Operator placement for data stream processing based on publisher/subscriber in hybrid cloud-fog-edge infrastructure
Cluster Computing (KLU-CLUS), Volume 27, Issue 3Pages 2741–2759https://doi.org/10.1007/s10586-023-04065-zAbstractInternet of Things (IoT) systems generate a vast volume of data to process, and the volume of data generated by the IoT will continue to expand exponentially in the future. Due to the large-scale nature of such systems and their geographically ...

Language-integrated privacy-aware distributed queries
Proceedings of the ACM on Programming Languages (PACMPL), Volume 3, Issue OOPSLAArticle No.: 167, Pages 1–30https://doi.org/10.1145/3360593Distributed query processing is an effective means for processing large amounts of data. To abstract from the technicalities of distributed systems, algorithms for operator placement automatically distribute sequential data queries over the available ...

Understanding the Behavior of Operator Placement Mechanisms on Large-Scale Networks
Middleware '18: Proceedings of the 19th International Middleware Conference (Posters)Pages 19–20https://doi.org/10.1145/3284014.3284024Operator Placement (OP) mechanism dictates the mapping of compute units, aka. operators on the network infrastructure based on the performance objectives requested by the end-user. The behavior of a placement is strongly influenced by the underlying ...

Adapting to Dynamic User Environments in Complex Event Processing System using Transitions
DEBS '18: Proceedings of the 12th ACM International Conference on Distributed and Event-based SystemsPages 274–277https://doi.org/10.1145/3210284.3226051Complex Event Processing (CEP) system enables extraction of higher-level information from real-time data streams produced by distributed sources. However, these systems are subject to changes in the user environment e.g., density of sources, rate at ...

TCEP: Adapting to Dynamic User Environments by Enabling Transitions between Operator Placement Mechanisms
DEBS '18: Proceedings of the 12th ACM International Conference on Distributed and Event-based SystemsPages 136–147https://doi.org/10.1145/3210284.3210292Operator placement has a profound impact on the performance of a distributed complex event processing system (DCEP). Since the behavior of a placement mechanism strongly depends on its environment; a single placement mechanism is often not enough to ...
