The Idea

Challenge:

In some stadiums, sports fans can view personal video feeds through their mobile devices. However, it is difficult to guarantee the reception reliability of these devices because each user experiences different wireless channel conditions.

Solution:

Take advantage of the multiplicity of radios on modern devices and their physical proximity in a stadium to allow cooperative packet recovery over a secondary network.

  • Wireless devices are connected to the principal network (WiMAX) to receive broadcast data such as live video feeds
  • A wireless device may lose some of the data sent over the principal network
  • Physically co-located wireless devices form an assistant network over WiFi to recover the lost data cooperatively from their peers

We have implemented this technique in an application called 'coopshim'

The Scenario

In this experiment, we're going to evaluate the performance of 'coopshim'

We'll follow the process of preparing this experiment to run with OMF+OML, set up the experiment, run the experiment with different settings, and do some basic analysis and visualization on the results.
