Poster: Dependency-Aware Operator Placement of Distributed Stream Processing IoT Applications Deployed at the Edge

In the last few years, the number of IoT applications that rely on stream processing has increased significantly. These applications process continuous streams of data with a low delay and provide valuable information. To meet the stringent latency requirements and the need for real-time results that they require, the components of the stream processing pipeline can be deployed directly onto the edge layer to benefit from the resources and capabilities that the swarm of edge devices can provide. In this poster, we outline some ongoing research ideas into deploying stream processing operators onto edge nodes, with the goal of minimizing latency while ensuring that the constraints of the devices and their network capabilities are respected. More precisely, we provide a modeling of the semantics of the operators that considers the interactions between different operators, the parallelism of concurrent operators, as well as the latency and bandwidth usage.
