    International audienceEmbedded electronic systems in vehicles are of rapidly increasing commercial importance for the automotive industry. While current vehicular embedded systems are extremely limited and static, a more dynamic configurable system would greatly simplify the integration work and increase quality of vehicular systems. This brings in features like separation of concerns, customised software configuration for individual vehicles, seamless connectivity, and plug-and-play capability. Furthermore, such a system can also contribute to increased dependability and resource optimization due to its inherent ability to adjust itself dynamically to changes in software, hardware resources, and environment condition. This paper describes the architectural approach to achieving the goals of dynamically self-configuring automotive embedded electronic systems by the EU research project DySCAS. The architecture solution outlined in this paper captures the application and operational contexts, expected features, middleware services, functions and behaviours, as well as the basic mechanisms and technologies. The paper also covers the architecture conceptualization by presenting the rationale, concerning the architecture structuring, control principles, and deployment concept. In this paper, we also present the adopted architecture V&V strategy and discuss some open issues in regards to the industrial acceptance

    Internet of things: Vision, applications and research challenges

    Get PDF
    The term “Internet-of-Things” is used as an umbrella keyword for covering various aspects related to the extension of the Internet and the Web into the physical realm, by means of the widespread deployment of spatially distributed devices with embedded identification, sensing and/or actuation capabilities. Internet-of-Things envisions a future in which digital and physical entities can be linked, by means of appropriate information and communication technologies, to enable a whole new class of applications and services. In this article, we present a survey of technologies, applications and research challenges for Internet-of-Things

    Strengthening Trust in the Future ICT Infrastructure

    Moving towards a hyperconnected society in the forthcoming “zettabyte” era requires a trusted ICT infrastructure for sharing information and creating knowledge. To advance the efforts to build converged ICT services and reliable information infrastructures, ITU-T has recently started a work item on future trusted ICT infrastructures. In this paper, we introduce the concept of a social-cyber-physical infrastructure from the social Internet of Things paradigm and present different meanings from various perspectives for a clear understanding of trust. Then, the paper identifies key challenges for a trustworthy ICT infrastructure. Finally, we propose a generic architectural framework for trust provisioning and presents strategies to stimulate activities for future standardization on trust with related standardization bodies

    Industry-Academia Research toward Future Network Intelligence:The NG-CDI Prosperity Partnership

    Ever since the first automation provided by the introduction of the Strowger telephone exchange in the late 19th century, networks have been increas- ingly automated. Fast forward to 2022, and the challenge facing network providers is scaling up this level of automation considering massive increases in complexity, new levels of agility to operate ser- vices, and rising demand from customers within the modern telecommunications ecosystem. This article describes a significant new industry-academia part- nership to address these challenges: Next Gener- ation Converged Digital Infrastructure (NG-CDI) is creating a vision for the building and operation of a future-proof network infrastructure and its autonomic management. In this article, we high- light three exemplar activities within the NG-CDI research program that illustrate the benefits of tak- ing a highly collaborative interdisciplinary approach and show how academia and industry working closely together have delivered a range of direct and positive impacts on business

    Extending P4 in-band telemetry to user equipment for latency-and localization-aware autonomous networking with AI forecasting

    Get PDF
    In beyond-5G networks, detailed end-to-end monitoring of specific application traffic will be required along with the access-backhaul-cloud continuum to enable low latency service due to local edge steering. Current monitoring solutions are confined to specific network segments. In-band network telemetry (INT) technologies for software defined network (SDN) programmable data planes based on the P4 language are effective in the backhaul network segment, although limited to inter-switch latency; therefore, link latencies including wireless and optical segments are excluded from INT monitoring. Moreover, information such as user equipment (UE) geolocation would allow detailed mobility monitoring and improved cloud-edge steering policies. However, the synchronization between latency and location information, typically provided by different platforms, is hard to achieve with current monitoring systems. In this paper, P4-based INT is proposed to be thoroughly extended involving UE. The INT mechanism is designed to provide synchronized and accurate end-to-end latency and geolocation information, enabling decentralized steering policies, i.e., involving UE and selected switches, without SDN controller intervention. The proposal also includes an artificial-intelligence-assisted forecast system able to predict latency and geolocation in advance and trigger faster edge steering

    In this work the self-organising potential of the CATNETS allocation mechanism is described to provide a more comprehensive view on the research done in this project. The formal description of either the centralised and decentralised approach is presented. Furthermore the agents' bidding model is described and a comprehensive overview on how the catallactic mechanism is incorporated into the middleware and simulator environments is given. --Decentralized Market Mechanisms,Centralized Market Mechanisms,Catallaxy,Market Engineering,Simulator Integration,Prototype Integration

    EXPLAINING THE ROLE OF SERVICE-ORIENTED ARCHITECTURE FOR CYBER-PHYSICAL SYSTEMS BY ESTABLISHING LOGICAL LINKS

    Get PDF
    In the context of the so-called fourth industrial revolution, cyber-physical systems (CPS) build the technological foundation for the increasing digitalisation of our world. Because guidelines to overcome challenges of building such systems (e.g. security concerns, missing know-how, and lack of standards) are scarce, researchers and practitioners alike have begun to analyse the role of the mature paradigm of service-oriented architecture (SOA) in implementing CPS. However, the relationship between SOA and CPS is not entirely understood. To close this gap, we analyse SOA’s role for CPS based on a concept-driven literature review. The analysis of 12 publications that address the interrelation between SOA and CPS yielded four groups of CPS benefits that can be achieved by leveraging SOA. Combining these benefits with architectural layers and SOA’s design principles, we identify logical links that explain the role of SOA for CPS. Future research might concentrate on dominant patterns to scrutinise how a specific benefit can be achieved by leveraging SOA. Designers of CPS can leverage the identified patterns to understand the importance of specific characteristics of SOA to address the unique requirements of their CPS
