B. Sliwa, N. Piatkowski, C. Wietfeld, LIMITS: Lightweight machine learning for IoT systems with resource limitations, In 2020 IEEE International Conference on Communications (ICC), Dublin, Ireland, June 2020.

Abstract - Exploiting big data knowledge on small devices will pave the way for building truly cognitive Internet of Things (IoT) systems. Although machine learning has led to great advancements for IoT-based data analytics, there remains a huge methodological gap for the deployment phase of trained machine learning models. For given resource-constrained platforms such as Microcontroller Units (MCUs), model choice and parametrization are typically performed based on heuristics or analytical models. However, these approaches are only able to provide rough estimates of the required system resources as they do not consider the interplay of hardware, compiler specific optimizations, and code dependencies. In this paper, we present the novel open source framework LIghtweight Machine learning for IoT Systems (LIMITS), which applies a platform-in-the-loop approach explicitly considering the actual compilation toolchain of the target IoT platform. LIMITS focuses on high level tasks such as experiment automation, platform-specific code generation, and sweet spot determination. The solid foundations of validated low-level model implementations are provided by the coupled well-established data analysis framework Waikato Environment for Knowledge Analysis (WEKA). We apply and validate LIMITS in two case studies focusing on cellular data rate prediction and radio-based vehicle classification, where we compare different learning models and real world IoT platforms with memory constraints from 16 kB to 4 MB and demonstrate its potential to catalyze the development of machine learning enabled IoT systems.




F. Kurtz, I. Laukhin, C. Bektas, C. Wietfeld, Evaluating Software-Defined Networking-Driven Edge Clouds for 5G Critical Communications, In 9th International Conference on ICT Convergence (ICTC), IEEE, Jeju-si, Republic of Korea, October 2018.

Abstract - Modern societies are increasingly dependent on Critical Infrastructures (CIs) such as Smart Grids (SGs) and Intelligent Transportation Systems (ITS). Due to continuously rising demands in terms of efficiency and capabilities, complex control and monitoring strategies are employed. These in turn rely on robust, high performance communication networks. As CIs are distributed systems with diverging demands, the deployment of individual networks is often too costly and time consuming. Furthermore, the vast physical scope traditionally results in unacceptably high end-to-end delays. Therefore, a convergence of public and dedicated networks, as well as traditional Information and Communication Technology (ICT) with Information Technology (IT), are considered key aspects of 5G for addressing these challenges. Hence, this paper provides an empirical evaluation of CI communication services on basis of a Software-Defined Networking (SDN) and Network Function Virtualization (NFV) driven Edge Clouds (ECs) within a sliced 5G network. By shifting computing resources from the backbone or back office towards the network’s access level, ECs allow for drastically reduced delays. Also, the traffic load on several layers of the communication infrastructure is reduced, as data can be kept locally, i.e. close to the source. This is demonstrated by shifting an ITS application from a central cloud to the EC. Services are transferred step-wise and transparently, minimizing interruptions while dynamically adapting to the backhaul’s available data rate. The developed system is evaluated under realistic traffic conditions within a physical testing environment.




B. Sliwa, T. Liebig, R. Falkenberg, J. Pillmann, C. Wietfeld, Efficient Machine-type Communication using Multi-metric Context-awareness for Cars used as Mobile Sensors in Upcoming 5G Networks, In IEEE Vehicular Technology Conference (VTC-Spring), Porto, Portugal, June 2018.

Abstract - Upcoming 5G-based communication networks will be confronted with huge increases in the amount of transmitted sensor data related to massive deployments of static and mobile Internet of Things (IoT) systems. Cars acting as mobile sensors will become important data sources for cloud-based applications like predictive maintenance and dynamic traffic forecast. Due to the limitation of available communication resources, it is expected that the grows in Machine-Type Communication (MTC) will cause severe interference with Human-to-human (H2H) communication. Consequently, more efficient transmission methods are highly required. In this paper, we present a probabilistic scheme for efficient transmission of vehicular sensor data which leverages favorable channel conditions and avoids transmissions when they are expected to be highly resource-consuming. Multiple variants of the proposed scheme are evaluated in comprehensive real-world experiments. Through machine learning based combination of multiple context metrics, the proposed scheme is able to achieve up to 164% higher average data rate values for sensor applications with soft deadline requirements compared to regular periodic transmission.

