The process of designing and evaluating distributed Cyber-Physical Systems (CPSs) is not a trivial task. There are many challenges to tackle such as managing distributed resources, enabling communication between components, and choosing performance metrics to evaluate the “goodness” of the system. Smart Grids (SGs) are prominent representatives of CPSs, a particular type of Critical Infrastructure...
Many networking applications implement topology adaptations to cope with network dynamics. Related work focuses on the specific application, lacking a general model for topology adaptations. In this paper, we analyze 14 topology adaptations from two different application domains. Based on the derived characteristics, we propose a general topology adaptation model. We present the Topology Adaptation...
Graph-based topology control adapts wireless topologies to achieve certain target graph structures. Wireless sensor networks seem well-suited for the expectations (in particular those on provided energy savings) raised by topology control. Nevertheless, topology control has never made the breakthrough in real-world deployments. This work explores the reasons for this, identifying five practical obstacles...
Common conceptualizations of trust concern expectations about the future behavior of an entity. We focus on expectations about fair future behavior: this aspect was insufficiently formalized to date, prohibiting formal reasoning about fairness. In this paper, we extend our previous binary fairness model to a gradual one. We demonstrate the capabilities of gradual fairness in two scenarios: "distributing...
