|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.

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.
|First Working Meeting
The first official working meeting with all partners of the project was held in Munich from 01.-02.07.2019. Besides taking a tour of the AED facilities we had many fruitful discussions and were able to progress in the project. Different architectures of hardware and software were evaluated as part of the meeting and many important decisions were made. The first milestone is already in sight!
DELIA project kick-off was held on the 11th February 2019 in Hamburg at the ZAL TechCenter. Now the work can start!
