Distributed, Extendable, Lightweight, open, reliable, servIce-oriented Architecture for next-gen mobility

Motivation

Autonomous vehicles and aircraft can fundamentally impact urban mobility in the future. However, to realize innovative mobility concepts, multiple research questions need to be answered. Today’s electronic components for mobility applications consist of various proprietary, isolated systems which use different communication channels. These channels are often incompatible and are unsuitable for future needs in regards to bandwidth, real time capability and interoperability. This structure slows new developments because information cannot be shared easily between hardware components and hinders a common software development.

Goals and Approach

In order to realize these technological challenges for safety and time critical applications, communication systems with high data rates and little latency which are based on open industry standards need to be identified. A modular, decentralized communication and processing platform will be developed in order to ensure the targeted flexibility and determinism. This DELIA platform consists of separated modules which and connected through a real time capable fiber optics backbone with data rates up to 25 Gbit/s. Each module is based on multi core processors and FPGA (Field Programmable Gate Array) technology to guarantee a well-defined and reproduceable data processing behavior. The modules include functions for data transport as well as custom applications for attached control devices, sensors and actors. In the test setup the various functionalities will be demonstrated and tested.

Innovation and Outlook

An autonomous aircraft and vehicle, such as imagined in the Pop.Up Next concept by Airbus, Audi and Italdesign, allows a flexible dual use of passenger or cargo compartments which can be attached to driving or flying transport platform during their journey. The DELIA platform can provide an essential step towards realization of this concept. The competences of the consortium will be used to develop the DELIA platform and through workshare with the two universities, the innovation capabilities of the highly specialized SME (small and medium enterprises) will be increased.

Short Paper on Resilience of Virtualized Embedded IoT Networks by University of Hamburg accepted for 2. KuVS Fachgespräch “Network Softwarization (2020)“ Embedded IoT networks are the backbone of safety-critical systems like smart factories, autonomous vehicles, and airplanes. Therefore, their resilience against failures and attacks should be a prior concern. The design of more capable IoT devices enables the flexible deployment of network services by virtualization but it also increases the complexity of the systems and makes them more error-prone. In this paper, we discuss the issues and challenges to ensure resilience in virtualized embedded IoT networks by presenting proactive and reactive measures. Third Working Meeting On the 2nd and 3rd of September 2020 the third official working meeting was held. Due to COVID-19 travel restrictions an as a precautionary measure, the working meeting was held virtually. Despite not meeting in person, we had a very productive meeting with a lot of fruitful discussions. Publication on Service-based Resilience in Embedded IoT Networks by University of Hamburg accepted for DSN 2020 DELIA leverages the virtualized embedded nodes to deploy and manage various mixed-criticality services flexibly. Apart from the service deployment and routing challenges for an efficient network design, guaranteeing the resilience of safety-critical services should also be a prior concern already in their design stage. In this study, we introduce a service-based network model as an MILP optimization problem for the efficient deployment of a service overlay to the embedded network by meeting QoS and resilience requirements. We show the complexity and boundaries of the problem and propose several heuristics to relax the service deployment phase and increase the fault-tolerance against node and link failures as a part of resilience goals. Our results indicate that the heuristics achieve results close to the optimum for small sizes of the problem significantly faster and can maintain the service availability for 90% of given failure scenarios in larger topologies.

Second Working Meeting On the 12th and 13th of February 2020 the second official working meeting was held at the University of Hamburg. A lot of intensive discussions where accompanied by demonstrations of research work conducted by the research group IT-Security and Security Management (Prof. Mathias Fischer). We are looking forward to a productive year. Continue reading “News Section”
