Not getting remaining energy of ALL nodes at time T with Basic Source Helper

[Francisco Eduardo Balart Sanchez]

Good day:

In the beginning i had my energy model setup as shown below

  for (uint32_t i = 0; i < numOfNodes; ++i)

  {

    Ptr<BasicEnergySource> energySource = CreateObject<BasicEnergySource>();

    Ptr<WifiRadioEnergyModel> radioenergyModel = CreateObject<WifiRadioEnergyModel>();

    energySource->SetInitialEnergy (double (100));

    energySource->SetEnergyUpdateInterval (t1);

    radioenergyModel->SetEnergySource (energySource);

    energySource->AppendDeviceEnergyModel (radioenergyModel);

    radioenergyModel->SetTxCurrentA (double (0.0174));

    radioenergyModel->SetRxCurrentA (double (0.0174));

    nodes.Get (nodeIndexxx)->AggregateObject (energySource);

    nodeIndexxx++;
}

But later i switched to use the helper as the example and as per recomendation, now my setup is the following

  BasicEnergySourceHelper basicSourceHelper;

  basicSourceHelper.Set ("BasicEnergySourceInitialEnergyJ", DoubleValue (100));

  basicSourceHelper.Set ("PeriodicEnergyUpdateInterval", t1);

  EnergySourceContainer sources = basicSourceHelper.Install (nodes);

  WifiRadioEnergyModelHelper wifiRadioEnergyModelHelper;

  wifiRadioEnergyModelHelper.Set ("TxCurrentA", DoubleValue (0.0174));

  wifiRadioEnergyModelHelper.Set ("RxCurrentA", DoubleValue (0.0174));

  DeviceEnergyModelContainer deviceModels = wifiRadioEnergyModelHelper.Install (devices, sources);

And the trace connection is performed (can be done in several ways these is mine)

  int iii = 0;

  uint32_t nDevices = devices.GetN ();

  for (uint32_t i = 0;i < nDevices; ++i)

  {

    Ptr<WifiNetDevice> p = DynamicCast<WifiNetDevice> (devices.Get (i)); 

    p->SetAddress(Mac48Address::Allocate ());  

    Ptr<EESOA> macN = DynamicCast<EESOA> (p->GetMac());

    macN->SetNodeId(p->GetNode ()->GetId ());

    prev_role[i]= 100; //this role does not exists.

    prev_nNodes[i]= 0;

    Simulator::ScheduleWithContext (p->GetNode ()->GetId (), MilliSeconds(90), &modify, p, &anim);

    Simulator::ScheduleWithContext (p->GetNode ()->GetId (), Seconds(1), &printNonEESOAtx, p);

    p->GetPhy()->TraceConnect ("PhyTxBegin",PrintID(p->GetNode ()), MakeCallback (&PhyTxBegin));

         Ptr<BasicEnergySource>  basicSourcePtr  =  DynamicCast<BasicEnergySource>(p->GetNode ()->GetObject<EnergySourceContainer>()->Get(0));

    NS_ASSERT (basicSourcePtr != NULL);

    basicSourcePtr->TraceConnect ("RemainingEnergy",PrintID(p->GetNode ()), MakeCallback (&RemainingEnergyTrace)); 

    Ptr<DeviceEnergyModel> basicRadioModelPtr = basicSourcePtr->FindDeviceEnergyModels ("ns3::WifiRadioEnergyModel").Get(0);

    NS_ASSERT (basicRadioModelPtr != NULL);

      iii++;

  }

The remaining energy function

void RemainingEnergyTrace (std::string context, double oldValue, double remainingEnergy)

{

  NS_LOG_UNCOND ("%INFO: TimeStamp: "<<Simulator::Now ().GetSeconds ()<<" segs Node: "<<context<<" Current Remaining energy = "<<remainingEnergy<< " Joules");        

}

That combined with the changes to the animation interface mentioned by John Abraham at:

• https://groups.google.com/d/topic/ns-3-users/YrNgQeO7hBw/discussion
  

Provide remaining energy of the nodes.

Problem

It only shows the remaining energy of the Nodes at such time T  which are active at that exact moment 

It does not show remaining energy of ALL nodes, i require to get it so i can make comparisons see below

50: Node ID: 30  Start sending packet

%INFO: TimeStamp: 50 segs Node: ID: 30   Current Remaining energy = 59.6457 Joules

%INFO: TimeStamp: 50 segs Node: ID: 55   Current Remaining energy = 59.7018 Joules

%INFO: TimeStamp: 50 segs Node: ID: 61   Current Remaining energy = 59.7564 Joules

%INFO: TimeStamp: 50 segs Node: ID: 13   Current Remaining energy = 59.9294 Joules

%INFO: TimeStamp: 50 segs Node: ID: 23   Current Remaining energy = 59.7571 Joules

%INFO: TimeStamp: 50 segs Node: ID: 77   Current Remaining energy = 61.5995 Joules

%INFO: TimeStamp: 50 segs Node: ID: 24   Current Remaining energy = 61.7428 Joules

%INFO: TimeStamp: 50 segs Node: ID: 64   Current Remaining energy = 61.3666 Joules

%INFO: TimeStamp: 50 segs Node: ID: 92   Current Remaining energy = 61.3275 Joules

%INFO: TimeStamp: 50 segs Node: ID: 28   Current Remaining energy = 61.433 Joules

How can i obtain the energy of ALL nodes at such time using the helper

Im using ns3.25

Thanks in advance and best regards

In RemainingEnergyTrace you could cache the last energy report from each node, then log the entire cache.
