Such systems can effectively only be realized with a merging of various device classes and the integration of mobile actors and wireless communication technologies to provide the necessary flexibility. This article introduces a system design that combines portable hand-held devices as well as autonomous sensors through XMPP with the flexibility of cloud services to support post-disaster management. This combination provides the communication between the different involved parties (e.g., rescue teams, relief forces, NGOs) and enables a global view on sensed data through the use of cloud-based storage and analysis services. Along with a discussion about requirements and a description of appropriate solutions and initial evaluations, we present new insights on the practical appliance of XMPP and potential enhancements for XMPP-based real life collaboration applications in hybrid (ad hoc and infrastructure) networkscenarios.We also show that resource constrained devices can run the XMPP protocol to extend smartphones with sensors or to connect different device classes in a seamless way.}, language = {en} } @inproceedings{KlauckLorenzHentschel, author = {Klauck, Ronny and Lorenz, Sebastian and Hentschel, Christian}, title = {Collaborative Work in VR Systems: A Software-Independent Exchange of Avatar Data}, series = {IEEE 6th International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 5-7 Sept. 2016}, booktitle = {IEEE 6th International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 5-7 Sept. 2016}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-5090-2096-6}, doi = {10.1109/ICCE-Berlin.2016.7684738}, pages = {4}, language = {en} } @inproceedings{SchusterGrubitzschRenzeletal., author = {Schuster, Daniel and Grubitzsch, Philipp and Renzel, Dominik and Klauck, Ronny and Kirsche, Michael}, title = {Global-scale Federated Access to Smart Objects Using XMPP}, series = {2014 IEEE International Conference on Internet of Things (iThings 2014), and IEEE green computing and communications (GreenCom 2014) and IEEE cyber, physical and social computing (CPSCom 2014), Taipei, Taiwan, 1 - 3 September 2014}, booktitle = {2014 IEEE International Conference on Internet of Things (iThings 2014), and IEEE green computing and communications (GreenCom 2014) and IEEE cyber, physical and social computing (CPSCom 2014), Taipei, Taiwan, 1 - 3 September 2014}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-4799-5967-9}, pages = {185 -- 192}, abstract = {Communication with smart objects currently only works in isolated, sometimes even proprietary islands. This lack of interoperability limits the value of smart objects connected to the Internet of Things (IoT). We propose to use the eXtensible Messaging and Presence Protocol (XMPP) to connect IoT islands. XMPP is inherently federated, secure, globally scalable and designed for collaboration. We use XMPP Multi-User Chat (MUC) to build a secure and accessible platform for sensor data exchange between organizations. We demonstrate a scenario of three distributed and interconnected XMPP-driven sites, whereas different client types access sensor data from all sites. Our evaluation results confirm that the architectural pattern presented in this work can easily be used in any XMPP-based system without the need to enhance or to extend the standards.}, language = {en} } @inproceedings{MehnerKlauckKoenig, author = {Mehner, Stefan and Klauck, Ronny and K{\"o}nig, Hartmut}, title = {Location-independent fall detection with smartphone}, series = {The 6th International Conference on PErvasive Technologies Related to Assistive Environments, PETRA '13, Island of Rhodes, Greece, May 29-31, 2013}, booktitle = {The 6th International Conference on PErvasive Technologies Related to Assistive Environments, PETRA '13, Island of Rhodes, Greece, May 29-31, 2013}, editor = {Makedon, Fillia and Betke, Margrit and Seif El-Nasr, Magy and Maglogiannis, Ilias}, publisher = {ACM}, address = {New York, NY}, isbn = {978-1-4503-1973-7}, doi = {10.1145/2504335.2504346}, pages = {8}, abstract = {Due to demographic changes in developed