VESNA

VESNA is a modular and fully flexible platform for the development of wireless sensor networks developed at the SensorLab @ Jozef Stefan Institute. Based on the high-performance microcontroller with ARM Cortex-M3 core and radio interface spanning over multiple ISM frequency bands it is designed to meet the requirements of diverse applications.

In terms of modularity the platform consists of the VESNA core module and a set of special feature modules (sensor node radio – SNR, sensor node expansion – SNE, sensor node power – SNP) that are used as/if needed. Various peripherals including UART, I2C, SPI, USB, ADC and DAC allow hosting of different sets of sensors and/or actuators including sensors for temperature, humidity, luminance, color, reflectance, pressure, presence, location, sound, acceleration, gasses, motion, range, and actuators such as motor, relay, servo, alarm, … The platform readily supports:

  • communication standards IEEE 802.15.4, IEEE 802.15.1 and IEEE 802.11; 
  • ZigBee, 6LoWPAN, Bluetooth and Wireless M-Bus protocol stacks and technologies; 
  • operating system Contiki; 
  • connection to the Internet via Wi-Fi, Ethernet or GSM/GPRS; 
  • Arduino integrated development environment
  • a variety of energy supply options including battery, solar panel and external power supply. 

 

Depending on the needs of application it can either come in bare metal variant or running a Contiki. Soon it will become Arduino compatible. It can as well be used to implement fixed or mobile gateway solutions based on Ethernet, GSM/GPRS, Wi-Fi, Bluetooth and HSPA communication networks.

Highlights

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.
