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.

However, it is currently not possible to investigate BitTorrent with ns-3 due to the unavailability of an according application model. In this paper we eliminate this burden. We present a highly modular BitTorrent model which allows for the easy simulation of different BitTorrent systems such as file sharing as well as present and future BitTorrent-based Video-on-Demand systems.

For municipalities, it is often challenging to achieve the bandwidth and coverage that is necessary for many of the envisioned network services. At the same time, Wi-Fi-sharing communities achieve high bandwidth and good coverage at a very low cost by capitalizing on the dense deployment of private access points in urban areas. However, from a technical, conceptual, and security perspective, Wi-Fi sharing community networks resemble a patchwork of heterogeneous networks instead of one well-planned city-wide network. This patchwork character stands in stark contrast to a uniform, secure platform for public and commercial services desirable for the economic success of such a network. Hence, despite its cost-efficiency, the community-based approach cannot be adopted by municipalities easily. In this paper, we show how to realize municipal wireless services on top of a Wi-Fi-sharing infrastructure in a technically sound and economically attractive fashion. In particular, we focus on how to securely provide services to mobile clients with and without client-side software support. Our solution cleanly separates the roles of controlling and administering the network from providing bandwidth and wireless access. With this separation, commercial ISPs and citizens with their private Wi-Fi can contribute to the network infrastructure. This allows municipalities in turn to focus their resources on municipal wireless services. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-heer-icc-pisa-sa.pdf Print IEEE Press

The high level of modeling detail (hardware elements are partially modeled in a cycle-accurate fashion) is required for many core design tasks. At the same time, the high computational complexity of virtual platforms caused by the detailed level of simulation hinders their application for modeling large networks of embedded systems. In this paper, we propose the integration of virtual platforms with network simulations, combining the accuracy of virtual platforms with the versatility and scalability of network simulation tools. Forming such a hybrid toolchain facilitates the detailed analysis of embedded network systems and related important design aspects, such as resource effectiveness, prior to their actual deployment. https://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-schuermans-weingaertner-network_centric.pdf Online IEEE Proceedings of the IEEE International Conference on Communications (ICC), Cape Town, South Africa, May 23-27 en 978-1-4244-6402-9 1550-3607 10.1109/ICC.2010.5502185 1 StefanSchürmanns EliasWeingaertner TorstenKempf GerdAscheid KlausWehrle RainerLeupers article 200803WeingaertnerPromox Electronic Communications of the EASST 2009 3 17 2009 1-10 In this paper, we present a preliminary glance on our framework for protocol stack monitoring using Xen (ProMoX). ProMoX uses the Xen hypervisor to virtualize entire instances of operating systems which may execute any arbitrary protocol implementation. By utilizing system virtualization for external monitoring, ProMoX can transparently inspect any protocol state and performance metrics of protocol implementations carried by a guest operating system. This way, ProMoX supports both the indentification of faults within early prototypes as well as the evaluation of new protocol designs. Accepted for publication online EASST

While ns-2 has established itself as virtually the standard network simulation tool, other network simulators have gained more and more attention during the last years. In this paper, we briefly survey new developments in the field of network simulation and conduct a performance comparison study by implementing an identical simulation set-up in five simulators, namely ns-2, OMNet++, ns-3, SimPy and JiST/SWANS. Our results reveal large differences according to both run-time performance and memory usage. http://www.comsys.rwth-aachen.de/fileadmin/papers/2009/2009-weingaertner-simulator_comparison.pdf Print IEEE Proceedings of the IEEE International Conference on Communications 2009 (ICC 2009) Dresden, Germany en 1 EliasWeingaertner Hendrikvom Lehn KlausWehrle conference 2008-heer-pisa-full 2008 6 16 1 1-7 The proliferation of broadband Internet connections has lead to an almost pervasive coverage of densely populated areas with private wireless access points. To leverage this coverage, sharing of access points as Internet uplinks among users has first become popular in communities of individuals and has recently been adopted as a business model by several companies. However, existing implementations and proposals suffer from the security risks of directly providing Internet access to strangers. In this paper, we present the P2P Wi-Fi Internet Sharing Architecture PISA, which eliminates these risks by introducing secure tunneling, cryptographic identities, and certificates as primary security concepts. Thus, PISA offers nomadic users the same security that they expect from a wired Internet connection at home. Based on its three fundamental mechanisms, PISA achieves a flexibility which opens significant advantages over existing systems. They include user mobility, anonymity, service levels with different performance and availability characteristics, and different revenue models for operators. With this combination of key features, PISA forms an essential basis for global, seamless, and secure Wi-Fi sharing for large communities. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2008/2008-heer-ict-secure-wifi.pdf Print IEEE

Until now, the simulation in charge of representing the network has been required to be real-time capable, as otherwise a time drift between the simulation and the real network devices may occur and corrupt the results. In this paper, we present our work on synchronized network emulation. By adding a central synchronization entity and by virtualizing real systems for means of control, we can build-up network emulations which contain both unmodified x86 systems and network simulations of any complexity. This is a revised version of a paper originally presented at the ACM HotMetrics 2008 workshop. print en 0163-5999 10.1145/1453175.1453185 1 EliasWeingaertner FlorianSchmidt TobiasHeer KlausWehrle techreport 200807VOMLEHNAIB200816NetworkSimulatorComparison Aachener Informatik Berichte 2008 2008-16 AIB 2008-16 1-28 Ranging from the development of new protocols to validating analytical performance metrics, network simulation is the most prevalent methodology in the field of computer network research.

In this paper, we first survey recent contributions in the field of network simulation tools as well as related aspects such as parallel network simulation. Moreover, we present preliminary results which compare the resource demands for ns-3, JiST, SimPy and OMNeT++ by implementing the identical simulation scenario in all these network simulation tools. https://www.comsys.rwth-aachen.de/fileadmin/papers/2008/AIB-2008-16.pdf Online

Within the talk, we present our work on the novel paradigm of Hybrid Sensor-Vehicular Networks (HSVNs) and their contribution to next-generation network architectures. The idea behind Hybrid Sensor-Vehicular Networks is to deploy sensor nodes within the road environment. For example, it is imaginable that future roads will be equipped with sensor nodes that are able to sense environmental events, such as ice, aquaplaning or structural damages. Those events are gathered locally using a wireless sensor network and are delivered directly to vehicles that pass by. Afterwards, information is spread in a wider area using the VANET. https://www.comsys.rwth-aachen.de/fileadmin/papers/2007/2007-eurongi-hybrid-wsn-weingaertner-kargl.pdf http://www3.informatik.uni-wuerzburg.de/euroview/2007/program.shtml online EuroNGI online Proceedings of 7th Würzburg Workshop on IP "Visions of Future Generation Networks" (EuroView2007) Würzburg, Germany 7th Würzburg Workshop on IP "Visions of Future Generation Networks" (EuroView2007) 23.7.2007 / 24.7.2007 en none none 1 EliasWeingaertner FrankKargl mastersthesis 200705WeingaertnerDiplomarbeit 2007 In this thesis, an approach for the integration of wireless sensor networks with vehicular ad-hoc networks for the purpose of road and traffic monitoring is investigated.

We further investigate the feasibility of the approach using a real-world deployment. German
