Running tests

A sample test

To see an example of how to run a test, please take a look at this page. The page will explain how to setup 10 nodes in the testbed (using the custom compiled madwifi driver), where one of the nodes will run hostapd with WPA-PSK. The rest of the nodes will be configured to connect to the access point.




Scripts

There has been written a few scripts to be able to configure the testbed (or a number of nodes in the testbed) for your convenience when running tests. The scripts and their function can be found on this page.




Configuration

NDlab IP address setting

We keep the IP address assigments in NDlab here. If you are associated to Networks and Distributed Systems Group and require an IP address to work inside the lab, kindly send your request via email to naeemk [at] ifi [dot] uio [dot] no.

Hardware

The 802.11 test-bed is consisting of:


  1. 10 Dell OptiPlex GX620 PCs each equipped with a D-Link AirPlus DWL-G520 Wireless PCI Adapter(rev.B) with Atheors AR5001X+ chipset and madwifi-0.9.4 as defualt driver module. Some of these PCs are equipped with 802.11n NICs as well. [pc01-pc10]
  2. 5 Dell OptiPlex GX620 PCs each equipped with a Compex WLM54AG 802.11a/b/g Adapter with Atheros AR5413 chipset and madwifi-0.9.4 as default driver module. [pc11-pc15]
  3. 4 Dell OptiPlex GX620 PCs each equipped with a AirForce One 54g Adapter with Broadcom BCM4318 chipset and b43 as default driver module. [pc101-pc104]
  4. 1 file server (host server called ashoka) maintaining projects/experiments files on a shared folder. [ashoka]
