Böhm, S. and Kirsche, M. Unifying Radio-in-the-Loop Channel Emulation and Network Protocol Simulation to Improve Wireless Sensor Network Evaluation

[Abstract] [BibTeX]

 2018 Communications in Computer and Information Science Vol. 889 Simulation Science, First International Workshop, SimScience 2017, Göttingen, Germany, April 27–28, 2017, pp. 219-238  inproceedings DOI  
Abstract: Evaluations of Internet of Things (IoT) and Wireless Sensor Network (WSN) applications demonstrate the significant and still existing gap between examinations with generic simulation environments and real-life (e.g., field test) or controlled (e.g., testbed) sensor network deployments in terms of realistic and accurate results. The separated use of single examination approaches is often not enough to overcome all evaluation challenges. We therefore propose a combination of discrete-event simulation, radio-channel emulation, and real hardware working together on different layers of the protocol stack of the system-under-test. Our combined approach reduces the gap between abstract simulations and network testbed experiments by providing adjustable radio conditions for repeatable evaluations of WSN and IoT networks.

Böhm, S. and Kirsche, M. Looking into Hardware-in-the-Loop Coupling of OMNeT++ and RoSeNet

[Abstract] [BibTeX]

 2015 Proceedings of the 2nd International OMNeT++ Community Summit (OMNeT 2015)  inproceedings URL PDF 
Abstract: Network emulation using real sensor node hardware is used to increase the accuracy of pure network simulations. Coupling OMNeT++ with network emulation platforms and tools introduces new application possibilities for both sides. This work-in-progress report covers our experiences of using OMNeT++ as a test driver for RoSeNet, a network emulation and test platform for low-power wireless technologies like IEEE 802.15.4. OMNeT++ and RoSeNet were interconnected to enable a co-simulation of real sensor networks with a MAC layer simulation model. Experiences and insights on this Hardware-in-the-Loop (HIL) simulation together with ideas to extend OMNeT++ and to provide a generic interconnection API complete the report.

[Abstract] [BibTeX]

 2015 Proceedings of the 2nd International OMNeT++ Community Summit (OMNeT 2015)  inproceedings URL PDF 
Abstract: We introduce the ongoing integration of Contiki’s uIP stack into the OMNeT++ port of the Network Simulation Cradle (NSC). The NSC utilizes code from real world stack implementations and allows for an accurate simulation and comparison of different TCP/IP stacks and a validation of thereby connected simulation models. uIP(v6) provides resource-constrained devices with an RFC-compliant TCP/IP stack and promotes the use of IPv6 in the vastly growing field of Internet of Things scenarios. This work-in-progress report discusses our motivation to integrate uIP into the NSC, our chosen approach and possible use cases for the simulation of uIP in OMNeT++.

Schuster, D., Grubitzsch, P., Renzel, D., Koren, I., Klauck, R. and Kirsche, M. Global-scale Federated Access to Smart Objects Using XMPP

[Abstract] [BibTeX]

 2014 Proceedings of the IEEE International Conference on Internet of Things (iThings 2014)  inproceedings DOI URL PDF 
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.

Klauck, R. and Kirsche, M. Combining Mobile XMPP Entities and Cloud Services for Collaborative Post-Disaster Management in Hybrid Network Environments

[Abstract] [BibTeX]

 2013 Mobile Networks and Applications - The Journal of SPECIAL ISSUES on Mobility of Systems, Users, Data and Computing Vol. 18 (2) , pp. 253 - 270  article DOI URL PDF 
Abstract: Crises such as the Fukushima incident in Japan showed the demand for flexible and easy-to-use monitoring and communication systems to support post-disaster management (i.e. the organization of actions in the follow-up of disasters), especially when critical infrastructure is affected. 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.

Abstract: This paper introduces a 6LoWPAN simulation model for OMNeT++. Providing a 6LoWPAN model is an important step to advance OMNeT++-based Internet of Things simulations. We integrated Contiki’s 6LoWPAN implementation into OMNeT++ in order to avoid problems of non-standard compliant, non-interoperable, or highly abstracted and thus unreliable simulation models. The paper covers the model’s structure as well as its integration and the generic interaction between OMNeT++ / INET and Contiki.

