technischen Universität Dortmund e.V. for her bachelor thesis with the title „Kommunikationssensitive Navigationsplanung für agentenbasierte UAV Schwärme“ which she conducted at the Communication Networks Institute. The paper was written in cooperation with Prof. Dr. Heiko Krumm (LS IV).

The operation planning of the networked robotic system, which had been investigated as part of the research, is based on decentralized bidding and electoral procedures. Due to the mostly self-organizing manner of the measuring robots, the emergency task force is supposed to be optimally supported in emergency aid operations, for example in order to quickly locate buried people or to measure pollution without endangering the rescuers themselves.

edash

14.11.2013 – On October 24, 2013, the interim results of the EU project e‑DASH - Electricity Demand and Supply Harmonization for EVs which is being supported as part of the 7th Framework Programme has been successfully presented at the Volkswagen Arena in Wolfsburg. In the e-DASH Project, a total of 14 international partners are investigating the implementation of electric vehicle fleets into future European energy grids under the direction of Volkswagen AG.

In the project, the CNI is responsible for the design, evaluation and optimization of a new telematics interface between the electric vehicle and the OEM backend system. This telematics interface is intended to provide valuable information on charging processes in electric vehicles. Aside from an electric vehicle fleet, the provision of balancing energy is to be controlled with the aid of the interface taking into account the requirements of energy grids. For demonstration purposes, a prototype, which had been developed by the CNI, was presented during the 24 months review. This prototype aligns the linkage to such a backend system with standards for charging communication, such as IEC 61851-1 and ISO/IEC 15118. Further information concerning the e-DASH Project is available at www.edash.eu.

27.08.2013 – The Open Source Satellite Simulator (OS³) which was developed as part of the Collaborative Research Center 876 at the Communication Networks Institute has been admitted to the latest version of the INET Framework based on OMNeT++ and is directly available for every INET User from now on.

OS³ can, due to its modular set-up, be modified or applied to satellite-specific problems of ICT. In order to guarantee the accuracy of the simulation, most up to date ephemerides of the satellites and influence parameters of the atmosphere are imported each at the beginning of the simulation. At that, due to an already integrated graphical interface, even inexperienced users are able to tap the full potential of the simulator.
