Now let us talk about building a mobility model with NS3.

HOW TO BUILD MOBILITY MODEL USING NS3 LTE?

Let us try to understand the building models like BuildingPropagationModel classes and MobilityBuildingInfo in NS3 simulation of LTE (in indoor and building nodes)

• // Header files

#include <ns3/mobility-building-info.h>

#include <ns3/buildings-propagation-loss-model.h>

#include <ns3/building.h>

•  // Selection of Pathloss model

Ptr<LteHelper> lteHelper = CreateObject <LteHelper> ();

lteHelperàSet attribute (“PathlossModel”, StringValue (“ns3 :: BuildingsPropagationLossModel”));

• // Selection of EUTRA Band

Propagation working frequency selection is done using the NS3 attribute system. It happens with the help of UIEarfcn and DIEarfcn parameters. An example is stated below for your reference.

lteHelper ->SetEnbDeviceAttribute (“DlEarfcn”, UintegerValue (200));

lteHelper ->SetEnbDeviceAttribute (“UlEarfcn”, UintegerValue (10000));