Klauck, R. and Kirsche, M. Enhanced DNS Message Compression ­ Optimizing mDNS/DNS­SD for the Use in 6LoWPANs

[Abstract] [BibTeX]

 2013 Proceedings of the 9th International Workshop on Sensor Networks and Systems for Pervasive Networks (PerSeNS 2013), co-located with the 11th IEEE International Conference on Pervasive Computing and Communications (PerCom 2013)  inproceedings URL PDF 
Abstract: With the integration of smart objects into the Internet with the help of tiny IP stacks, a direct connection between these objects and ordinary computational devices can be realized at the IP layer. As IP alone cannot ensure an automatic integration at the higher layers, an homogeneous access via services (e.g., discovery, self­configuration) for the Internet of Things vision should be provided for all connected device types. Multicast DNS and DNS Service Discovery are established and widely used standards in current IP­based networks to enable the discovery of devices and services at the application layer with DNS messages. To comply with the current Internet infrastructure, the lightweight implementation uBonjour makes mDNS and DNS­SD available on smart objects. As DNS does not meet the requirements of low data rate smart object networks, we propose to extend DNS with enhanced message compression mechanisms to effectively reduce the number of exchanged IP packets in 6LoWPANs while ensuring backward compatibility.

Klauck, R. and Kirsche, M. Chatty Things - Making the Internet of Things Readily Usable for the Masses with XMPP

[Abstract] [BibTeX]

 2012 Proceedings of the 8th International IEEE Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2012)  inproceedings URL PDF 
Abstract: An important challenge for the Internet of Things is the gap between scientific environments and real life deployments. Smart objects need to be accessible and usable by ordinary users through familiar software and access technologies to facilitate any interaction and to increase their acceptance rate. This work deals with a seamless integration, discovery, and employment of smart objects into the Internet infrastructure under Human-to-Machine (H2M) communication aspects. We introduce an XMPP-based service provisioning sublayer for the IoT to integrate resource constrained devices seamlessly into the Internet by showing how XMPP can empower the collaboration between humans and smart objects. To meet the requirements of constrained devices, we propose to extend XMPP's publish-subscribe capabilities with a topic-based filter mechanism to effectively reduce the number of exchanged XMPP messages. We further present standardized bootstrapping and handling processes for smart objects that adapt automatically to infrastructure and ad hoc network environments and do not require predefined parameters or user interaction. The applicability of XMPP for constrained devices is further demonstrated with an XMPP client and mDNS/DNS-SD service for the Contiki operating system.

Klauck, R. and Kirsche, M. Bonjour Contiki: A Case Study of a DNS-Based Discovery Service for the Internet of Things

Abstract: With the integration of everyday objects and sensors into the Internet, users gain new possibilities to directly interact with their environment. This integration is facilitated by the development of tiny IP stacks that enable a direct Internet connection for resource constrained devices. To provide users with the same level of usability that is predominant in the current Internet infrastructure, a self-configured discovery service for sensors and objects is needed. We thus present a use case of a discovery service based on Multicast DNS and DNS Service Discovery, which we adopt for resource constrained devices and operating systems. Applications using this service can realize direct connections between resource constrained devices following the end-to-end principle of the IP-based Internet, allowing for a seamless integration of potentially millions of objects and sensors into the current Internet and facilitating the pervasive infrastructure that is envisioned by the Internet of Things.

[Abstract] [BibTeX]

 2012 Proceedings of the Work in Progress Session of the 10th IEEE Conference on Pervasive Computing and Communication (PerCom 2012)  inproceedings URL PDF 
Abstract: The Internet of Things vision states that sensors and actuators shall be integrated into the global Internet to facilitate an interaction with and integration of the physical environment. The development of enabling technologies like uIPv6 and 6LoWPAN provide the basic requirements for this interconnection. However, a seamless Internet-connection and interconnection between sensors and actuators can still only be provided with the help of protocols that use gateways, intermediate proxies, and protocol translators. We propose a solution to unify the world of sensors and actuators with the Internet through the use of the Extensible Messaging and Presence Protocol (XMPP) while omitting application protocol gateways and protocol translators at the same time. This article describes our ideas to boost the Internet of Things vision by using XMPP. We present our current work in progress and an outlook into our future working directions in this field.

