Launching an experiment with OpenWSN

After you have a running VM as indicated in Installing a VM with all software and tools, you can start the OpenWSN experiments

  1. [Once] Before running the experiment for the first time, you need to automatically get and compile necessary packages and code from repositories. In directory exp-iotlab use:
make openwsn-exp-deps USE_DEMO_REPO=yes

The option USE_DEMO_REPO will use in some case(s), fork(s) of repositories with minor modifications, instead of main repositories.

  1. [Optional] Reserve some nodes independenly.

There are three ways to select nodes for an experiments:

  • either make a reservation through https://www.iot-lab.info/ and then you can select experiment duration, site, and nodes

  • use web-view, select some nodes and grab them:

    cd tools
./expctl web-view

    and click on [web-view]; in the new window, select the nodes, and click on [grab]

  • or through command line arguments of the script ExpOpenWSN.py

Actually, ExpOpenWSN.py first tries to find an active node reservation at the IoT-LAB server; and if it does not find one, it would use command line arguments (with default values), to make itself a reservation.

  1. If you have not reserved nodes (step 2):
cd tools
python ExpOpenWSN.py --site grenoble --nb-nodes 5 --duration 20

otherwise you can run simply:

cd tools
python ExpOpenWSN.py
  1. Tunnel the port of the sink (and actually all OpenWSN nodes) through ssh to IoT-LAB experiment server:
./expctl ssh-forward
  1. Redirect the port of the sink through socat in /tmp/tty
./expctl pseudo-tty
  1. Run the web interface (in directory exp-iotlab/)
cd .. && make run-openwsn-web

and open the OpenVisualizer web interface in another window:

xdg-open http://localhost:8080/
  1. "Select mote..." choose one of them, and then you have the OpenWSN interface for the Sink.
