Supporting Rule Generation and Validation on Environmental Data in EnStreaM
European Semantic Web Conference (ESWC), Heraklion, Crete, May 2012.

Detection rules represent one of the components of the rule models in event processing systems. These rules can be discovered from data using data mining techniques or domain experts’ knowledge. We demonstrate a system that provides its users the means for creating and validating such rules. The sys-tem is applied on real-life environmental scenarios, where the main source of data comes from sensors. Based on historical data about events of interest, the scope is to formulate rules that could have caused these events. Using a scalable infrastructure the rules can be tested on massive amount of data in order to ob-serve how past events would fit to these rules. In addition, we create semantic annotations of the dataset and use them in the system outputs in order to support interoperability with other systems.

Highlights

As part of activities in the FP7 CREW project the Department of Communication Systems at JSI installed two VESNA SNE-ESTHER devices in London. SNE-ESHTER is a radio receiver for the UHF band designed at JSI based on the VESNA sensor platform. Installed devices will be used for advanced spectrum sensing, contributing to the large scale Ofcom TV White Spaces pilot. One device was installed on the roof of a building in the King's College London Strand campus and the other on the roof of Queen Mary University London. Long term measurements will be used to support the experimentation with advanced, so called cognitive radio devices, as secondary users in currently unused parts of the spectrum.

Marko Pesko, Miha Smolnikar, Matevz Vucnik, Tomaz Javornik, Milica Pejanovic-Djurisic and Mihael Mohorcic published a paper titled "Smartphone with augmented gateway functionality as opportunistic WSN gateway device" in Wireless Personal Communications journal. They described how a Samsung phone connected via Bluetooth to a VESNA sensor node can act as a gateway to a wireless sensor network.

Chapter "Low-cost testbed development and its applications in cognitive radio prototyping" written by our colleagues Tomaž Šolc, Carolina Fortuna and Mihael Mohorcic has been published by Springer in the book  "Cognitive Radio and Networking for Heterogeneous Wireless Networks" from the Recent Advances and Visions for the Future series.

Jernej and Klemen talked with Nickola Naous about our new VESNA sensor node design. Read about The engineers behind the WSN Vesna on the IoTMonkey blog.

The CREW project entered a continuous open access phase. You can test your cognitive radio networking solution on 5 differrent testbed islands and advanced radio components, including our LOG-a-TEC testbed and the VESNA sensor network platform.

In cooperation with Adria Mobil we are developing a motorhome for the future. Adria Moving Lab is equipped with intelligent sensors that allow the vehicle to adapt to its user. This way we can optimize the use of consumables like fuel and water and exploit renewable sources of energy like solar power. The prototype has been unveiled at the Institute Jožef Stefan open days in April 2014.

Our paper "Trends in the development of communication networks: Cognitive networks" is the 10th among the 25th most cited articles published since 2009, extracted from Scopus, see all on the Elsevier web site.

Check the "Cognitive radio experimentation with VESNA platform" presentation by Miha Smolnikar at the School on Applications of Open Spectrum and White Spaces Technologies.

We are looking for a C programmers that would join the team developing the VESNA platform. Candidates that have previous experience with electronic circuit design, operating systems or open source projects will have priority.

 

We are constantly open for talented, open minded and hard working undergraduate students, interns and MSc/PhD candidates. Read more.
