Durch verschieden stark abstrahierte Modelle lassen sich auf diese Weise, bereits früh in der Entwicklung verteilter Systeme, Aussagen über Performanz, Konsistenz und Korrektheit von Netzwerkprotokollen treffen. Diese Verfahren arbeiten auf explizit für den Testvorgang entworfenen Modellimplementierungen, welche zwar teilweise Quelltext mit der Produktionssoftware gemein haben, aber viele Aspekte und potentielle Fehlerquellen einer tatsächlichen Software unberücksichtigt lassen. In diesem Artikel werden die Grundlagen von Testparadigmen beschrieben, welche die Ausführung unmodifizierter Software erlauben und dabei ermöglichen, eine hohe Zuversicht in die getesteten Systeme zu gewinnen. Der Fokus liegt dabei auf der Optimierung von Algorithmen um die redundante Ausführung des Systems zu minimieren, wodurch sich die zum Testen benötigte Zeit um Größenordnungen verringert. http://www.comsys.rwth-aachen.de/fileadmin/papers/2012/2012-soriadustmann-pik-effizient-sde.pdf http://www.degruyter.com/view/j/piko-2012-35-issue-4/pik-2012-0043/pik-2012-0043.xml?format=INT Print Otto Spaniol De Gruyter de 0930-5157 10.1515/pik-2012-0043 OscarSoria Dustmann inproceedings 2012-mass-wirtz-dlsd 2012 10 10 S. fileadmin/papers/2012/2012-mass-wirtz-dlsd.pdf Online IEEE Computer Society

In the absence of such frames, novel techniques are required for rate selection. We present OFRA, a receiver-based rate adaptation algorithm that works with ACK-less traffic. Feedback information is sent on-demand using a control frame to explicitly inform the transmitter about which bit rate to use on subsequent data frames. This approach guarantees standard conformity and exhibits fast and accurate bit rate adaptation at the cost of a modest overhead increase. We evaluate the performance of OFRA against various state-of-the-art rate adaptation schemes by means of simulations. If ACK frames are to be transmitted, OFRA performs better than related work in most considered scenarios, and on par in the others. In the absence of ACKs, OFRA provides large goodput gains under good channel conditions and comparable goodput in other situations.

However, as different codecs perform differently well under certain network conditions like delay, jitter or packet loss, this can lead to a reduction of quality if those conditions change during the call. This paper makes two core contributions: First, we compare the speech quality of a set of stan- dard VoIP codecs given different network conditions. Second, we propose an adaptive end-to-end based codec switching scheme that fully conforms to the SIP standard. Our evaluation with a real-world prototype based on Linphone shows that our codec switching scheme adapts well to changing network conditions, improving overall speech quality. crawler fileadmin/papers/2012/2012-aktas-new2an-codecswitching.pdf Online LNCS Proceedings of the 12th International Conference on Next Generation Wired/Wireless Networking (NEW2AN 2012), St. Pettersburg, Russia.

Using only the accelerometer and the compass readily available in modern smartphones, we accurately localise a user on her route and provide her with turn-by-turn instructions to her destination. To compensate for inaccuracies in step detection and heading estimation, we match the detected steps onto the expected route using sequence alignment algorithms from the field of bioinformatics. As our solution integrates well with OpenStreetMap, it allows painless and cost-efficient collaborative deployment, without the need for additional infrastructure. http://www.tandfonline.com/doi/abs/10.1080/17489725.2012.692620 Online Taylor & Francis

Currently, the execution model is limited to symbolic input for individual nodes, not capturing the important class of timing errors resulting from varying network conditions. In this paper, we introduce symbolic system time in order to systematically find timing-related bugs in distributed systems. Instead of executing time events at a concrete time, we execute them at a set of times and analyse possible event interleavings on demand. We detail on the resulting problem space, discuss possible algorithmic optimisations, and highlight our future research directions. kleenet fileadmin/papers/2012/2012-04-taicpart-soriadustmann-symtime.pdf TAICPART'2012 en 1 OscarSoria Dustmann RaimondasSasnauskas KlausWehrle techreport 2012-draft-garcia-core-security 2012 3 26 draft-garcia-core-security-04 A direct interpretation of the Internet of Things concept refers to the usage of standard Internet protocols to allow for human-to-thing or thing-to-thing communication. Although the security needs are well-recognized, it is still not fully clear how existing IP-based security protocols can be applied to this new setting. This Internet-Draft first provides an overview of security architecture, its deployment model and general security needs in the context of the lifecycle of a thing. Then, it presents challenges and requirements for the successful roll-out of new applications and usage of standard IP-based security protocols when applied to get a functional Internet of Things.
