Title: Contribution to Enhancing Trust and Security in Internet of Things (IoT) Networks
Abstract: After briefly introducing remote attestation protocols, we will present CRAFT, the first continuous remote attestation framework designed to enhance trust and security within networks of connected objects (IoT devices). This framework enables connected devices to use any existing remote attestation solution and adapt the protocol used based on the environment in which they operate. CRAFT relies on a set of messages designed to meet various functional and security requirements. It is based on a generic definition of a network of connected objects and has also undergone a security analysis to demonstrate its resilience to attacks targeting IoT networks. We will also present several simulations, carried out using the Omnet++ discrete event simulator, which highlight the framework’s strong performance.

Title: OCluster Selection for Task Offloading: A Bandit Problem Perspective
Abstract: Task allocation to the most suitable cluster of accelerators is a critical challenge in modern distributed and heterogeneous computing environments. Each cluster may differ in performance, availability, and communication cost, making the optimal scheduling of tasks a complex combinatorial problem. This scheduling problem is NP-hard, meaning that finding the exact optimal allocation is computationally infeasible in real time, especially under dynamic system conditions. As a result, heuristic and learning-based methods are commonly used to make near-optimal decisions efficiently. One promising approach is to model the problem as a Multi-Armed Bandit (MAB), where each cluster is treated as an arm with unknown performance characteristics. The MAB framework allows the system to balance exploration of different clusters and exploitation of the best-performing ones, leading to adaptive and low-overhead task offloading strategies.

Title: A decade of LPWAN IoT: what’s ahead?
Abstract: LPWAN technologies targeting the Internet of Things (IoT) domain have been around for about a decade. They provide long-distance connectivity to battery-operated devices that were once difficult to connect with multi-hop approaches based on short communication technologies. Coupled with the availability of very powerful and affordable microcontrollers, new challenging applications in sensing, monitoring & surveillance applications that were before difficult to deploy can now be considered for out-of-the-box deployment. Among those technologies, LoRa from Semtech can be considered the leading LPWAN technology operating in the unlicensed bands outside of China. In this talk, we will first introduce selected LPWAN technologies and how they operate. We will then focus on LoRa and present the challenges that still exist in efficiently share the radio resource when deploying large scale LoRa networks, including non-terrestrial networks. In conclusion, we will try to give our vision of what’s ahead in the LPWAN ecosystem.

Title: Digital sovereignty: what impact on telecommunications infrastructures?
Abstract: Questions of digital sovereignty have received renewed attention in the current context, due to the increasingly influential role of the GAFAM companies and rising international tensions, particularly in Europe. Regulations have been implemented to protect European citizens’ personal data (GDPR), to regulate the development of AI algorithms (AI Act), and to structure the field of digital services (Digital Services Act). The aim of this presentation is to examine the role that sovereignty plays in the development of the underlying digital infrastructure—communication networks and data centers. We will review the evolution of the Internet, 6G, and cloud computing in order to identify connections between technological developments, scientific innovations, and issues of sovereignty.

Title: Large scale distributed sensing and data storage using CAVs: Turning vehicular networks into city-wide perception hubs
Abstract: The growth in the number of mobile devices today result in an increasing demand for large amount of rich content to support numerous applications. It is however challenging for the current cellular networks to deal with such increasing demand, both in terms of cost and bandwidth that are necessary to handle the “massive” content generated and consumed by mobile users in an urban environment. This is partly due to the connection-centric nature of current mobile systems. Alternatively, the technological advancement in modern vehicles allow us to harness their computing, caching and communication capabilities to supplement infrastructure network while enabling numerous location-based services towards city smartification. It is now imaginable to recruit connected and autonomous vehicles (CAVs) to collect, store and share heterogeneous data on urban streets in order to provide citizens with a various set of such services. In this talk, our aim is to present some of our past results and future research directions on how to efficiently collect and store contents by and within the vehicles themselves in the vicinity of the consumers, aka the urban mobile user, while reducing bandwidth demand and cost. Hence, we will briefly discuss the necessity to define novel centrality metrics, based on the social interest of urban users, to identify and select the appropriate set of best candidate vehicles to perform urban data sensing and collection in a distributed way. Then, we show how complex networks principles and game-theoretic approaches can be leveraged in order to realize a social-aware data storage system to perform collaborative content caching in an urban environment. Discussing how such solutions, necessitating no infrastructure support, could allow novel usages at smart city’s scale will conclude the talk.
