WiFi Virtual Laboratory Primer
Go to http://wifi.cs.st-andrews.ac.uk/
and enter the virtual laboratory section.
- Try loading and running some of the pre-defined scenarios.
- Try creating a simple two node scenario:
- create two nodes, with co-ordinates e.g. 60,60 (node 0) and 100, 60 (node 1)
- create some traffic between the nodes. Go to the "Add A Traffic Link" section and create a link between Node 0 and Node 1
- use TCP and FTP for the application and transport (defaults)
- pick a start time e.g. 0 and an end time e.g. 1
- click on "Add Traffic Link" button
- set sensing range - this should be larger than the distance between the node co-ordinates to ensure that nodes can reach each other
- generate the simulation - click on "Generate" button
- optionally, before submitting, save the simulation configuration by copying the URL string into a document
- when ready, click on "Submit Data To Server"
- the simulation should start automatically. Watch the visualisation.
- try adjusting the speed
- try using the pause and start buttons, and the time bar
- study the event history
- Create a scenario with four or more nodes. Again, this can be
saved by copying and pasting into a text document. Pay particular
attention to the use of RTS/CTS exchanges when the simulations are
running. Use the speed control and pause button if necessary.
