TARWIS Tutorial 5
Experiment Configuration

 

After you have reserved nodes you next need to configure the experiment that will be performed in this reservation. Configuration of an experiment includes the binary code images and configuration commands for the sensor nodes, the number of times that the same experiment should be performed, and additional information such as an experiment description.

  1. By clicking on the Configure Experiment for Reservation button (cf. (H) in Fig. 39) after reservation or via the Experiment Configuration -> My Experiments tab (cf. Fig. 44) the user can configure their experiments using the dialog shown in Fig. 45.

Figure 45: Configuration: image, description, number of runs, automated commands
  1. First, the user can optionally use an "experiment template". This includes the images of the selected nodes, the description, the number of runs and the set of automated commands used for the experiment. Using a template is useful if the user wants to perform a series of similar experiments.
  2. The user can choose their binary code which will be uploaded to the selected sensor nodes. They can choose one image for all nodes or different images for different sensor nodes.
  3. Name and a Description can optionally be entered.
  4. If the user checks the public experiment checkbox, the experiment can be monitored by every TARWIS User and TARWIS Viewer.
  5. If running more than one repeat of the experiment within the reserved time the user can select the number of runs and how often the experiment should be repeated. The time of a run is automatically divided throughout the reserved time. After each run the nodes are reset and the experiment starts again.
  6. To configure the nodes or control the experiment the user may add commands which are transmitted to the sensor nodes at the chosen time. The commands are transmitted to the sensor nodes using the serial interface and have to be interpreted and executed by the user's software on the sensor node. A command can be sent to all or selected sensor nodes.
  7. On the right side, the map with the selected sensor nodes and additional information (such as (ID, type, description, capabilities) is displayed.
  8. Clicking on the Finish button completes the experiment configuration sheet.

Figure 46: Configuration: configured experiment
  1. After finishing, the configuration data of the experiment is depicted (cf. Fig. 46), like experiment ID, name and description of the experiment, start and end time and number of runs, and
  2. The selected sensor nodes with the selected images.
  3. Furthermore, the user can save the current configuration into a template for re-using with further experiments.

By clicking on Experiment Configuration -> My Experiments (cf. Fig. 44) the user can finds its experiments, the unconfigured ones and the configured ones (cf. Fig. 47).

PIC
Figure 47: Configuration: my experiments
  1. The user can find again the configuration data of all its experiments, like experiment ID, name and description of the experiments, and start and end time as well.
  2. To modify the experiment configuration, the user can press the Modify Experiment button.
  3. To delete the experiment configuration, the user can press the Delete Experiment button.
