This page describes how to run experiments in the GENI WiMAX testbeds. The The steps you would like to follow are :

  • Learn more about the GENI WiMAX testbeds
  • Get an account. Currently the WiMAX testbeds use a separate set of accounts other than the GENI credentials.
  • Run an experiment on a WiMAX testbed.

GENI WiMAX

Currently there are two WiMAX testbeds that are open to experimenters :

Resources

A GENI WiMAX testbed includes a number of components :

Login to Flack Video
  • A console that runs a set of services that help you manage and execute your experiment
  • A WiMAX base station
  • A set of nodes, which may include laptop computers, Android phones, or special PCs colloquially referred to as yellow boxes

WiMAX configuration

The WiMAX base stations are designed to "just work" in their default configuration. However, if you would like to change the settings on the base station, you can find the syntax here (refer to the TOC on the right of the page for links to specific settings).

Testbed Reservation

Each site might have one ore more testbeds. As these are wireless testbeds, it is difficult to run multiple experiments without interference. Therefore, we currently only support one experiment at a time on each testbed. Read the section for each individual testbed for instructions on how to reserve it.

Existing testbeds

NYU Poly testbed

The NYU-Poly facility only has a single testbed. When you make a reservation at NYU-Poly, you have reserved the entire testbed, including all nodes and the WiMAX base station. You can read more about the specific resources of the NYU-Poly testbed here.

In order to reserve a testbed you may visit the following links (using the account you have set up on a GENI WiMAX testbed) to reserve WiMAX resources:

The WINLAB testbed

The WINLAB facility includes multiple testbeds. WiMAX nodes are available on the following testbeds:

  • grid (make a reservation for grid and wimax)
  • outdoor (make a reservation for outdoor and wimax)
  • sb6 (make a reservation for sb6 and wimax)
  • sb7 (make a reservation for sb7 and wimax)
  • sb8 (make a reservation for sb8 and wimax)
  • sb4 (make a reservation for sb4 - you do not need to also reserve wimax, because sb4 has its own base station that is reserved automatically).

You can read more about the specific resources of the WINLAB testbed here.

In order to reserve a testbed you may visit the following links (using the account you have set up on a GENI WiMAX testbed) to reserve WiMAX resources:

Tools and Services

OMF

OMF is a platform to support rigorous and repeatable experiments in a wireless environment. It provides an unambiguous way to describe an experiment, thus enabling repeatability.

One OMF experiment can run on any GENI WiMAX testbed with minimal modifications.

You don't have to use OMF to run experiments on a GENI WiMAX testbed - you may also run experiments manually by logging on to each node via SSH and executing commands on the nodes yourself. However, once you have figured out exactly how you want to configure your resources and what commands you want to run on them, OMF makes it much easier to run, refine, and repeat your experiment.

OML

OML is a measurement library and framework that provides a method for instrumenting experiments to stream measurements to a storage server during execution. The measurements are saved in a standard database format, which you can retrieve later for data analysis and visualization.

Supported Applications

A number of commonly used applications and utilities (e.g. iperf, VLC) have been instrumented with OML to enable their use in OMF experiments. More information about these applications is available at:

Get a WiMAX account

Currently the WiMAX testbeds require separate accounts from the GENI accounts. The WiMAX testbeds

if you would like to create an account for your later use, you can register at either of the open-access GENI WIMAX testbeds:

Run a WiMAX experiment

In order to run your first WiMAX experiment you will need to :

  1. [ Get your WiMAX accounts]
  2. [ Reserve

Experiment Deployment and Execution

A set of simple tutorial exercises have been prepared to help familiarize you with the process of running an experiment on a GENI WiMAX testbed.

To run these exercises, use an SSH client (such as Putty for Windows) to log on to your testbed console using the username and password that have been provided for you.

For example, if your username is "tutorial01", your password is "gec15", and your console is "witestlab.poly.edu", then SSH into tutorial01@witestlab.poly.edu and enter gec15 when you are prompted for a password. If you are using the sb4 testbed at WINLAB, your console is sb4.orbit-lab.org.
