Cooperative driving with multiple communication technologies which complement each other opens new spaces for research and development, but also poses several challenges. The work we present tackles the fallback and recovery mechanisms that the longitudinal controlling system of a platoon of vehicles can implement as a distributed system with multiple communication interfaces. We present a protocol and procedure to correctly compute the safe transition between different controlling algorithms, down to autonomous (or manual) driving when no communication is possible. To empower the study, we also develop a new version of PLEXE, which is an integral part of this contribution as the only Open Source, free simulation tool that enables the study of such systems with a modular approach, and that we deem offers the community the possibility of boosting research in this field. The results we present demonstrate the feasibility of safe fallback, but also highlight that such complex systems require careful design choices, as naïve approaches can lead to instabilities or even collisions, and that such design can only be done with appropriate in-silico experiments."}],"issue":"8","publication":"IEEE Transactions on Mobile Computing","type":"journal_article","department":[{"_id":"534"}],"date_created":"2024-02-08T07:41:39Z"},{"publication_status":"published","date_updated":"2024-02-08T07:51:04Z","year":"2023","title":"Improving Platooning Safety with Full Duplex Relaying and Beamforming","status":"public","author":[{"last_name":"Hardes","first_name":"Tobias","full_name":"Hardes, Tobias","id":"35441"},{"last_name":"Klingler","first_name":"Florian","full_name":"Klingler, Florian"},{"full_name":"Sommer, Christoph","last_name":"Sommer","first_name":"Christoph"}],"conference":{"end_date":"2023-03-29","location":"Glasgow, Scotland, UK","name":"IEEE Wireless Communications and Networking Conference 2023","start_date":"2023-03-26"},"user_id":"35441","doi":"10.1109/WCNC55385.2023.10118843","publisher":"IEEE","_id":"51264","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Platooning is a promising application in the field of vehicular networks.

We do not require that these UAVs alter trajectory nor speed from those of their random, unrelated primary missions, so that these additional tasks can be executed with close-to-zero impact on the execution of their primary missions. Based on extensive computer simulations we show that, within a wide band of acceptable speeds, flight routes (up to a standard deviation of 300 m from the optimum) as well as altitudes, opportunistic relaying of transmissions via UAVs can yield a benefit to system performance that is on the same order of magnitude as that of optimally deployed UAVs. We further show that an opportunistic channel access control can reduce the total number of packet collisions by approx. 86 % compared to a scenario without any UAVs. Moreover, much of the reduction in impact due to suboptimal missions can be recovered simply by moderately increasing the number of UAVs."}],"date_created":"2024-02-08T07:42:11Z","department":[{"_id":"534"}],"type":"journal_article","author":[{"id":"35441","full_name":"Hardes, Tobias","last_name":"Hardes","first_name":"Tobias"},{"first_name":"Christoph","last_name":"Sommer","full_name":"Sommer, Christoph"}],"publication_identifier":{"issn":["0140-3664"]},"status":"public","year":"2023","title":"Opportunistic Airborne Virtual Network Infrastructure for Urban Wireless Networks","article_type":"original","publication_status":"published","date_updated":"2024-02-08T07:50:25Z","language":[{"iso":"eng"}],"_id":"51267","publisher":"Elsevier","user_id":"35441","doi":"10.1016/j.comcom.2023.06.003"},{"abstract":[{"text":"Many exciting future research topics in the field of Cooperative Autonomous Vehicles (CAVs) require the simulation of both connectivity and automation components.

Based on extensive computer simulations we demonstrate that, within a wide band of acceptable speeds, flight routes (up to a standard deviation of 300 m from the optimum), as well as altitudes, opportunistic relaying of transmissions via UAVs can yield a benefit to system performance that is on the same order of magnitude as that of optimally deployed UAVs. Moreover, much of the reduction in impact due to suboptimal missions can be recovered simply by moderately increasing the number of UAVs."}],"date_created":"2024-02-08T07:25:33Z","place":"Virtual Conference","type":"conference"},{"publication":"15th IEEE International Workshop on Wireless Sensor, Robot and UAV Networks","citation":{"mla":"Hardes, Tobias, et al. “Towards an Open-Source Fully Modular Multi Unmanned Aerial Vehicle Simulation Framework.” <i>15th IEEE International Workshop on Wireless Sensor, Robot and UAV Networks</i>, IEEE, 2022, doi:<a href=\"https://doi.org/10.1109/ICDCSW56584.2022.00060\">10.1109/ICDCSW56584.2022.00060</a>.","apa":"Hardes, T., Logan, D., Pritom, T.

