A Spatially-Aware Publish-Subscribe Middleware for IoT Applications
Philipp Ungrund, Kurt Rothermel, Sukanya Bhowmik
Spatial and proximity awareness are critical enablers for efficient communication in Cyber-Physical Systems (CPS) and the Internet of Things (IoT). However, the lack of suitable mi…
Multicast-partitioning in Time-triggered Stream Planning for Time-Sensitive Networks
Heiko Geppert, Frank Dürr, Simon Naß +1
Multicast allows sending a message to multiple recipients without having to create and send a separate message for each recipient. This preserves network bandwidth, which is partic…
Grand Perspective: Load Shedding in Distributed CEP Applications
Henriette Röger, Sukanya Bhowmik, Kurt Rothermel
In distributed Complex Event Processing (CEP) applications with high load but limited resources, bottleneck operators in the operator graph can significantly slow down processing o…
gSPICE: Model-Based Event Shedding in Complex Event Processing
Ahmad Slo, Sukanya Bhowmik, Kurt Rothermel
Overload situations, in the presence of resource limitations, in complex event processing (CEP) systems are typically handled using load shedding to maintain a given latency bound.…
