Mitigating Collisions via Inter-UE Coordination in 5G New Radio Vehicle-to-Everything Sidelink Communications
The evolution of 5G New Radio (NR) Vehicle-to-Everything (V2X) communication is opening new horizons for both road and rail transport. Designed to support direct Sidelink (SL) communication between vehicles, infrastructure, and other road users, NR V2X enhances safety and enables time-critical applications such as collision avoidance and intersection coordination. While originally targeted at automotive use cases, NR V2X is now being considered as a key enabler for next-generation train communication systems, offering the potential to support wireless train backbones and consist networks in scenarios where infrastructure-based coverage is limited. This presentation will examine the current limitations of decentralized 5G NR V2X Sidelink scheduling mechanisms, particularly in Mode 2(a), where autonomous resource selection can suffer from issues such as the hidden-node problem. We will explore cooperative scheduling strategies, also referred to by 3GPP as Inter-UE coordination, which aim to improve the reliability of resource allocation in such decentralized scenarios. A candidate implementation of a cooperative scheduling mechanism will be presented, along with preliminary performance evaluation results that illustrate its potential and highlight remaining challenges.

Blockchain and Digital Identity: SSI, DIDs, VCs, EBSI
In this presentation we explore the application of blockchain technology in the realm of digital identity, focusing on Self-Sovereign Identity (SSI), Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), and the European Blockchain Services Infrastructure (EBSI). We begin by explaining how DIDs enable secure, self-sovereign identities that give individuals control over their personal data, moving away from centralized identity models. We then delve into VCs, which allow for the verification of identity credentials without relying on third parties, enhancing privacy and security. Finally, we discuss EBSI's role as a European initiative to leverage blockchain for cross-border services. By integrating these technologies, blockchain has the potential to revolutionize identity management, providing a secure, decentralized, and user-centric approach for the digital age.

Safe and Secure AI/ML-driven Autonomous Vehicles? A distributed problem requiring distributed systems solutions
Currently, there is a substantial push towards autonomous vehicles (AV) in the market. However, autonomous vehicles, though using extensive fault-tolerance e.g., in x-by-wire functions, are still not quite safe from an accidental faults’ perspective, leave alone malicious faults. Furthermore, the growing number of recent AV architectures hinging on the advancements in AI/ML models, given their functional power, must be put in context with an equally significant number of related serious or fatal accidents. These pitfalls have been very slowly recognized by carmakers, with potentially harming results. Simultaneously enforcing unavoidable properties of Safety and Security in the autonomous vehicles ecosystem is by nature a distributed problem. I advance by suggesting to address it with distributed systems paradigms, under the umbrella of cyber resilience. Namely, I will discuss how in-car architectures might evolve to achieve fault and intrusion resilience of ECUs at system level, as well as reconciling the data-level stochastic nature of AI/ML paradigms with the determinism of driving control theory at system level, leveraging the best from both worlds: trustworthiness and intelligence.
