| | 25 | == Abstract == |
| | 26 | |
| | 27 | The purpose of this tutorial is to provide hands-on experience with step-by-step guidance in designing and conducting a GENI WiMAX experiment. Participants will learn how to reserve WiMAX resources, configure a GENI WiMAX base station, and develop and execute an OMF experiment using WiMAX-equipped clients. |
| | 28 | |
| | 29 | |
| | 30 | Active participants will be divided into three groups. Each group will work closely with an instructor to develop a non-trivial experiment in one of these three areas: |
| | 31 | * HetNets |
| | 32 | * Wireless Sensor Networks |
| | 33 | * Education |
| | 34 | |
| | 35 | |
| | 36 | This tutorial is quite different from the WiMAX tutorial at GEC13, so participants in the GEC13 tutorial are welcome to attend this tutorial as well! |
| | 37 | |
| | 38 | == Prerequisites == |
| | 39 | |
| | 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]] |
| | 51 | |
| | 52 | [http://groups.geni.net/geni/attachment/wiki/GEC14Agenda/WiMAXTutorial/WiMAX%20Tutorial%20GEC14.pdf WiMAX overview slides] [[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. |
