    Decentralized decision making in adaptive multi-robot teams
    (it - Information Technology: Vol. 60, No. 4, 2018) Geihs, Kurt; Witsch, Andreas
    We present our decision support middleware PROViDE that facilitates decentralized decision making in multi-robot teams operating in highly dynamic environments with potentially unreliable communication channels and noisy sensors. Achieving an adaptive team behavior in such an environment is a challenge because the specific conditions require a fully decentralized decision process. The design of PROViDE borrows inspiration from human decision making processes. PROViDE supports replication of proposals, conflict resolution, and final team-decision making. For each of these steps a choice of methods is offered to the developer to provide flexibility for different application requirements and characteristics of execution environments. PROViDE is integrated into a comprehensive modeling framework for multi-robot systems. The main contributions of this paper are twofold: For the development of adaptive multi-robot teams we discuss requirements for a middleware that supports decentralized decision making in dynamic and adverse environments, and we demonstrate the effective and coherent integration of a set of domain-dependent decision support protocols into a middleware framework.

    IAL: An Information Abstraction Layer for IoT Middleware
    (INFORMATIK 2020, 2021) Günter, Andrei; Schwarzer, Christopher; König, Matthias
    The internet of things is an ever-expanding world of connected devices and services. Through observation of analog and digital processes, plenty of information is continuously produced. More than often, the information thus obtained is tailored to serve one separate purpose. Existing architectures omit the fact that partial results can be enriched with meta information and can be shared among network participants while information is processed. We show that enriched and simplified information packages can be shared to facilitate cooperation between constrained and smart devices as well as to serve for system optimization. In this work, we propose an implementation of the so-called information abstraction layer which serves as collective resource for querying mechanisms to provide information. To emphasize and illustrate the need for a standardized information abstraction layer into existing middleware, we outline a realistic example of use and introduce concepts to build and evaluate shared information in networks.

    Quo vadis, AUTOSAR?
    (INFORMATIK 2017, 2017) Jakobs, Christine; Tröger, Peter
    AUTOSAR is the de-facto standard for developing automotive software. It is utilized by leading car manufacturers and suppliers as a common platform for software portability and interoperability. Future car applications such as autonomous driving and Internet service usage change the static deployment model on single ECUs towards the classic idea of a dynamic distributed system. This paper identifies properties of AUTOSAR which do not match to such upcoming scenarios. We discuss how established patterns from distributed software development may contribute to an improved version of AUTOSAR that is more suited for current and future applications.

    Towards a Robust, Self-Organizing IoT Platform for Secure and Dependable Service Execution
    (Tagungsband des FB-SYS Herbsttreffens 2019, 2019) Eichhammer, Philipp; Berger, Christian; Reiser, Hans P.; Domaschka, Jörg; Hauck, Franz J.; Habiger, Gerhard; Griesinger, Frank; Pietron, Jakob
    In the IoT, resilience capabilities increasingly gain traction for applications, as IoT systems tend to play a bigger role for both the proper functioning of our society and the survivability of companies. However, hardening IoT service execution against a variety of possible faults and attacks becomes increasingly difficult as the complexity, size and heterogeneity of IoT infrastructures tend to grow further and further. Moreover, many existing solutions only regard either specific faults or security issues instead of following a unifying approach. In this position paper, we present our research project called SORRIR, which essentially is an approach to develop a self-organizing IoT platform for dependable and secure service execution. One of our main ambitions is to support developers by separating application development (app logic) from resilience properties, so that developers can configure a desired resilience degree without proper knowledge of underlying technical, implementation-level details of employed resilience mechanisms. Further, we consider security requirements and properties as an integral component of our platform.
