Testing our wireless ad hoc network setup under realistic propagation losses
In order to simulate a real-time wireless environment, letâs configure ns-3âs LogDistancePropagation loss model and observe the network performance results using ns-3âs ConstantRate, Arf, and Minstrel rate control algorithms:
./ns3 run scratch/pkt-adhoc -- "ns3::ConstantRateWifiManager" Average throughput at Sink-1: 0.075136 Mbit/s Average throughput at Sink-2: 0 Mbit/s /ns3 run scratch/pkt-adhoc -- "ns3::ArfWifiManager" Average throughput at Sink-1: 0.075136 Mbit/s Average throughput at Sink-2: 0 Mbit/s ./ns3 run scratch/pkt-adhoc -- "ns3::MinstrelWifiManager" Average throughput at Sink-1: 0.075136 Mbit/s Average throughput at Sink-2: 0 Mbit/s
When simulating an ad hoc network using the LogDistancePropagtionLoss model, changing the rate control algorithm alone is not helping. Letâs check whether enabling RTS/CTS helps improve the network performance:
./ns3 run scratch/pkt-adhoc -- "ns3::MinstrelWifiManager" Average throughput at Sink-1: 0.075136 Mbit/s Average throughput at Sink-2: 0 Mbit/s
Oh! There is still no improvement in the throughput at the sinks. Letâs inspect what is happening at Sink-2 using NetAnim.
