Maneuvers can be coordinated among participating vehicles and controlled by means of wireless communications. One of the most challenging scenario or application in this context is Cooperative Adaptive Cruise Control (CACC) or platooning. When it comes to realizing safety gaps between the cars of less than 5m, very strong requirements on the communication system need to be satisfied. The underlying distributed control system needs regular updates of sensor information from the other cars in the order of about 10 Hz. This leads to message rates in the order of up to 10 kHz for large networks, which, given the possibly unreliable wireless communication and the critical network congestion, is beyond the capabilities of current vehicular networking concepts. In this article, we summarize the concepts of networked control systems and revisit the capabilities of current vehicular networking approaches. We then present opportunities of Tactile Internet concepts that integrate interdisciplinary approaches from both control theory, mechanical engineering, and communication protocol design. This way, it becomes possible to solve the high reliability and latency issues in this context. }}, author = {{Dressler, Falko and Klingler, Florian and Segata, Michele and Lo Cigno, Renato}}, journal = {{Proceedings of the IEEE}}, publisher = {{IEEE}}, title = {{{Cooperative Driving and the Tactile Internet}}}, doi = {{10.1109/JPROC.2018.2863026}}, year = {{2018}}, } @article{6431, abstract = {{We present a complete simulation and experimentation framework for IEEE 802.11p. The core of the framework is an SDR-based OFDM transceiver that we validated extensively by means of simulations, interoperability tests, and, ultimately, by conducting a field test. Being SDR-based, the transceiver offers important benefits: It provides access to all data down to and including the physical layer, allowing for a better understanding of the system. Based on open and programmable hardware and software, the transceiver is completely transparent and all implementation details can be studied and, if needed, modified. Finally, it enables a seamless switch between simulations and experiments and, thus, helps to bridge the gap between theory and practice. Comparing the transceiver's performance with independent results from simulations and experiments, we underline its potential to be used as a tool for further studies of IEEE 802.11p networks both in field operational tests as well as for simulation-based development of novel physical layer solutions. To make the framework accessible to fellow researchers and to allow reproduction of the results, we released it under an Open Source license. }}, author = {{Bloessl, Bastian and Segata, Michele and Sommer, Christoph and Dressler, Falko}}, journal = {{IEEE Transactions on Mobile Computing}}, number = {{5}}, pages = {{1162--1175}}, publisher = {{IEEE}}, title = {{{Performance Assessment of IEEE 802.11p with an Open Source SDR-based Prototype}}}, doi = {{10.1109/TMC.2017.2751474}}, volume = {{17}}, year = {{2018}}, } @inproceedings{6432, abstract = {{Research on Cyber Physical Systems (CPS) has led to quite a number of astonishing technical solutions that are becoming standard in many application domains affecting our everyday life. The technical innovations range from control theory concepts to real-time wireless communication to networked control. Some of the most challenging applications include cooperative autonomous driving and industry automation. Despite all these great findings, our research community frequently lost track on the impact of individual human beings that are an integral part of the systems - both as a user as well as a source of disruption. We thus need a paradigm shift from classical CPS to Cyber Physical Social Systems (CPSS). Studying the impact of CPS on humans and vice versa, hybridization, i.e., machines and human users covering parts of the system function in deep interaction, is required as a novel core concept. This is also a basis for final public acceptance as a key to success of new technologies.

Dozens of broadcast protocols have been developed in recent years, including protocols for 1-hop broadcasting of vehicle status information (beaconing) and for geocasting-based applications. However, most of these protocols were designed for one application and cannot co-exist, nor can one broadcast solution meet the demands of all applications. These observations motivated our effort to develop a holistic Network layer for VANETs. We identify the need for making VANET broadcast context-aware, and for supporting four different classes of broadcast protocols, each with its own properties. These classes are not only able to co-exist on the same Network layer, but also to complement one another's functionality. Thus, large applications as well as more holistic Transport protocols can be designed by combining two or more broadcast classes. We discuss the specific characteristics of these classes and design candidate protocols for each class. }}, author = {{Dressler, Falko and Klingler, Florian and Sommer, Christoph and Cohen, Reuven}}, journal = {{IEEE/ACM Transactions on Networking}}, number = {{1}}, pages = {{17--30}}, publisher = {{IEEE}}, title = {{{Not All VANET Broadcasts Are the Same: Context-Aware Class Based Broadcast}}}, doi = {{10.1109/TNET.2017.2763185}}, volume = {{26}}, year = {{2018}}, } @inbook{6436, author = {{Geierhos, Michaela}}, booktitle = {{Integration und Toleranz}}, editor = {{Schnebel, Karin B. and Taubenböck, Andrea}}, isbn = {{978-3-86281-135-9}}, pages = {{288--292}}, publisher = {{Klemm+Oelschläger}}, title = {{{Freiraum zur individuellen Reflexion gemeinsamer Werte}}}, year = {{2018}}, } @inproceedings{4411, abstract = {{While a lot of research in distributed computing has covered solutions for self-stabilizing computing and topologies, there is far less work on self-stabilization for distributed data structures.

In this work, we present a self-stabilizing protocol for a distributed data structure called the hashed Patricia Trie (Kniesburges and Scheideler WALCOM'11) that enables efficient prefix search on a set of keys. The data structure has a wide area of applications including string matching problems while offering low overhead and efficient operations when embedded on top of a distributed hash table. Especially, longest prefix matching for $x$ can be done in $\mathcal{O}(\log |x|)$ hash table read accesses. We show how to maintain the structure in a self-stabilizing way.
