We propose a simple local algorithm that is closely related to the over thirty-year-old idea of splay trees and evaluate its adaption performance in the distributed scenario if different communication patterns are provided. To do so, the process of self-adjustment is modeled similarly to a basic network creation game in which the nodes want to communicate with only a certain subset of all nodes. We show that, in general, the game (i.e., the process of local adjustments) does not converge, and that convergence is related to certain structures of the communication interests, which we call conflicts. We classify conflicts and show that for two communication scenarios in which convergence is guaranteed, the self-adjusting tree performs well. Furthermore, we investigate the different classes of conflicts separately and show that, for a certain class of conflicts, the performance of the tree network is asymptotically as good as the performance for converging instances. However, for the other conflict classes, a distributed self-adjusting binary search tree adapts poorly.}}, author = {{Strothmann, Thim Frederik}}, issn = {{1526-1719}}, journal = {{Journal of Graph Algorithms and Applications}}, number = {{1}}, pages = {{79--100}}, publisher = {{Journal of Graph Algorithms and Applications}}, title = {{{The Impact of Communication Patterns on Distributed Self-Adjusting Binary Search Tree}}}, doi = {{10.7155/jgaa.00385}}, volume = {{20}}, year = {{2016}}, } @inproceedings{5812, author = {{Boschmann, Alexander and Agne, Andreas and Witschen, Linus and Thombansen, Georg and Kraus, Florian and Platzner, Marco}}, booktitle = {{2015 International Conference on ReConFigurable Computing and FPGAs (ReConFig)}}, isbn = {{9781467394062}}, publisher = {{IEEE}}, title = {{{FPGA-based acceleration of high density myoelectric signal processing}}}, doi = {{10.1109/reconfig.2015.7393312}}, year = {{2016}}, } @inproceedings{5825, abstract = {{Integrating apps on mobile devices into applications running on other devices is usually difficult. For instance, using a messenger on a smartphone to share a text written on a desktop computer often ends up in a cumbersome solution to transfer the text, because many applications are not designed for such scenarios. In this paper, we present an approach enabling the integration of apps running on Android devices into applications running on other devices and even other platforms. This is achieved by specifying adapters for Android apps, which map their services to a platform-independent service interface. For this purpose, we have developed a domain-specific language to ease the specification of such mappings. Our approach is applicable without the need to modify the existing Android apps providing the service. We analyzed its feasibility by implementing our approach and by specifying mappings for several popular Android apps, e.g., phone book, camera, and file explorer.}}, author = {{Wolters, Dennis and Kirchhoff, Jonas and Gerth, Christian and Engels, Gregor}}, booktitle = {{Service-Oriented Computing}}, editor = {{Sheng, Quan Z. and Stroulia, Eleni and Tata, Samir and Bhiri, Sami }}, isbn = {{9783319462943}}, issn = {{0302-9743}}, keywords = {{Cross-Device, Integration, Android, Adapter, DSL}}, pages = {{171--185}}, publisher = {{Springer International Publishing}}, title = {{{Cross-Device Integration of Android Apps}}}, doi = {{10.1007/978-3-319-46295-0_11}}, year = {{2016}}, } @article{6249, author = {{Fischer, Holger Gerhard and Kauer-Franz, Michaela and Winter, Dominique and Latt, Stefan}}, issn = {{2196-6826}}, journal = {{i-com}}, number = {{1}}, publisher = {{Walter de Gruyter GmbH}}, title = {{{UUX Method Selection}}}, doi = {{10.1515/icom-2016-0011}}, volume = {{15}}, year = {{2016}}, } @inbook{6257, author = {{Fischer, Holger Gerhard and Senft, Björn}}, booktitle = {{Human-Centered and Error-Resilient Systems Development}}, editor = {{Bogdan, Christian}}, isbn = {{9783319449012}}, issn = {{0302-9743}}, location = {{Stockholm, Sweden}}, pages = {{30--41}}, publisher = {{Springer International Publishing}}, title = {{{Human-Centered Software Engineering as a Chance to Ensure Software Quality Within the Digitization of Human Workflows}}}, doi = {{10.1007/978-3-319-44902-9_3}}, volume = {{9856}}, year = {{2016}}, } @inproceedings{6258, author = {{Fischer, Holger Gerhard and Rose, Mirko and Yigitbas, Enes}}, booktitle = {{Joint Proceedings of the REFSQ 2016 Co-Located Events. 2nd Workshop on Continuous Requirements Engineering (CRE)}}, publisher = {{CEUR-WS}}, title = {{{Towards a Task Driven Approach Enabling Continuous User Requirements Engineering}}}, volume = {{1564}}, year = {{2016}}, } @proceedings{6307, editor = {{Hess, Steffen and Fischer, Holger Gerhard}}, publisher = {{Gesellschaft für Informatik e.V. und German UPA e.V.}}, title = {{{Mensch und Computer 2016 - Usability Professionals.

