| 18 | == Experiment Procedure == |
| 19 | |
| 20 | The experiment procedure is as follows: |
| 21 | |
| 22 | * The first peer visits the [http://witestlab.poly.edu/~ffund/webrtc/webrtc-read-only/samples/js/demos/html/webrtc-oml.html URL] for the WebRTC app in Google Chrome. A bar at the top of the screen will ask if you are willing to let the browser access your camera; don't click allow until the second peer has joined the chat! |
| 23 | * The second peer visits the same [http://witestlab.poly.edu/~ffund/webrtc/webrtc-read-only/samples/js/demos/html/webrtc-oml.html URL] |
| 24 | * Both peers click "Allow" and should now see video streams from each other's webcams |
| 25 | |
| 26 | == Post-Experiment == |
| 27 | |
| 28 | After the experiment, the OML-instrumented peer will send the measurement results to iRODS using the {{{iput}}} command. |
| 29 | |
| 30 | |
| 31 | Inside iRODS, we'll use the iRODS web browser to visualize the results of our experiment. |
| 32 | |
| 33 | == Reconfiguring the WiMAX BS == |
| 34 | |
| 35 | A major advantage of on-campus WiMAX (over using a regular cellular carrier) for experimentation, is that you can reconfigure the WiMAX BS. In this experiment, we'll try using WebRTC with and without link-layer retransmission (ARQ) and observe the effect of ARQ on latency, packet loss, and video rate. |
