The 2024 meeting of the professional and scientific community of automotive communications on October 22-23, 2024, in Frankfurt, Germany, highlighted several hot topics, such as actual deployment questions of cooperative intelligent transport systems, relevant activities of the automotive industry, the current state of the art in the field of protection of vulnerable road users and optimal usage of radio resources. László Bokor was involved in discussions of C2C-CC activities requiring advanced simulation modeling of V2X communication technologies and solutions.

Our Head of Lab, Vilmos Simon was elected by the HUN-REN Headquarters Governing Board as a member of the Scientific Council, among the members of the College of Mathematics and Natural Sciences

HUN-REN was established to manage and operate a centrally funded, independent research network that is a cornerstone of Hungarian scientific life. The researchers of its eleven research centers and seven research institutes, as well as its 116 supported research groups operating at universities and other public institutions, are in the fields of mathematics and natural sciences, life sciences, and they carry out basic and applied research in the most diverse areas of the humanities and social sciences. The Scientific Council supports the work of the Governing Board, comments on proposals of strategic importance prepared for the Governing Board, prepares strategic proposals and carries out an annual evaluation and decides on the powers delegated to it by the Governing Board.

Presentation at VAE 2018

Our colleague Zsolt Szendrei presented the article “Zs. Szendrei , N. Varga, L. Bokor: A SUMO-based Hardware-in-the-Loop V2X Simulation Framework for Testing and Rapid Prototyping of Cooperative Vehicular Applications” on the 23rd of May 2018 at the 2nd International Conference on Vehicle and Automotive Engineering – 23-25 May 2018, University of Miskolc, Hungary (VAE 2018).

  

Abstract. Vehicle-to-Anything (V2X) technologies aim at providing globally standardized communication tools to efficiently transmit information between all players of the transportation ecosystem. Based on such extensive data exchange between traffic objects V2X helps to create an advanced domain of transportation called Cooperative Intelligent Transportation Systems (C-ITS) where an ever-growing scale of cooperative vehicular applications/services facilitate enhanced safety and comfort on the road and lead towards fully automated transportation in the future. C-ITS relies on a complex architecture consisting of a cross-layer op-timized sophisticated protocol stack, hybrid radio access solutions, computing al-gorithms, decision schemes, special interfaces, internet-of-things (IoT) integra-tion, etc. Moreover, C-ITS and the support of cooperative use-cases demand high reliability, enhanced Quality of Service/Quality of Experience (QoS/QoE), and rock-solid hardware/software implementations working efficiently and securely even in the most complicated environments including extreme traffic circumstanc-es or unpredictable actions. Therefore, deliberate system testing is a crucial and strategic process, especially when we are closing to the wide-scale deployment phase of real-life C-ITS solutions. Our proposed hardware-in-the-loop (HiL) V2X simulation framework was designed to offer a cost-efficient and simple toolset for testing and rapid prototyping of cooperative vehicular solutions by partially replacing costly, time-consuming and oftentimes dangerous field tests with an easy to install, tabletop laboratory test- and development suite.

Presentation in Žabljak – IT 2018

Our colleagues Norbert Varga and László Bokor together with co-authors Ivana Ognjanović and Ramo Šendelj from Montenegro presented their accepted paper entitled “On the mobility management performance of NEMO-based nested wireless body area networks” in Žabljak at the 23. Information Tehnology (IT 2018) conference.

Abstract:
Given the currently fast evolution of wireless access technologies, high-performance mobile devices and wide variety of wearable medical sensors, electronic and mobile healthcare (eHealth and mHealth) services are receiving particular attention nowadays. Several mHealth application scenarios strongly rely on mobile or embedded devices interconnected with medical sensors via Wireless Body Area Networks (WBANs). The vast majority of these services require strict medical level Quality of Service (QoS) and Quality of Experience (QoE) provision. Emergency use-cases like remote patient monitoring, tele-consultation and guided surgical intervention demand real-time communication and appropriate connection quality during any mobility event. In many cases the mHealth WBANs are nested into other overlay access networks around the patient. To fulfil the quality requirements of such applications, during the various mobility scenarios not only a single mobile entity has to be considered, but also entire nested WBANs (moving between different networks) have to be taken into account. If network layer mobility management is required (like in case of inter-technology handovers under heterogeneous radio coverages), still NEMO Basic Support (RFC 3963) is the most common standardized approach to be implemented. Motivated by this, the paper investigates mobility management performance issues of NEMO-based nested WBANs. The evaluation is based on INET/OMNeT++ simulations and transport layer characteristics.

5G V2X demonstration on Magyar Telekom’s 5G Verticals conference

Our colleagues Norbert Varga and László Bokor together with Péter Hegyi from Nokia Bell Labs demonstrated their latest results on simulation of multiple dynamic V2X communication / service provision environments in heterogeneous 5G telco cloud systems. The demonstration was held during Magyar Telekom’s 5G VERTICALS – NEXT GENERATION BUSINESS CONFERENCE and showcased 5G V2X communication scenarios where dynamic V2X communication / service provision environments are simultaneously available for connected/autonomous vehicles and other users with highly different communication characteristics and network usage profile. Advanced 5G features like network slicing, application scaling, hybrid multiaccess V2X communication and adaptive network function placement have been applied to demonstrate how use-cases of connected and autonomous vehicles can be efficiently supported in 5G telco cloud systems.

 

 

Intelligent traffic light controller systems – Paper presentation on ITST 2017

Our colleagues Norbert Varga and László Bokor together with András Takács, József Kovács and László Virág from Commsignia Ltd. have presented their results on  V2X communication-centric traffic light controller systems during the 15th International Conference on ITS Telecommunications (ITST) in Warsaw, Poland. The presented work (available on ieeexplore) focuses on advanced traffic light / traffic signal controller systems which will play an important role in adaptively and dynamically coordinating individual traffic lights of near future smart cities to manage city-wide objectives of traffic operations using vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) communication  techniques (together referred as V2X).  Dynamic real-time information exchange between all the players of the traffic controlling ecosystem and fostering cooperative urban mobility are the main goals of the proposed architecture while the presented testbed showcases the authors’ proof-of-concept implementation of the proposed scheme.
