    Towards quality-aware simulations on mobile devices
    (Informatik 2014, 2014) Dibak, Christoph; Koldehofe, Boris
    Numerical simulations are import for analyzing Big Data and realizing applications in the Internet of Things. Running numerical simulations on mobile devices makes analyzing and reasoning about Big Data ubiquitous. However, mobile devices are limited in energy and compute resources, and connectivity to a dedicated infrastructure like a cloud cannot always be assured. Therefore, we propose to run the simulation on a distributed environment consisting of a mobile device and the cloud. This environment has a number of constraints for compute and network resources that need to be considered for providing simulation results in time and with high quality. In this paper we propose an architecture for mobile simulations and list challenges for realizing them.

    Transitions for Increased Flexibility in Fog Computing: A Case Study on Complex Event Processing
    (Informatik Spektrum: Vol. 42, No. 4, 2019) Luthra, Manisha; Koldehofe, Boris; Steinmetz, Ralf
    Fog computing is envisioned to enable profound applications in the Internet of Things (IoT). A key characteristic of such applications is the need to exchange vital information between distinct IoT devices in the form of event notifications, e. g., traffic conditions when performing traffic monitoring. Complex event processing (CEP) is a powerful paradigm to overcome the information gap from observing primary sensor data by IoT devices to delivering event notifications to the IoT application users. However, to perform CEP in a highly dynamic IoT environment, e. g., involving mobile and heterogeneous devices, require an extremely flexible design of a CEP system to adaptively meet the changing requirements and conditions in which the CEP system is executed.