This becomes even more challenging when agile development methodologies, like DevOps, are applied. In such scenarios, management and orchestration systems are continuously facing new versions of functions and services which makes it hard to decide how much resources have to be allocated to them to provide the expected service performance. One solution for this problem is to support resource allocation decisions with performance behavior information obtained by profiling techniques applied to such network functions and services. In this position paper, we analyze and discuss the components needed to generate such performance behavior information within the NFV DevOps workflow. We also outline research questions that identify open issues and missing pieces for a fully integrated NFV profiling solution. Further, we introduce a novel profiling mechanism that is able to profile virtualized network functions and entire network service chains under different resource constraints before they are deployed on production infrastructure.}}, author = {{Peuster, Manuel and Karl, Holger}}, booktitle = {{Fifth European Workshop on Software-Defined Networks, EWSDN 2016, Den Haag, The Netherlands, October 10-11, 2016}}, location = {{Den Haag}}, pages = {{7----12}}, title = {{{Understand Your Chains: Towards Performance Profile-Based Network Service Management}}}, doi = {{10.1109/EWSDN.2016.9}}, year = {{2016}}, } @inproceedings{731, abstract = {{Traditional cellular networks are forced to remain active regardless of the actual amount of traffic that is currently produced/requested, with a clear waste of energy.

In this demonstration, we showcase a testbed that uses Wi-Fi access points to emulate small cells of the data layer and a publicly available cellular connection as the signalling layer. We use off-the-shelf Android smartphones with an ad-hoc networking management module and a MultiPath TCP-enabled kernel to manage the Wi-Fi and cellular interfaces simultaneously.

This is often done by starting new VNF instances or stopping old ones. A problem of these scale operations is that most network functions are stateful and their internal state is not automatically migrated when traffic is redistributed in the deployment. As a result, mechanisms are needed to exchange or migrate internal network function state between VNF instances. This paper presents a state management framework that creates a logically distributed state store on top of elastically deployed virtual network functions. We also introduce a novel programming model that provides both a local and a global view of the state to each VNF instance. We discuss the integration of our framework into existing network function virtualization architectures and compare the performance of our prototype to a centralized and a distributed state store solution.}}, author = {{Peuster, Manuel and Karl, Holger}}, booktitle = {{IEEE NetSoft Conference and Workshops, NetSoft 2016, Seoul, South Korea, June 6-10, 2016}}, location = {{Seoul}}, pages = {{6----10}}, title = {{{E-State: Distributed state management in elastic network function deployments}}}, doi = {{10.1109/NETSOFT.2016.7502432}}, year = {{2016}}, } @inproceedings{735, author = {{Auroux, Sébastien and Parruca, Donald and Karl, Holger}}, booktitle = {{27th IEEE Annual International Symposium on Personal, Indoor, and Mobile Radio Communications, {PIMRC} 2016, Valencia, Spain, September 4-8, 2016}}, pages = {{1----6}}, title = {{{Joint real-time scheduling and interference coordination for wireless factory automation}}}, doi = {{10.1109/PIMRC.2016.7794927}}, year = {{2016}}, }
