Testing our wireless ad hoc network setup under realistic propagation losses

In order to simulate a real-time wireless environment, let’s configure ns-3’s LogDistancePropagation loss model and observe the network performance results using ns-3’s 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. Let’s 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. Let’s inspect what is happening at Sink-2 using NetAnim.