In this paper, we present AirMobiSim, a modular and microscopic UAV simulation framework, which is available under a GPLv2 license. AirMobiSim provides the basis for the creation of kinematic and energy models for different UAV types. It can support an arbitrary number of UAVs and can be coupled with other simulators via open interfaces, for example to examine systems using wireless communication between UAVs.

However, UAVs are typically imagined to be provided specifically for this purpose. In this work, we study the effects of exploiting randomly passing UAVs at an urban intersection for the communication between vehicles on the ground. We show that a UAV, while following its pri- mary mission, can support cooperative driving vehicles in a purely opportunistic fashion by collecting periodic wireless broadcasts from vehicles and propagating all collected information periodically in an aggregated format.

Such platooning systems are usually focused on freeway scenarios and most of the current research is done for this use case. Especially in urban scenarios at traffic lights and intersections there is a lot of potential to increase the traffic efficiency and safety by applying platooning mechanisms. Most of the techniques used on freeways are not applicable for urban scenarios, as freeways are more or less a multi lane one-way road. In my PhD project I want to investigate platooning as an application for urban scenarios. For this I plan to examine platooning for signalized and non-signalized intersections in a first step, but also consider platoon formation strategies and driver models for human driven platoons. The end result should be a set of algorithms and strategies to make urban and rural traffic more efficient and safer by the use of platooning.

Platooning is one of the considered applications, helping cars to drive with very short safety gaps to improve road traffic capacity and to reduce air drag. A fundamental building block for such cooperative driving solutions is reliable and fast wireless communication. Usually, information from the leader of the platoon needs to be broadcast to all members, resulting in large interference ranges, or being relayed from car to car, introducing additional delays. We introduce a Full Duplex Relaying (FDR) system for use in platooning to overcome these limitations. Concentrating on IEEE 802.11p, we implement the system to explore the feasibility and also to conduct a first performance evaluation. Our results clearly demonstrate the significant performance gain, which at the same time allows to further reduce communication overhead and, thus, to safely increase platoon sizes 802.11p, we implement the system to explore the feasibility and also to conduct a first performance evaluation.

Yet, while there is ample research that illustrates its potential in freeway scenarios, the biggest challenges of traffic efficiency and safety lie in urban environments, which pose unique challenges: They are characterized by the presence of tight speed limits, intersections, traffic lights, and buildings. Moreover, work that has targeted such scenarios has, so far, not considered platoon formation strategies - or only considered idealized vehicle dynamics, platooning controllers, or wireless network dynamics. We fill this gap by investigating dynamic platoon formation at urban intersections controlled by regular traffic lights. We propose a fuel-efficient strategy for platoon formation at such intersections and investigate its performance using realistic simulation models of (all of) vehicle dynamics, platooning controllers, and wireless networking. Our investigation reveals both challenges in wireless networking as well as the potential of the proposed strategy to simultaneously save both 15 % of fuel and 14 % of travel time."}]},{"type":"conference","date_created":"2021-11-29T19:53:05Z","place":"G{\\\"{o}}ttingen, Germany","publication":"International Conference on Networked Systems (NetSys 2017)","citation":{"ieee":"T.

This also enables an uncensored communication and leads to a network owned by a community. Freifunk is such a project and it is based on wireless mesh networks. All participants provide an own wifi router (node) for transferring data between different devices. The routing protocol used in the Freifunk network of Paderborn is called Better Approach To Mobile Ad-hoc Networking advanced (B.A.T.M.A.N. IV or Batman-adv). It uses so called Originator Messages (OGM) to announce the existence of a node and to measure the quality of different links in the network. The Freifunk network in Paderborn consists of about 800 nodes that periodically broadcast OGMs. This leads to a substantial base load of ∼25 GByte per month and node. Instead of performing modifications in the real network, I create a simulation model of the current network structure and implement version IV of the B.A.T.M.A.N. routing protocol. The model is validated by using data from the real network. Based on this model I propose and evaluate five different opportunities to improve the base load without impairing other functionality of the network. The simulation results show that a combination of two improvements can lead to a reduction up to 90 %."}],"language":[{"iso":"eng"}],"_id":"51269","user_id":"35441","author":[{"full_name":"Hardes, Tobias","last_name":"Hardes","first_name":"Tobias","id":"35441"}],"status":"public","year":"2015","title":"Performance Analysis and Simulation of a Freifunk Mesh Network in Paderborn using B.A.T.M.A.N Advanced","date_updated":"2024-02-08T07:48:09Z"}]
