II. Description of work performed during last quarter

In the 1st quarter of 2012, the installation and configuration of the experimentation server software is completed. The software consists of a central XMPP server that exchanges messages with the remote nodes to determine if they are alive and with the OMF server that reads the nodes’ status. In order to gather results during an experiment, an OML (Orbit Measurement Library) server is installed that outputs the results in a SQLite file. The services that are enabled on the OMF server are the Frisbee, inventory, PXE, result, and save image services. This enables us to restart, PXE boot, and save/load a disk image of/on the node. Utilizing the result service, we are also able to see live results while an experiment is being conducted.

We have also setup stationary nodes for WiMAX experimentation. Currently, the NEC base station on the Waisman Center has two nodes in surrounding buildings. One is located within the Waisman Center and another is stationed in the Wisconsin Institutes of Medical Research building nearby. Due to the bottleneck of the WiMAX uplink, a third virtual machine is installed in a computer at the Computer Science building that has access to the WiMAX network for testing the downlink using a wired interface.

We created a website frontend for conducting pre-configured experiment description files. The system works by selecting the type of test (iperf/ping/etc.) and which nodes the test will control. The nodes are selected by checkboxes for senders and then by selecting receivers. Once the test is underway, live results (throughput/RTT, RSSI,CINR,etc.) can be seen through an auto-updating graph. Once the experiment is completed, a post processing results page is updated with zoom-able graphs of the result and download options in either sq3 or csv files.

Working with Madison Metro Transit, the WiRover system has been updated to include WiMAX. Currently only one bus is outfitted with WiMAX to discover and remove any issues that may appear.

The preparations for the installation of the Airspan base station is underway. We have received our experimental FCC license under the callsign WF2XXF and permission has been granted to install the base station on the City-County building in downtown Madison. The data will be backhauled through the Madison Unified Fiber Network (MUFN project) to the Computer Sciences building.

A. Activities and findings

B. Project participants

In UW-Madison --- Joshua Hare, Lance Hartung, Wes Miller, and Derek Meyer

C. Publications (individual and organizational)

D. Outreach activities

E. Collaborations

  • Collaborations are ongoing with two local bus operators:
    1. Madison Metro Transit --- which operates city transit services in and around Madison, WI; and,
    2. Van Galder Bus --- which operates buses on various long distance routes between Madison, Milwaukee, Chicago, and Minneapolis.

Both these partners are using our WiMAX and in-vehicle node deployment to provide Internet services to their vehicles and passengers with great success and evaluating them for larger scale deployments.

F. Other Contributions

We are also collecting a large volume of user performance data on Internet access services from moving vehicles. This performance data will be published soon.
