a Ping Sensor of your DR Server and a Service Sensor of the same. Our results showed that the k-Shell algorithm of the proposed framework produces a raster based on 250k observation streams in under 0.5 s using a state-of-the-art workstation. You can create a Factory Sensor to monitor e.g. For our performance experiments, we generated several different spatio-temporal stream data sets based on the radiation deposits in the Fukushima region after the nuclear accident of 2011 in Japan.
The proposed framework includes a two-panel, spatio-temporal grid-based index and several algorithms, namely the Shell and k-Shell algorithms, to estimate individual grid cells efficiently and adaptively for different sampling scenarios. In detail, we designed and implemented a novel stream query operator framework that extends general-purpose DSEs. In this article, we present an approach leveraging data stream engines (DSEs) to achieve scalable, high-throughput inverse distance weighting (IDW). With very large numbers of concurrent observation streams, novel algorithms are necessary that integrate streams into rasters, or other continuous representations, continuously in real time. In-depth analysis of such spatial fields is often based on a continuous representation. Using sensor data streams enables real-time applications such as environmental hazard detection, or earthquake, wildfire, or radiation monitoring. With advances in technology and an increasing variety of inexpensive geosensors, environmental monitoring has become increasingly sensor dense and real time.
