    34 The above figures show 300 seconds of data from the experiment. In the first figure, the black line shows the total sum throughput that was sustained in the network. The ~12.5Mbps that was achieved is just slightly below the [wiki:802.11/Benchmarks/Throughput#Throughputvs.PayloadLength theoretical max] throughput that can be achieved at the 18 Mbps PHY rate. The slight reduction is due to the overhead of the DCF along with unavoidable collisions among the 6 traffic flows.

    3636The IBSS project is very useful in research applications in that there is no topological requirement for flow connectivity. Any device can establish a wireless link to any other device on the same IBSS. All source code used to generate the data and figures in this application note is available below.