industrial countries and a better medical care system, the number of elderly people who still live in their home environment is rapidly growing because there they feel more comfortable and independent as in a clinical environment or in a residential care home. The elderly often live alone and receive only irregular visits. Due to impaired physical skills the probability of falls significantly increases. The detection of falls is a crucial aspect in the care of elderly. Falls are often detected very late with severe consequential damages. There are existing approaches for automatic fall detection. They usually deploy special external devices. Elderly people often do not accept these devices because they expose their frailty. In this paper, we present a location-independent fall detection method implemented as a smartphone application for an inconspicuous use in nearly every situation of the daily life. The difficulty of our approach is in the low resolution range of integrated acceleration sensors and the limited energy supply of the smartphone. As solution, we apply a modular threshold-based algorithm which uses the acceleration sensor with moderate energy consumption. Its fall detection rate is in the average of current relevant research.}, language = {en} } @inproceedings{GaeblerKlauckPinketal., author = {G{\"a}bler, Jan and Klauck, Ronny and Pink, Mario and K{\"o}nig, Hartmut}, title = {uBeeMe - a Platform to Enable Mobile Collaborative Applications}, series = {Proceedings of the 9th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2013), Austin, Texas, USA, October, 2013}, booktitle = {Proceedings of the 9th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2013), Austin, Texas, USA, October, 2013}, publisher = {IEEE}, address = {Piscataway, NJ}, pages = {188 -- 196}, language = {en} } @inproceedings{KlauckKirsche, author = {Klauck, Ronny and Kirsche, Michael}, title = {Enhanced DNS Message Compression - Optimizing mDNS/DNS-SD for the Use in 6LoWPANs}, series = {Proceedings,9th IEEE International Workshop on Sensor Networks and Systems for Pervasive Computing 2013 (PerSeNS 2013), co-located with the 11th IEEE Conference on Pervasive Computing and Communication (PerCom 2013), San Diego, Calif., USA, 2013}, booktitle = {Proceedings,9th IEEE International Workshop on Sensor Networks and Systems for Pervasive Computing 2013 (PerSeNS 2013), co-located with the 11th IEEE Conference on Pervasive Computing and Communication (PerCom 2013), San Diego, Calif., USA, 2013}, publisher = {IEEE}, isbn = {978-1-4673-5075-4}, doi = {10.1109/PerComW.2013.6529565}, pages = {596 -- 601}, language = {en} } @inproceedings{KirscheKlauck, author = {Kirsche, Michael and Klauck, Ronny}, title = {Unify to Bridge Gaps: Bringing XMPP into the Internet of Things}, series = {2012 IEEE International Conference on Pervasive Computing and Communications (PerCom 2012), Lugano, Switzerland, 19 - 23 March 2012}, booktitle = {2012 IEEE International Conference on Pervasive Computing and Communications (PerCom 2012), Lugano, Switzerland, 19 - 23 March 2012}, publisher = {Institute of Electrical and Electronics Engineers (IEEE )}, address = {Piscataway, NJ}, isbn = {978-1-467-30256-2}, pages = {455 -- 458}, language = {en} } @inproceedings{KlauckKirsche, author = {Klauck, Ronny and Kirsche, Michael}, title = {Integrating P2PSIP into Collaborative P2P Applications: A Case Study with the P2P Videoconferencing System BRAVIS}, series = {Proceedings of the 5th International ICST Conference on Collaborative Computing: Networking, Applications and Worksharing, CollaborateCom, 11 - 14 November 2009, Crystal City, Washington D.C., USA}, booktitle = {Proceedings of the 5th International ICST Conference on Collaborative Computing: Networking, Applications and Worksharing, CollaborateCom, 11 - 14 November 2009, Crystal City, Washington D.C., USA}, isbn = {978-963-979976-9}, language = {en} } @book{Klauck, author = {Klauck, Ronny}, title = {Integration von P2PSIP in eine kollaborative Anwendung: Am Beispiel des P2P-Videokonferenzsystems BRAVIS}, publisher = {Saarbr{\"u}cken : VDM Verl.
