The vehicle’s interaction with other vehicles and its surrounding infrastructure is gaining more and more importance to improve safety, efficiency and eco-friendly mobility. Obtaining new information from vehicle’s environment or rather cloud requires a transition in current automotive embedded devices, which leads to an increase of interfaces and complexity in the vehicle software. The limitations of vehicle’s on-board resources underline the necessity to use new concepts, which reduce the software complexity and amount of exchanged data.

This paper presents a novel phone app for use in the collection of flow data pertaining to users approaching and leaving a station before and after using a shared bike. Two novel functions were incorporated in the app to motivate adoption. One “Bike Station Querying” function is a search program indicating the location of nearby rental stations and the current availability of bikes. The other “Staged Route Planning” function is a route planning based on when the user would like to pick up and park the bike. Even while riding a bike, the user can alter their destination simply by pressing a button or muting the voice routing instructions. The collection of data in the background consumes very little power thanks to an algorithm designed to limit energy consumption. Data is uploaded to a cloud-based server for analysis by the operators or planners of bike sharing stations.

In this poster, we present the first experimental results of our OFDM-based Vehicular VLC (V-VLC) prototype. Our Bit Error Rate (BER) measurements show that for lower Modulation and Coding Schemes (MCS), the performance of our hardware-setup roughly behaves the same as it does in simulation for AWGN channel. However, for higher order MCS with high PAPR, the BER performance gets degraded due to non-linear behavior of LEDs, and deviates further from AWGN performance as the MCS order is increased. The obtained results suggest that unlike RF-Communications, where the focus is usually towards linearity of the amplifiers, for V-VLC, linearity within the whole system is required to achieve optimal performance.

Especially for cellular networks, the concept of connectivity maps and their benefits to predict upcoming communication characteristics that nodes will encounter has been well-studied and understood. In this paper, we analyze how this concept can be applied to communication in Vehicular Ad Hoc Networks (VANETs): We introduce connectivity maps for Vehicle-to-X (V2X) communication via the Intelligent Transport System (ITS) G5 standard of the European Telecommunications Standards Institute (ETSI) deployed on top of IEEE 802.11p. A reference implementation of these ITS-G5 connectivity maps is presented for connected vehicles and Roadside Units (RSUs) alike in a renowned V2X simulation framework. Results are provided for the evaluation of the functional correctness of the connectivity maps in simulation, in particular in comparison to real-world measurements, and core metrics in these maps are identified as well. Finally, it is shown how the communication of connected vehicles and RSUs is able to benefit from ITS-G5 connectivity maps, especially with increasing market penetration rates of V2X communication technologies.

Vehicles equipped with V2X communication technology are expected to be launched within a year. These vehicles will be shipped with a basic set of applications attributed to Cooperative Awareness (CA) and Decentralized Environmental Notification (DEN) services. Yet, research and standardization of advanced services is under way, e. g., to realize a Collective Perception of vehicles: With local perception sensors such as radar sensors continuously capturing the surroundings, previous research has shown the significant benefit of sharing such detected objects with other V2X-capable vehicles. In this paper, we present the current advancements compared to previous research as well as open research questions regarding the standardization process of a Collective Perception service in the European Telecommunications Standards Institute as well as its evaluation in the established simulation framework Artery.

As connected vehicles are envisioned to provide novel intelligent transportation systems, cyberattacks and security schemes are becoming an increasing concern. Several studies have shown that algorithms that make use of location information from other vehicles, such as vehicular platoon controllers, are vulnerable to message falsification attacks. Moreover, the ability for an attacking vehicle to appear as several vehicles through a so-called Sybil attack can significantly increase the severity of the attack. In this paper, we investigate how these attacks can be detected using Vouch location proof scheme (by identifying false location messages) and propose several reaction strategies to mitigate them. We also show through simulation that it is possible to prevent collisions by reacting appropriately to the false beacons in time while not reacting to false positives coming from the detector.

Inter-vehicle communications disclose rich information about vehicle whereabouts. Pseudonymous authentication secures communication while enhancing user privacy. To enhance location privacy, cryptographic mix-zones are proposed where vehicles can covertly update their credentials. But, the resilience of such schemes against linking attacks highly depends on the geometry of the mix-zones, mobility patterns, vehicle density, and arrival rates. In this poster, we propose “mix-zones everywhere”, a cooperative location privacy protection scheme to mitigate linking attacks during pseudonym transition. Time-aligned pseudonyms are issued for all vehicles to facilitate synchronous pseudonym updates. Our scheme thwarts Sybil-based misbehavior, strongly maintains user privacy in the presence of honest-but-curious system entities, and is resilient against misbehaving insiders.

With the large-scale deployment of connected and autonomous vehicles, the demand on wireless communication spectrum increases rapidly in vehicular networks. Due to increased demand, the allocated spectrum at the 5.9 GHz band for vehicular communication cannot be used efficiently for larger payloads to improve cooperative sensing, safety, and mobility. To achieve higher data rates, the millimeter-wave (mmWave) automotive radar spectrum at 76–81 GHz band can be exploited for communication. However, instead of employing spectral isolation or interference mitigation schemes between communication and radar, we design a joint system for vehicles to perform both functions using the same waveform. In this paper, we propose radar processing methods that use pilots in the orthogonal frequency-division multiplexing (OFDM) waveform. While the radar receiver exploits pilots for sensing, the communication receiver can leverage pilots to estimate the time-varying channel. The simulation results show that proposed radar processing can be efficiently implemented and meet the automotive radar requirements. We also present joint system design problems to find optimal resource allocation between data and pilot subcarriers based on radar estimation accuracy and effective channel capacity.

The vehicular social networks (VSNs) paradigm is a special class of vehicular networks (VANETs), where features and social aspects are taken into account. Starting from this concept, two different approaches can be applied in VSNs, which are the social network analysis (SNA) measures and the social networking concepts (SNC). In the past few years, several systems have been proposed to deal with traffic congestion problems. They rely on integrating computational technologies such as VANETs, central server, and roadside units. A number of systems employ a hybrid approach, this means that they still need an infrastructure support (central server or roadside unit) to achieve the goals of the system. In order to surpass that, this work deals with the question of how to manage the urban mobility, when an en-route event is detected, in an infrastructure-less environment and scalable fashion. To achieve that, the main goal is to apply VSNs to investigate how SNA measures and SNC can help in the urban mobility management in a distributed fashion. To this end, it was proposed the iMOB system, which is an intelligent urban mobility management system. The system consists of the 3-tier: the environment sensing (bottom tier), the vehicle ranking mechanism (middle tier), and the altruistic rerouting decision (upper tier). The SNA egocentric betweenness measure is applied in the middle tier and SNCs such as social interactions and virtual community were utilized in the upper tier. iMOB was evaluated in simulation-based experiments being able to outperform all its competitors in all assessed metrics. The results obtained lead us to conclude that the application of concepts and analysis of social network, in a vehicular environment, have great potential to improve the reliability and efficiency of urban mobility management systems in a practical and cost-effective way.
