Second, we propose an adaptive end-to-end based codec switching scheme that fully conforms to the SIP standard.

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.}, tags = {mobile_access}, url = {http://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-heer-icc-pisa-sa.pdf}, misc2 = {Print}, publisher = {IEEE Press}, address = {Washington, DC, USA}, booktitle = {International Conference on Computer Communication Networks, ICCCN 2010, Zurich}, event_place = {Zurich, Switzerland}, event_name = {International Conference on Computer Communication Networks, ICCCN 2010}, language = {en}, ISBN = {978-1-4244-7114-0}, DOI = {10.1109/ICCCN.2010.5560103}, reviewed = {1}, author = {Heer, Tobias and Jansen, Thomas and Hummen, Ren{\'e} and Wirtz, Hanno and G{\"o}tz, Stefan and Weingaertner, Elias and Wehrle, Klaus} } @Inbook { 2010-simtools-sasnauskas-transport, title = {Modeling Transport Layer Protocols}, year = {2010}, month = {6}, pages = {389-399}, misc2 = {Print}, editor = {Klaus Wehrle, Mesut Guenes, James Gross}, publisher = {Springer}, address = {Germany}, chapter = {17}, booktitle = {Modeling and Tools for Network Simulation}, language = {en}, ISBN = {978-3-642-12330-6}, reviewed = {1}, author = {Sasnauskas, Raimondas and Weingaertner, Elias} } @Inproceedings { icc2010vpsim, title = {Towards Network Centric Development of Embedded Systems}, year = {2010}, month = {5}, day = {23}, pages = {1-6}, abstract = {Nowadays, the development of embedded system hardware and related system software is mostly carried out using virtual platform environments.

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.}, tags = {mobile_access}, url = {http://www.comsys.rwth-aachen.de/fileadmin/papers/2008/2008-heer-ict-secure-wifi.pdf}, misc2 = {Print}, publisher = {IEEE}, address = {Washington, DC, USA}, booktitle = {Proc. of 15th International Conference on Telecommunication (ICT), St. Petersburg, Russian Federation}, event_place = {St. Petersburg, Russian Federation}, event_name = {15th International Conference on Telecommunication (ICT)}, event_date = {16-19 June 2008}, language = {en}, ISBN = {978-1-4244-2035-3}, reviewed = {1}, author = {Heer, Tobias and G{\"o}tz, Stefan and Weingaertner, Elias and Wehrle, Klaus} } @Inproceedings { 200809WeingaertnerSyncNetworkEmulation, title = {Synchronized Network Emulation}, year = {2008}, month = {6}, day = {3}, volume = {1}, number = {1}, pages = {1-2}, note = {Awarded with ACM SIGMETRICS Best Student Panelist Award.
