Dr. Bless attended the 4th Interim Meeting of the NSIS Working Group of the IETF from 23rd til 24th of May. Participants discussed several open issues of the currently proposed NSIS protocols (e.g., NTLP, QoS-NSLP, NAT/FW-NSLP). A first NTLP prototype, implemented by Uni Goettingen, was demonstrated, too. The Institute of Telematics has just started to implement some of the NSIS protocols.

Erik-Oliver Blaß presented new results regarding research about feasibility of public-key algorithms in sensor networks. Other interesting aspects dealt at this conference concentrated at the composition and interaction of complex services in ubiquitous enviroments. Also a practical demonstration of a maybe-successor for barcodes was presented that can be evaluated by simple mobile phones.
ICAIL 2005Christoph Sorge attended the ICAIL 2005 (10th International Conference on Artificial Intelligence and Law) in Bologna, a conference at the interface between computer science and law. He presented his paper "Conclusion of contracts by electronic agents".
WoWMoM 2005From the 13th to the 16th of june 2005, the international symposium "World of Wireless, Mobile and Multimedia Networks" (WoWMoM) was held in Taormina (Sicily). A wide diversity of current researches done in the area of infrastructure, ad-hoc and sensor networks were presented and discussed. Peter Baumung from the Institute of Telematics participated at the symposium and presented his work related to reliable multicast in ad-hoc networks.
Kick-off Meeting of the Campus Mesh ProjectOn 26th of June 2005 the kick-off meeting of the campus mesh project took place with Siemens in Munich. A mesh is a wireless network which uses multi-hop communication to connect for example to the internet via a wired access point. The campus mesh project deals with selected problems of mesh networking like routing or quality of service. Therefore the project looks upon meshes as an extension of the IEEE 802.11 standard. At the beginning of the meeting the current proposal of Siemens for WLAN mesh networking which is in response to the call for proposals of the IEEE 802.11s task group was presented. Thereafter the representatives of the universities of Karlsruhe and Munich presented their designed basics for the campus mesh project. In the context of these presentations they went into the requirements that were needed for the application areas routing, quality of service and security in WLAN meshes.
2nd Workshop "Energy and Communication"Michael Conrad attended the second workshop of "Energy and Communication" in Erlangen, Germany and presented the research project SESAM.
RealWSN'05Erik-Oliver Blaß presented new ideas for an efficient key establishment in wireless sensornetworks at the RealWSN. Additonally this conference focused on the exchange of experience regarding the deployment of sensotnetworks in real world scenarios.
IST Mobile and Wireless Communications SummitChristian Vogt attended the IST Mobile and Wireless Communications Summit from June 19 through 23 in Dresden. He presented new research results concerning efficient and secure mobility management. The conference's main topics were current challenges and technical progress for IP-based, heterogeneous 3G networks.

Alcatel's UMTS expert Mr. Sigle gave a guest lecture in the course Mobile Communications on May 24, 2005. He explained the high-speed technology "High Speed Downlink Packet Access" (HSDPA), an approaching extension to UMTS. Mr. Sigle put particular emphasis on the current status of implementation and deployment efforts, and he identified the issues that system engineers are facing now or have successfully solved in the past. Students showed great interest in the subject and attended vividly to the discussion following the presentation.
Since the beginning of 2005 the Institute of Telematics is involved in a new project with the name SIMON. The focus of this project is the efficient and fast engineering of software for a organic system. During the two years of duration the itm will focus on security components, the underlaying Ad-Hoc communications, monitoring, and the demonstrator including sensors.
The ScaleNet ProjectThe BMBF founded project "ScaleNet: Scalable, efficient and flexible next generation converged mobile, wireless and fixed access networks" with a term of three years has started in July. Together with seven partners the Institute of Telematics is going to design a system, that offers the possibility to integrate different wireless and fixed access networks and technologies in a scalable, cost-saving and efficient way. The system should be high-performance in all areas and support various forms of mobility. One of the main research areas of the Institute of Telematics in this project will be the use of overlay networks to launch novel services in heterogeneous networks in a flexible and cost-saving way.
Ingmar Baumgart finished his master thesis "Analyse, Optimierung und Evaluierung eines sicheren verteilten Dienstverzeichnisses für drahtlose Sensornetze" at 30.04.2005. The thesis analyses the Secure Content Addressable Network and presents a novel concept for key exchange in sensor networks. Ingmar Baumgart simulated the Secure Content Addressable Network in GloMoSim
New Scalable Simulation Model for IEEE 802.11 in OMNeT++In his master thesis, Georg Lutz developed a generic simulation model for radio interfaces in the forth generation of mobile networks. This model will be used in the context of the research project WIGWAM in order to investigate large, heterogeneous access networks. Therefore, the scalability of the model is of special importance. Besides the generic model, Mr. Lutz exemplarily implemented IEEE 802.11b in OMNeT++ in a more efficient way. His implementation is about 100 times faster than the two existing models.
SAVE-Sender Address Verification ExtensionMatthias Merz finished this Studienarbeit at 30.04.2005. He designed and implemented the SAVE-System. SAVE avoids unwanted eMails. It uses a novel security approach. One of the advantages of SAVE is that it can be used by either a mail server provider or a user. SAVE protects immediately because it does not rely on any infrastructure.
On 17.3.2005 an in-place upgrade of the existing Windows NT Domain to a Active Directory based Windows Server 2003 took place. To be able to perform an in-place upgrade, first a Windows NT Server on modern HW had to be installed, an promoted to PDC. After the upgrade, a second Server -- the new File-Server -- running Windows Server 2003, was installed. Currently the domain is run in mixed mode (there is still one active NT Server).
