Szendrei Zsolt kollégánk előadást tartott a 2. International Conference on Vehicle and Automotive Engineering – 23-25 May 2018 (VAE 2018) nevet viselő konferencián, Miskolcon. Az előadott cikk címe: „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” volt.

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.

Kollégáink, Varga Norbert és Bokor László montenegriói szerzőtársaikkal, Ivana Ognjanović-csal és Ramo Šendelj-jel 2018 február 20-án adták elő az „On the mobility management performance of NEMO-based nested wireless body area networks” című cikküket a Žabljakban megrendezett 23. Information Tehnology (IT 2018) konferencián.

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.

Kollégáink, Varga Norbert és Bokor László kiállítóként részt vettek a 4. Magyar Jövő Internet Konferencia (MJIK 2017) programjában, és bemutatták a hybrid V2X (ITS G5 + 5G) rendszerek szimulációs vizsgálatával kapcsolatos legújabb eredményeiket.

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.

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.

Our colleagues Tamás Péteri, Norbert Varga and László Bokor have presented their novel results on mHealth QoE evaluation during the first International Young Researcher Summit on Quality of Experience in Emerging Multimedia Services (QEEMS 2017). Their paper (available online) focuses on pervasive and ubiquitous mHealth services that rely on heterogeneous network (HetNet) technologies comprising a combination of different cell types and different access technologies to ensure advanced communication solutions for critical services and patient-centric, customized, ’care anywhere’ mHealth applications. The paper presents the initial results of a medical Quality of Experience (m-QoE) evaluation procedure performed to analyse multimedia-intensive mHealth applications over heterogeneous mobile network access technologies.
