    SCoIoT: Swarm-Computations for the Internet of Things
    (IEEE, 2021) Scherb, Christopher; Bürklin, Pascal; Tschudin, Christian [in: 2021 International Conference on Computer Communications and Networks (ICCCN)]
    Nowadays, most network systems are based on fixed and reliable infrastructure, but with Internet of Things (IoT), smart home and smart city systems are used more and more in mobile scenarios and vehicles become connected. Often low power mobile devices are supported by cloud computing capabilities. However, infrastructure may not be available everywhere, where mobile devices are used and local information is often only required locally, thus do not need to be uploaded into the cloud. SCoIoT is based on novel Information Centric Networking communication pattern and is designed to support cooperative computations without requiring new infrastructure or even in absence of infrastructure due to the device to device communication pattern. Thereby, nodes voluntarily participate in computations and help to spread the computation to enable further nodes to participate in the computation and to share the results. SCoIoT utilizes Append-only-Log technology for synchronization and verification of requests and results.

    Tangle centric networking
    (ACM, 2021) Scherb, Christopher; Grewe, Dennis; Tschudin, Christian [in: ICN '21. 8th ACM Conference on Information-Centric Networking]
    Today's Internet is heavily used for multimedia streaming from cloud backends, while the Internet of Things (IoT) challenges the traditional data flow, with high data volumes produced at the network edge. Information Centric Networking (ICN) advocates against a host-centric communication model using content identifiers decoupling content from a location, and therefore, promising for distributed edge computing environments. However, the resulting coupling of data to content identifiers in ICNs introduces new challenges regarding dissemination of large data volumes and services and synchronization across multiple consumers. We present Tangle Centric Networking (TCN) - a decentralized data structure for coordinated distribution of data and services for ICN deployments. TCN simplifies the management of data and service changes and updates them accordingly in network nodes using principles of Tangles. Using simulations, first implementations of TCN show improvements in data discovery as well as less synchronization overhead of large volumes of data compared to a state-of-the-art ICN system.
