-  - Run the command “emuRun experiment.xml” . This will emulate the experiment and write out results into files in the same directory. The output files all have names starting with exp01. Most of the stderr files created will usually be empty and you can delete such empty file using the command “ file -size 0 -delete” so that you can concentrate on the rest of the non-empty files that have the iperf command output with data transfer rates. Take a look at the result files.+  - Run the command “emuRun experiment.xml” . This will emulate the experiment and write out results into files in the same directory.

   - Now change the experiment.java file so that you can gather enough data to present on how distance of separation between wireless nodes affect the data transfer rates.   - Now change the experiment.java file so that you can gather enough data to present on how distance of separation between wireless nodes affect the data transfer rates.
   - Once you have completed executing the experiment, we will have to swap out the experiment so that the physical resources held by this experiment are released for use by others. For this, go to the https://​boss.cmcl.cs.cmu.edu/​ and click on "My Emulab"​ link under "​Experimentation tab". On the page that shows up, click on the EID link and you will be taken to the experiment page. Click on Swap "​Experiment Out" link on the left menu. Once the swap out completes, login to emucontrol-1.ece.cmu.edu and type the command "​emulatorDaemon <​username>​ emulator <​experimentname>"​. This command will complete the swap in process. This step is very important.   - Once you have completed executing the experiment, we will have to swap out the experiment so that the physical resources held by this experiment are released for use by others.
