WiMAX Tutorial at GEC14
Wednesday, July 11
8:30 am - 10:30 am
Active participants: max 8x3 = 24
Auditors: Anyone is welcome to attend, even if you haven't registered!

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.
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:
- Wireless Sensor Networks
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!
Participants in this tutorial will benefit from some familiarity with OMF. Attendees with no previous OMF experience should consider attending the OMF tutorial on Monday.
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 link.
Active participants will need a laptop equipped with an SSH client (such as Putty for Windows) and a web browser.
1. Introduction to GENI WiMAX
Aim: Motivation for GENI WiMAX, and brief overview.
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.
2. Arrangements for this tutorial
Aim: Divide participants into groups for the rest of the tutorial and login to testbeds using assigned credentials.
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.
3. Designing an experiment for GENI WiMAX
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.
The three tracks are:
- HetNets? Track: Design an experiment to evaluate a protocol for cooperative recovery over WiFi? and WiMAX networks (WINLAB sb4) slides
- 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 slides
- 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) slides
Each group will cover the following lessons in the context of their given track:
- Choosing a connectivity option for testbed nodes (local network, public Internet, GENI backbone) that makes sense for the given experiment
- Choosing resources (sb4, wireless sensor network, etc.)
- Selecting OML-ized applications (iperf, HTTP server/client, sensor app, social app, BitTorrent?) to use for the experiment
Setting up a WiMAX testbed in preparation for an experiment
- Load baseline disk image
- Restart base station to default settings
- Assign WiMAX clients to the selected VLAN
Use basic WiMAX functionality in OMF
- Connect to the WiMAX network
- Assign an IP address to a WiMAX client
- Configure a WiMAX base station
- Use an OML-instrumented application from OMF
Conducting ongoing experiments
- Saving a disk image for later use
- Extending and revising an OMF script
- Retrieving experimental results from OML and post-processing
Aim: Solidify lessons learned and communicate results between groups.
One or more representatives from each group will briefly describe the experiment design process and demonstrate the experiment.
