static TypeId GetTypeId (void)
 This method returns the TypeId associated to ns3::LogDistancePropagationLossModel.

Detailed Description

a log distance propagation model.

This model calculates the reception power with a so-called log-distance propagation model: $ L = L_0 + 10 n log_{10}(\frac{d}{d_0})$

where:

  • $ n $ : the path loss distance exponent
  • $ d_0 $ : reference distance (m)
  • $ L_0 $ : path loss at reference distance (dB)
  • $ d $ : distance (m)
  • $ L $ : path loss (dB)

When the path loss is requested at a distance smaller than the reference distance, the tx power is returned.