N. Dorsch, F. Kurtz, C. Wietfeld, Communications in Distributed Smart Grid Control: Software-Defined vs. Legacy Networks, In IEEE Conference on Energy Internet and Energy System Integration, Beijing, China, November 2017. 

Abstract - To deal with the challenges of increasingly fluctuating power flows in future energy systems, distributed control using a Multi-Agent System (MAS) is considered a promising solution. However, these agents require appropriate Information and Communication Technology (ICT) infrastructures to coordinate their actions. Software-Defined Networking (SDN) is a novel approach for dynamic and flexible configuration of communication networks, which enables integration of reliability and security enhancing measures, while optimizing network load and cost efficiency. In this work, the concept of SDN and traditional networking are compared regarding their applicability for establishing distributed power grid control. In particular, we discuss the aspects of security, reliability, transmission paradigms, topology detection and configuration effort. Using a typical transmission grid scenario, derived from the well-established New England Test System (NETS), we demonstrate the capabilities of SDN to improve significantly on the reliability of MAS communications, while incurring minimal administration overhead. Overall, our study indicates clear benefits of applying SDN for distributed power grid control.




S. Gröning, J. Schmutzler, C. Wietfeld, Conformance Testing of Electric Vehicle Charging Communication based on TTCN-3, Best Presentation Award (selected by audience) at UCAAT User Conference on Advanced Automated Testing, ETSI, Berlin, Germany, October 2017. 

Abstract - Electric Vehicles (EVs) are a key component for green transportation and future smart grids. At the same time, they define a new, scalable but heterogeneous global market. Hence, interoperability of charging communication is a core enabler for user acceptance and economics of scale. However, its complexity increases by the number of use cases, e.g. for association, authentication and accounting used for Plug and Charge (PnC), demand management or bidirectional power flow. Thus, a considerable amount of testing is required in order to enable interoperability between independent implementations. EV charging communication brings together cross-domain vendors from the automotive-, utility- and communication domain. However, only a standardized approach based on a publicly available and formally defined testing language like TTCN-3 holds true for the required testing scope of the charging communication interface and a systematic approach for corresponding automated test procedures. The presentation gives an overview of requirement-based conformance testing of the Combined Charging System (CCS) using TTCN-3 and describes furthermore lessons learned using TTCN-3 as a formal test case description in a multi-domain standardization process and how automated testing based on TTCN-3 can improve interoperability of electric vehicle charging communication.



J. Tiemann, C. Wietfeld, Scalable and Precise Multi-UAV Indoor Navigation using TDOA-based UWB Localization, In 2017 International Conference on Indoor Positioning and Indoor Navigation (IPIN), Sapporo, Japan, September 2017.

Abstract - Ultra-wideband wireless positioning technologies based on IEEE 802.15.4a have gained attention for various use cases requiring highly precise localization. Multi-rotor unmanned aerial vehicle (UAV) systems provide several sensors for stabilization and navigation. However, absolute indoor positioning poses a problem for autonomous robotic systems. The specific challenge addressed in this paper is enabling novel applications with autonomous UAV systems through tight integration with scalable and precise receiver-side time-difference of arrival (TDOA) based ultra-wideband (UWB) indoor localization. For the in-depth validation of the proposed approach, several experiments are performed. One proves the repeatability of the proposed method by following a predefined trajectory ten times achieving close to optical motion-capture based control performance, with a 3rd quartile of the alignment error lower than 10 cm. Another experiment addresses the simultaneous flight of three UAVs in close proximity and delivers an analysis of the real-time capabilities which in turn proves the multi-user scalability. The last experiment demonstrates a user-interactive application of the proposed approach in a logistics environment. A video along with the raw samples, reference data and processed positions of the aforementioned experiments is provided alongside this work.

