| 40 | | Participants in this tutorial will benefit from some familiarity with OMF. Attendees with no previous OMF experience should consider attending the [http://groups.geni.net/geni/wiki/GEC14Agenda/OMFTutorial OMF tutorial] on Monday. |
| 41 | | |
| 42 | | Attendees may benefit from familiarizing themselves with the GENI WiMAX testbeds by making an account at a GENI WiMAX site and running the preliminary experiments [http://witestlab.poly.edu/index.php/tutorial.html link]. |
| 43 | | |
| 44 | | Active participants will need a laptop equipped with an SSH client (such as [http://www.chiark.greenend.org.uk/~sgtatham/putty/ Putty] for Windows) and a web browser. |
| 45 | | |
| 46 | | == 1. Introduction to GENI WiMAX == |
| 47 | | |
| 48 | | '''Aim:''' Motivation for GENI WiMAX, and brief overview. |
| 49 | | |
| 50 | | In this section, we will introduce the motivation for GENI WiMAX sites, and also give a brief overview of the architecture of the WiMAX testbeds. [[br]] |

| 53 | | |
| 54 | | == 2. Arrangements for this tutorial == |
| 55 | | |
| 56 | | '''Aim:''' Divide participants into groups for the rest of the tutorial and login to testbeds using assigned credentials. |
| 57 | | |
| 58 | | Participants will divide into three groups. Each groups will work closely with an instructor to develop an experiment showcasing the use of GENI WiMAX testbeds for wireless research or education. |
| 59 | | |
| 60 | | |
| 61 | | |
| 62 | | == 3. Designing an experiment for GENI WiMAX == |
| 63 | | |
| 64 | | '''Aim:''' Participants will work in groups, guided by an instructor, to develop and execute an experiment to answer a significant research question or serve some educational purpose. |
| 65 | | |
| 66 | | |
| 67 | | The three tracks are: |
| 68 | | |
| 69 | | * HetNets Track: Design an experiment to evaluate a protocol for cooperative recovery over WiFi and WiMAX networks (WINLAB sb4) [http://groups.geni.net/geni/attachment/wiki/GEC14Agenda/WiMAXTutorial/WiMAX%20Tutorial%20GEC14%20-%20HetNet.pdf slides] |
| 70 | | * WSN Track: Design an experiment that sets up a wireless sensor network at one testbed site (NYU-Poly) and transmits sensor measurements over the WiMAX link and the GENI backbone to nodes at another site (BBN) for processing and serving a meaningful display on the public Internet [http://groups.geni.net/geni/attachment/wiki/GEC14Agenda/WiMAXTutorial/WiMAX%20Tutorial%20GEC14%20-%20WSN.pdf slides] |
| 71 | | * Education track: Design an instructional lab experiment that students can run to learn about key properties and capabilities of wireless broadband networks (e.g. modulation and coding, ARQ) [http://groups.geni.net/geni/attachment/wiki/GEC14Agenda/WiMAXTutorial/WiMAX%20Tutorial%20GEC14%20-%20Edu.pdf slides] |
| 72 | | |
| 73 | | Each group will cover the following lessons in the context of their given track: |
| 74 | | |
| 75 | | '''Experiment design''' |
| 76 | | * Choosing a connectivity option for testbed nodes (local network, public Internet, GENI backbone) that makes sense for the given experiment |
| 77 | | * Choosing resources (sb4, wireless sensor network, etc.) |
| 78 | | * Selecting OML-ized applications (iperf, HTTP server/client, sensor app, social app, BitTorrent) to use for the experiment |
| 79 | | |
| 80 | | '''Setting up a WiMAX testbed in preparation for an experiment''' |
| 81 | | * Load baseline disk image |
| 82 | | * Restart base station to default settings |
| 83 | | * Assign WiMAX clients to the selected VLAN |
| 84 | | |
| 85 | | '''Use basic WiMAX functionality in OMF''' |
| 86 | | * Connect to the WiMAX network |
| 87 | | * Assign an IP address to a WiMAX client |
| 88 | | * Configure a WiMAX base station |
| 89 | | * Use an OML-instrumented application from OMF |
| 90 | | |
| 91 | | '''Conducting ongoing experiments''' |
| 92 | | * Saving a disk image for later use |
| 93 | | * Extending and revising an OMF script |
| 94 | | * Retrieving experimental results from OML and post-processing |
| 95 | | |
| 96 | | |
| 97 | | == 4. Review == |
| 98 | | |
| 99 | | '''Aim:''' Solidify lessons learned and communicate results between groups. |
| 100 | | |
| 101 | | One or more representatives from each group will briefly describe the experiment design process and demonstrate the experiment. |
| | 35 | * Attendees may benefit from familiarizing themselves with the GENI WiMAX testbeds by making an account at a GENI WiMAX site and running the preliminary experiments [http://witestlab.poly.edu/index.php/tutorial.html link]. |
| | 36 | * Active participants will need a laptop equipped with an SSH client (such as [http://www.chiark.greenend.org.uk/~sgtatham/putty/ Putty] for Windows) and a web browser. |