Abstract: A flexible and easy-to-use disaster management system is essential for providing rescue teams with communication and accurate information. This work promotes a post disaster management system capable of providing communication in infrastructure as well as ad hoc scenarios, and of supporting on demand creation of joint task forces. The system is based on the Extensible Message and Presence Protocol (XMPP). Scenarios, problems, and adequate solution approaches are discussed to enhance post disaster management, specifically in the area of sensor grouping and joint task force cooperation.

 2011 (TR-RI-11-313) Proceedings of the 10th GI/ITG KuVS Fachgespraech Sensornetze (FGSN 2011)  inproceedings URL PDF 
Abstract: Protocols like 6LoWPAN and CoAP allow for an integration of smart objects into an IP-driven Internet of Things, thus enabling new applications such as pervasive health care or intelligent building control automation. Enabling security services (e.g. confidentiality, authentication, authorization) for these applications is essential, as they affect our personal daily life. However, established standard protocols and solutions cannot be directly used in 6LoWPAN/CoAP networks, due to the resource constrained nature of smart objects and new operation challenges in practical deployments. This work presents a compact overview of the current state-of-the-art in the IP-based Internet of Things; details practical security issues that need to be solved, namely end-to-end security and secure multicast based on (D)TLS; and discusses further work.

[Abstract] [BibTeX]

 2011 PIK - Praxis der Informationsverarbeitung und Kommunikation Vol. 34 (1) , pp. 11 - 22  article DOI  
Abstract: Die fortschreitende Entwicklung und Spezialisierung unterschiedlicher Netze verbunden mit einer steigenden Mobilität der Nutzer, führt dazu, dass bisher nur stationär genutzte kollaborative Anwendungen verstärkt in mobilen Umgebungen eingesetzt werden. Die typische Fehleranfälligkeit mobiler Umgebungen erfordert jedoch neue angepasste Mechanismen, um neben einem ubiquitären Zugang zu Kommunikationsnetzen die geforderte Dienstgüte abzusichern. Dieser Beitrag stellt die uBeeMe-Plattform vor, die Anwendungsentwicklungen für ubiquitäre und mobile Szenarien unterstützt. Die Plattform stellt wiederverwendbare Basiskomponenten bereit, die den Anwendungsentwickler beim Lösen immer wiederkehrender Probleme entlasten sollen und es ihm ermöglichen, sich verstärkt auf sein eigentliches Problem zu konzentrieren. Im Beitrag werden das uBeeMe-Projekt, die zugrundeliegenden Anwendungsszenarien, daraus resultierende Anforderungen und die Plattform-Architektur vorgestellt. Darauf aufbauend werden die Hauptkonzepte nahtlose Mobilitätsunterstützung, mobile Gruppenkommunikation, Lokaliserungsunterstützung und sichere Kommunikation detaillierter diskutiert.

Abstract: We introduce Moversight, an early stage group communication protocol, specifically designed for collaborative Peer-to-Peer (P2P) applications in mobile environments. The protocol especially deals with problems encountered in mobile scenarios. It provides basic properties like virtual synchrony of cooperating entities, support for stationary and mobile participants, self-organization and scalability, as well as support for narrow-band communication links without additional central infrastructure.

Klauck, R. and Kirsche, M. Integrating P2PSIP into Collaborative P2P Applications: A Case Study with the P2P Videoconferencing System BRAVIS

[Abstract] [BibTeX]

 2009 Proceedings of the 5th International ICST Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2009)  inproceedings DOI URL PDF 
Abstract: Collaborative applications, such as videoconferencing systems, allow communication partners to interact and communicate anytime and anywhere over the Internet. Today, such applications require central servers for various functions. Even decentralized Peer-to-Peer (P2P) systems still require servers for the invitation and localization of users. The Session Initiation Protocol (SIP) is usually used for videoconferencing systems as a signaling protocol with its registration and proxy servers. This paper introduces a use case where these central SIP servers are replaced in a collaborative application with the help of the decentralized P2PSIP protocol. In the paper, we evaluate different available P2PSIP candidates and describe the integration of a chosen candidate into the P2P videoconferencing system BRAVIS. We present new insights on the practical appliance of P2PSIP for real life collaborative P2P applications along with general remarks for the integration and improvement of P2PSIP.