, "LIMoSim: A lightweight and integrated approach for simulating vehicular mobility with OMNeT++", In OMNeT++ Community Summit 2017, Bremen, Germany, September 2017

Abstract -Reliable and efficient communication is one of the key requirements for the deployment of self-driving cars. Consequently, researchers and developers require efficient and precise tools for the parallel development of vehicular mobility and communication. Although current state-of-the-art approaches allow the coupled simulation of those two components, they are making use of multiple specialized simulators that are synchronized using interprocess communication, resulting in highly complex simulation setups. Furthermore, the compatibility of those simulators requires constant attention as they are developed independently. In this paper, we present a lightweight and integrated approach for simulating vehicular mobility directly in Objective Modular Network Testbed in C++ (OMNeT++) and INET without the need for external tools or Interprocess Communication (IPC). The proposed framework Lightweight ICT-centric Mobility Simulation (LIMoSim) is available as Open Source software and can easily be combined with other third-party extension frameworks for providing vehicular mobility based on well-known microscopical models. In contrast to existing approaches, the amount of necessary preprocessing steps for simulation setups is significantly reduced. The capabilities of LIMoSim are demonstrated by a proof of concept evaluation in combination with the Long Term Evolution (LTE) simulation framework SimuLTE.


J. Tiemann, F. Eckermann and C. Wietfeld, "ATLAS - an open-source TDOA-based Ultra-wideband localization system," 2016 International Conference on Indoor Positioning and Indoor Navigation (IPIN), Alcala de Henares, 2016, pp. 1-6.

Abstract - IEEE 802.15.4a Ultra-wideband based wireless positioning has recently gained attention for precise localization. However, the multi-user scalability of those, mostly two-way ranging based, approaches is not considered. Due to the exchange of multiple frames per ranging, two-way ranging has significant downsides in terms of scalability. This paper proposes and validates a novel approach for a multi-user time-difference of arrival based localization system using wireless clock synchronization. The system accuracy is assessed using a complex experiment, covering robotic movement and an optical reference system for comparable results. It is shown, that the accuracies achievable by time-difference of arrival positioning with wireless clock synchronization are comparable to similar two-way ranging based approaches. All raw samples, reference data and processed positions are provided alongside this work.


SCVT Award 2013

B. Niehoefer, F. Schweikowski and C. Wietfeld, Smart Constellation Selection for Precise Vehicle Positioning in Urban Canyons using a Software-Defined Receiver Solution, 20th IEEE Symposium on Communications and Vehicular Technologies (SCVT),  Nov. 2013.

Abstract — Positioning techniques based on satellite navigation systems are nowadays standard in most commercial vehicles. But standalone receivers are effected by multipath and atmospheric effects and hence their performance may be decreased, especially in challenging environments that directly affects the usage of satellite-based positioning in traffic-relevant and by that safety-critical systems. Therefore, this paper describes, based on an exemplary implementation of an Advanced Software-Defined radio receiver (ASDR) for Global Navigation Satellite Systems, the impact of the direct receiver surrounding as well as a so-called Smart Constellation Selection (SCS) as pre-positioning routine to increase the accuracy by just using already available data at the receiver side. Beneath the implementation of the receiver itself, the functionality and performance of the SCS will be explained. In addition, this contribution contains the introduction of a freely available database with geo-referenced GPS measurements including web-based analysis functionalities to enable other researches to test and evaluate their ideas for future GNSS enhancements.


H. Georg, S. C. Müller, C. Rehtanz and C. Wietfeld, "A HLA Based Simulator Architecture for Co-simulating ICT Based Power System Control and Protection Systems", 3rd IEEE International Conference on Smart Grid Communications (SmartGridComm 2012), Tainan City, Taiwan, Nov 2012.

