  1. Four grid nodes with USRP N210s.
  2. ''dsc-bot.ndz'': disk image loaded onto one pair of nodes. This image has all the prerequisite software to configure the USRPs and execute a house radio bot.

+ 3. ''team-image.ndz'': disk image that contains the team's radio. In the explanation that follows, we use the house bot as the team's radio, effectively placing house bot against house bot.
  4. Scoring packet server: This is server that resides on the grid console (for the practice) and is used by a transmitting nodes to send data packets over the air via USRP as well as by the receiving nodes to submit received packets for scoring.
  5. [attachment:dsc-wildcard.rb]: this is the OEDL experiment script to execute the game.

+ * Image the two nodes to be used for the first team's radios. The example dsc-bot.ndz image contains four different topology configurations, dsc-teamA.rb, dsc-teamB.rb, dsc-teamC.rb, and dsc-teamD.rb. The configurations should be considered to be fixed for purpose of the games, and teams simply choose which topology slot (A, B, C, or D) to place their image. In the case described in this example, the first team is being placed in the team A topology slot. Also, in the example described, we are using a house bot for the participant team so that the example can be tested as-is. Teams should note that they should replace dsc-bot.ndz with their respective team-image.ndz filename:

-By default, the experiment script will execute '''/root/gnuradio/gr-digital/examples/narrowband/bot1_tx.py''' and '''/root/gnuradio/gr-digital/examples/narrowband/bot1_rx.py''' on the transmitter and receiver respectively. Each team will use a separate set of parameters for a very simple bot: a brute-force radio that sends a random number of packets at random intervals. The sender module draws packets from a packet server, while the receiver module delivers packets to the same packet server.  The code is based on the same benchmark radio that was used for Hurdle 3.