Kirsche, M. Coexistence and Cooperation for IEEE 802.15.4 powered Wireless Health Care Applications in Scenarios with Dense Radio Conditions

[Abstract] [BibTeX]

 2009 School: Computer Networks and Communication Systems Group, Brandenburg Technical University of Cottbus, Germany  mastersthesis PDF 
Abstract: Forecasts predict a future where health monitoring and health care are available almost everywhere through the omnipresence of network access. The "anywhere and anytime" availability leads to ubiquitous health care scenarios, especially through the use of wireless communication. A consequence of this ubiquity are dense radio conditions, because different wireless technologies are going to coexist on the radio channel. Another important aspect of true ubiquity is the ability for cooperation to enable a flow of information over network and device boundaries. This thesis aims to investigate the aspects and problems of wireless health care solutions in terms of coexistence and cooperation in dense radio conditions, when IEEE 802.15.4 is used as the wireless communication technology. Reference applications and scenarios are abstracted from state-of-the-art inquiries. With the help of simulation models built from the reference scenarios, simulative investigations and problem analyses are conducted. Solutions are proposed for the support of massive coexistence of devices and networks as well as strategies for supporting an Inter- and Intra-Network-Cooperation. The developed concepts are finally evaluated with theoretical and practical proof-of-concept investigations.

Abstract: Videokonferenzen sind ein wichtiges, aber noch wenig genutztes Mittel für kollaborative Applikationen im Internet. Die Peer-to-Peer-Technologie bietet neue Möglichkeiten für die Gestaltung von Videokonferenzsystemen. Im Beitrag werden am Beispiel des BRAVIS-Systems Entwurfsaspekte von P2P-Konferenzsystemen für geschlossene Gruppen diskutiert. Dabei wird neben funktionellen System-Merkmalen auf eine Reihe spezifischer, aus der P2P-Technologie resultierender Probleme wie Vertraulichkeit der Kommunikation, Lokalisierung der Teilnutzer und Firewall/NAT-Traversierung eingegangen.

Kirsche, M. Firewall- und NAT-Traversal für das Videokonferenzsystem BRAVIS

[Abstract] [BibTeX]

 2005 School: Computer Networks and Communication Systems Group, Brandenburg Technical University of Cottbus, Germany  mastersthesis  
Abstract: Diese Arbeit beschäftigt sich mit den Problemen die entstehen, wenn Videokonferenzsoftware in Umgebungen eingesetzt wird, in denen Firewall-Systeme oder Verfahren zur Netzadressenübersetzung (NAT) genutzt werden. Derartige Systeme sind heutzutage weit verbreitet und werden in großen Unternehmensnetzwerken ebenso wie von Privatanwendern genutzt. Um die volle Funktionalität von Videokonferenzsoftware trotz dieser einschränkenden Systeme zu gewährleisten, müssen Methoden zur Anpassung an diese Systeme entwickelt oder Strategien entworfen werden, um mit den Systemen zu interagieren. Die Arbeit befasst sich insbesondere mit der Videokonferenzsoftware "BRAndenburg VIdeo conferencing System" (Bravis), welche am Lehrstuhl Rechnernetze und Kommunikationsysteme der BTU Cottbus entwickelt wurde. Es werden existierende Methoden zur Erkennung und Umgehung von Firewall- und NAT-Systemen für den Einsatz in der Bravis Universitätsversion untersucht und neue Verfahren entwickelt oder vorhandene entsprechend angepasst. Mit Hilfe der Untersuchungen und Analysen wird eine komplette Traveral-Strategie entwickelt. Durch diese Strategie können über Bravis Videokonferenzen trotz einschränkender Firewall- oder NAT-Systeme ermöglicht werden.