Abstract — Power systems and especially Smart Grids increasingly apply Information and Communication Technologies (ICT) for exchanging information over wide area networks. Here, the performance of the ICT has become crucial for the development of new Wide Area Monitoring, Protection And Control (WAMPAC) systems. In this context, simulations are a common way for evaluation, but power systems and communication networks are usually analysed with dedicated simulators. Therefore a combined simulation for analysing the dynamics and mutual impacts of both domains is needed. In this paper we present a generic hybrid simulation architecture based on the IEEE standard 1516 - High Level Architecture to enable a combined simulation of power systems and communication networks in an integrated simulation environment. First, we introduce our hybrid simulator architecture, along with the communication and synchronization process between sub-simulators. Secondly, we present our communication networks architecture for modelling the network traffic caused by the information transmitted by control and protection algorithms within the electrical transmission system. Finally, we introduce our modelling approach for mapping entities between the power systems and the communication networks. For this purpose, we introduce our concept of a Substation Data Processing Unit, which represents entities on substation level by providing an IEC 61850 based model for mapping logical functions for local process control, implementing decentralized protection and control algorithms and providing additional components for the power systems (e.g Phasor Measurement Units (PMUs)).


Subik, S. and Wietfeld, C., "Integrated PMR-Broadband-IP Network for Secure Realtime Multimedia Information Sharing",IEEE International Conference on Technologies for Homeland Security, Waltham, MA, USA, IEEE, Nov 2011.

In this paper, the authors present a novel solution for the integration of TETRA-based PMR and IP based wireless broadband networks through a novel inter-system interface. This solution enables secure group communications based on PMR standards using heterogeneous devices ranging from a traditional PMR device to smart phones such as the iPhone. Thereby a SmartPhone user will be enabled to leverage on one hand the multimedia data capabilities of 3G und 4G wireless networks (UMTS, LTE) while at the same time be part of a PMR group communication. In other words, any authorized Smart Phone can become part of a PMR communication group by simply downloading the appropriate, dedicated Application. As a key benefit, homeland security personnel can be included in the disaster response actions instantaneously, without necessarily carrying around a dedicated PMR device and without the need for PMR coverage. In contrast to existing solutions, the proposed interface solution prevents the reduction of the voice quality when bridging system boundaries by tandem encoding with a TETRA-over-IP (ToIP) interconnection. The presented solutions include different interconnection setups including Trunked Mode (TMO) and Direct Mode (DMO) capabilities. To enable the group communications services as known in PMR systems, a dedicated protocol, the Push-to-X protocol developed by CNI, is leveraged. The results of performance evaluations show that the speech quality is still acceptable even under harsh conditions. The proposed system therefore paves the way towards a future, high performance PMR based on LTE, while preserving backwards compatibility with existing PMR systems.


Daniel, K., Rohde, S. and Wietfeld, C., "Leveraging Public Wireless Communication Infrastructures for UAV-Based Sensor Networks",IEEE International Conference on Technologies for Homeland Security, Waltham, MA, USA, IEEE, Nov 2010.

Unmanned Aerial Vehicles (UAV) enable the in-depth reconnaissance and surveillance of major incidents. Uncontrolled emissions of liquid or gaseous contaminants in cases of volcanic eruptions, large fires, industrial incidents or terrorist attacks can be analyzed by utilizing UAVs. Hence, the use of cognitive Unmanned Aerial Systems (UAS) for distributing mobile sensors in incident areas is in general a significant value add for remote sensing, reconnaissance, surveillance and communication purposes. Police departments, fire brigades and other homeland security organizations will have access to medium and small size UAVs in the near future and will integrate UAVs in their work flow. In this paper we are focusing on the civilian concepts of operations (CONOPS) for UAVs, in particular for small-scale UAVs. We present viable concepts on system level for leveraging public wireless communication networks for UAV-based sensor networks with respect to existing constraints and user requirements.


Lewandowski, A., Koester, V. and Wietfeld, C. , "Performance Evaluation of AODV- and OLSR-meshed IP-enabled IEEE802.15.4", The Third International Conference on Advances in Mesh Networks (Mesh 2010), Venice/Mestre, Italy, IARIA/IEEE (awarded with the Best Paper Award), July 2010.

