Measuring throughput in wireless networks: iperf vs nuttcp

As part of my PhD thesis, I investigate the impact of interference on the network performance in large-scale multi-hop wireless mesh networks. Most experiments are based on throughput measurements to determine the maximum capacity of a link in interference-prone scenarios. iperf has almost become the standard traffic generator for this task in wire line and wireless networks alike. However, control packets to signal the start and end of a traffic flow are exchanged between the two endpoints of the measurements on the same channel that is subject to the measurement. In wireless networks with possible high levels of interference, these