Safety critical applications of IEEE 802.15.4 networks require autonomous network reconfiguration and dynamic meshing in case of node failures or changing environmental influences. In contrast to the classical approach of wireless sensor networks, this paper focuses on the development of enhanced network services like multimedia transmissions in a gas concentration monitoring scenario. Thus, using IEEE 802.15.4 reduces the energy consumption in comparison to Wi-Fi networks. Therefore, this paper demonstrates the application of Ad-hoc On Demand Distance Vector (AODV) and Optimized Link State Routing (OLSR) on IEEE 802.15.4 nodes based on an IP layer - instead of relying on the standard ZigBee configuration. The new network configuration is evaluated for handover processes between mobile and stationary nodes. The time delay, maximum throughput and generated overhead is compared between the two routing protocols for different node constellations. Finally, the lifetime of the node is evaluated in comparison to the ordinary IEEE 802.15.4 configuration and IEEE 802.11. Concluding, the application of AODV and OLSR for power-constrained IEEE 802.15.4 nodes is proposed.


Tran, T. and Wietfeld, C., "Approaches for Optimizing the Performance of a Mobile SAML-based Emergency Response System",The 13th IEEE Enterprise Distributed Object Computing Conference Workshops (EDOC), Auckland, New Zealand, IEEE, Vol. 1, pages: 148-156, Sept 2009, Best Paper Award in MTECS.

The fast access of essential and latest information from anytime and anywhere is crucial for the success of fire mission planning and is still a challenge, if requirements such as high performance, security and simplicity have to be met concurrently. However, the secure access to the distributed information of public authorities like building plans or medical patient data is currently mostly available via the traditional time-consuming post. Due to this problem a mobile integrated solution is developed, which allows a secure and holistic access to relevant information. The solution is based on the Security Assertion Markup Language (SAML) architecture which specifies an XML based standard for exchanging authentication and authorization data. Unfortunately, the performance of this approach is not applicable for time-critical mobile applications because of the SAML specific communication procedures. Thus, this paper presents two approaches for boosting the performance and shows the results of performance evaluation for the required validation. Moreover, an analytic model is introduced for identifying the SAML specific processing time.


Niehoefer, B., Burda, R., Wietfeld, C., Bauer, F. and Lüert, O., "GPS Community Map Generation for Enhanced Routing Methods based on Trace-Collection by Mobile Phones",1st International Conference on Advances in Satellite and Space Communications (SPACOMM), Colmar, France, IEEE Computer Society, Digital Object Identifier 10.1109/SPACOMM.2009.31, pages: 156 - 161, July 2009, Best Paper Award.

The paper describes a map generation system which relies on random individual contributions of GPS traced movements. In a typical use case, mobile phone users would join a specific community to contribute their movements along streets, roads or pathways in form of so called traces. Neither contributing subscribers nor the map generation need to have an a priori knowledge of the charted area. The approach presented here comprises the trace recording, the upload process to a common server and the processing algorithm for map generation. The problem of noisy data, resulting from GPS inaccuracies and random movements is addressed and countermeasures are proposed. One major perspective of this paper is the decomposition of a map into reasonable segments. In this context, the filter mechanism applied to the raw data is a key component for the deduction of precise street maps. Furthermore, the proof of concept is given and a guideline for a lower limit of active subscribers to achieve an operational system is derived.

Role-Based Connectivity Management with Realistic Air-to-Ground Channels for Cooperative UAVs: Ad-hoc aerial sensor networks leveraging MUAVs (Micro Unmanned Aerial Vehicles) are ideally suited to cost-efficiently explore unknown or hostile environments for example in case of incidents producing harmful gases or radiation. In this manuscript we present results on the investigations of communication-aware steering algorithms for cooperative MUAV swarms. The mission objective is to achieve a maximum spatial exploration efficiency with the simultaneous ability to self-optimize the communication links by exploiting controlled mobility. While our previous work has mainly considered the performance of the Air-to-Air mesh network, in this paper we focus on the Air-to-Ground-link connectivity control. To achieve appropriate communication links to a central sensor data sink even while exploring larger search areas, an agent-based role management strategy is used to provide suitable multi-hop connectivity. The novel algorithms are investigated for static as well as dynamically changing environments. Key results include a detailed realistic aerial channel characterization and network dimensioning analysis considering numbers of MUAVs and density of ground stations vs. exploration speed and sensor data latency.
